🔧 Component Overview

The DJI Agras T100 OEM Sliding Bearing is the OEM sliding bearing in the spreading auger and boom assembly of the DJI Agras T100, part of the structure feeding granular material from the spread tank to the spinner at a controlled rate.

Feeding granular material from the spread tank to the spinner at a controlled rate is the job description for the spreading auger and boom assembly, and this component is part of how it gets done. The T100 is a working machine — it earns its keep in fill-and-fly cycles, not hangar hours — and every component in the spreading auger and boom assembly is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Auger Motor Cover, Auger Motor, Screw (M40-HC01200120-072040-5103-Y).

Ignore a failing sliding bearing and the bill compounds: downtime in the middle of an application window, collateral wear on the parts around it, and jobs that slip to a competitor while the aircraft sits. Replacing it costs a part; not replacing it costs acres. That trade only runs one direction.

For professional farmers, aerial applicators, and commercial drone operators, this component is how the spreading auger and boom assembly stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The T100 works brutally hard for its living, including:

• Feeding granular material from the spread tank to the spinner at a controlled rate
• Dawn-to-dusk spray campaigns during narrow application windows
• Repeated fill-fly-return cycles with minutes on the ground between loads
• Full-payload takeoffs from field edges, dozens of times per day
• Chemical exposure from fungicides, herbicides, insecticides, and foliar fertilizers
• Pressure-washer rinse-downs at the end of every spray day
• Vibration from eight propulsion motors running at working power
• Transport bouncing on trailers and truck beds between fields
• Temperature swings from cold morning starts to full-sun afternoons

What attacks this component in the field:

• Vibration from the propulsion system every flight hour
• Chemical exposure from spray drift and washdown
• UV degradation across a season outdoors
• Shock loads from field-edge landings
• Grit and dust working into interfaces
• Thermal cycling from dawn starts to afternoon heat
• Stress concentration at mounting points
• Wear from repeated maintenance access

That duty cycle is exactly what retires this component. None of these stresses is dramatic on its own — the accumulation is what does it. This is why structural and mounting parts are inspection items every time the spreading auger and boom assembly is opened up, and why operators who run hard keep spares on the shelf.

A healthy sliding bearing delivers:

• Factory-correct fit in the spreading auger and boom assembly — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Stock the sliding bearing before the season does its work, and the spreading auger and boom assembly never becomes the reason the aircraft sits.

Confirm the bearing is worn before you order one. With the hopper empty and the aircraft powered down, take hold of the auger shaft close to the bearing and try to lift it and rock it sideways. A plain sliding bearing that is still in tolerance gives you almost nothing to feel. One that is worn lets the shaft move visibly in the housing, and you will usually see the shaft rise and drop as you rotate it by hand. Do that check at both ends of the auger, because a bearing at one end can be finished while the other is barely marked.

Separate a worn bearing from a worn shaft before you spend money. Pull the auger and look at the journal, the polished band where the bearing rides. A shaft that is still good is smooth and uniform all the way around. A shaft that has been running in a failed bearing carries a ridge, a groove, or a dull scored band, and it will chew through a new bearing in a fraction of its normal life. If you find scoring, the bearing is a symptom, not the whole repair.

Tell the bearing apart from the auger motor by uncoupling them. Run the motor on its own with the auger disconnected, listen, and watch the current the spreader reports. If the noise and the load are still there with nothing but the motor turning, the fault is inside the motor and a new bearing changes nothing. If the motor runs clean alone and gets rough, noisy, or hot the moment the auger is coupled back up, the drag is downstream and the bearings carrying that shaft are the first place to look.

Look at what the bearing has been shedding. Wipe the housing and the area under it clean, run the spreader empty for a minute, then look again. A fine gray or dark powder collecting around the bearing, or a smear on the shaft that keeps coming back after you wipe it, is bearing material coming out. That is a part in its last stage of life, and it is worth catching there rather than after the shaft has started running metal on metal in the housing.

⚙️ Functional Purpose

The sliding bearing is designed to do one job in the spreading auger and boom assembly and do it to specification: feeding granular material from the spread tank to the spinner at a controlled rate.

The component:

• Serves the spreading auger and boom assembly of the DJI Agras T100 exactly as the factory intends
• Supports feeding granular material from the spread tank to the spinner at a controlled rate
• Maintains the tolerances and interfaces the surrounding parts depend on
• Withstands the chemical, vibration, and washdown environment of agricultural work
• Preserves the sealing and protection strategy of the platform
• Keeps failure modes visible and diagnosable instead of mysterious
• Restores factory behavior immediately upon correct installation
• Protects the more expensive components it works alongside
• Carries the exact DJI specification for its position
• Supports safe, predictable operation under full payload
• Eliminates the guesswork of near-fit substitutes
• Keeps the aircraft inside its designed maintenance program
• Holds up across a full season of professional duty

Function on the T100 is a chain: spreading system performance depends on the spreading auger and boom assembly, and the spreading auger and boom assembly depends on every part in it holding specification. This component is one link in that chain — and chains fail at the worn link, not the average one.

That is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure. The operators with the best uptime records are not the ones with the newest aircraft — they are the ones who replace parts like this when inspection says so, on their own schedule instead of the failure's.

A failing sliding bearing costs you:

• Downtime in the middle of an application window — the most expensive hours in agriculture
• Acres not covered while the aircraft waits on a part
• Collateral wear on the components around the failing one
• Diagnostic hours chasing symptoms instead of causes
• Rework when a temporary fix lets go mid-job
• Customer trust when scheduled work slips
• Higher repair bills the longer the fault runs
• Risk exposure every flight the fault remains aboard
• Resale value on an airframe with deferred maintenance

Fix it on your schedule, not the failure's.

Empty and clean before anything comes apart. Run the hopper out, then vacuum or blow the remaining granular material from the tank, the auger tube, and the outlet. Dry fertilizer is corrosive to hardware and it will pour out of the tube the moment you break the joint, straight into whatever is underneath. Working in a clean tube also means you can actually see the wear you are trying to assess instead of digging it out later.

Support the boom and take the load off the auger before you unbolt anything. Block or hold the boom assembly close to the joint you are opening, and do not lever against the auger tube, the spinner housing, or the motor cover to break a stuck part free. Those are all thin sections carrying the tube, not jacking points, and bending one turns a bearing job into a much larger order. Note the orientation of the auger and the motor coupling before you separate them.

Drive a plain bearing out and in squarely, bearing on its full face. Use a drift or a socket that contacts the whole end of the bearing rather than one edge, and never hammer on the bore or drive the bearing in by striking a shaft passed through it. A plain bearing distorts easily, and a bearing that has been pushed in crooked or belled at one end runs tight on one side, wears oval within hours, and takes the shaft with it. Clean the housing bore and check it is round before the new part goes near it.

Do not open up the bore of the replacement. If the new bearing feels tight on the shaft after it is pressed home, that is not automatically a fault, and reaching for a reamer, a file, or emery cloth is the fastest way to ruin a part that was correct. Fit it, turn the auger by hand through several full revolutions, and feel for a tight spot rather than uniform snugness. If it binds in one position only, the housing or the shaft is out of true. If it is uniformly stiff and frees off as you turn it, let it settle before you condemn it.

⚠️ Common Replacement Indicators

• Visible cracking, deformation, or impact damage
• Stress-whitening at load points
• Loose fit where the part should seat firmly
• Movement or rattle the design does not allow
• Wear marks from parts contacting where they should not
• Fastener holes elongated or damaged
• Chemical or UV degradation of the material
• Damage found during teardown of the assembly
• Misalignment of the components this part positions
• Noise or vibration traced to this position
• Damage after a hard landing or transport strike
• Previous field repair with tape, glue, or improvisation

What kills structural and mounting parts: the compounding of ordinary duty. Chemical exposure attacks materials, vibration works at every interface, UV ages every exposed surface, and washdowns drive water at every seam — repeated across hundreds of cycles per season. Add the occasional hard landing or transport knock and the result is predictable: the part that was fine in spring is the failure point by late season.

Replacement and verification: Replacement is a standard shop task on the T100: open access to the spreading auger and boom assembly, document connections and hardware positions, swap the sliding bearing for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.

Confirm before you order: this is DJI part YC.ST.CG000018. Check the label on your old sliding bearing or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.

A spread rate that wanders on a setting you have already calibrated usually means the auger is not turning at a steady rate, and a dragging bearing is one of the few things that varies with load and temperature the way that symptom does. It typically shows worst on the heaviest, densest product and best on light material, because the extra torque needed to overcome bearing drag is a larger share of the total when the auger is already loaded.

A squeal, chirp, or rhythmic scrape that appears when the spreader starts and changes pitch with auger speed is a dry or worn bearing surface. Run the system with an empty hopper and listen with the airframe still. A noise that tracks auger speed points at the bearings and the shaft. A noise that stays the same regardless of what the auger is doing is coming from the motor or the drive, not from here.

Auger motor over-temperature or over-current warnings during spreading, on a machine that used to run the same product without complaint, mean something is adding drag to the shaft. Before blaming the motor, check for material packed around the bearing and for shaft play. A motor working against a bearing that has gone tight or oval runs hot and pulls current all day, and it will eventually fail from that duty even though the bearing was the actual fault.

A bright polished band on the inside of the auger tube, or witness marks on the flighting edges, says the auger has been running off center and touching the tube. That happens when a bearing has worn enough to let the shaft drop. Finding those marks means you are already past the point where a bearing swap alone restores the assembly, and the tube, the flighting, and the shaft all need looking at before the aircraft goes back to work.

Granular material packing hard into and around the bearing, especially after spreading urea or another hygroscopic product in humid conditions, is both a symptom and a cause. Caked material acts like a grinding compound at the shaft, and it also holds moisture against the bearing between jobs. If you are finding a hard crust there every time you open the assembly, the flush-and-dry routine at the end of a spreading day is where the fix starts, not at the parts counter.

• Pre-contract equipment checks before custom application work
• Mid-season turnarounds where the machine has to fly tomorrow

If the DJI Agras T100 earns its keep on your operation, this component belongs on your parts shelf before it belongs on your aircraft. The time to buy it is before the season, not during the failure.

The part most often confused with this one is a rolling-element ball bearing from elsewhere on the aircraft. Tell them apart in your hand: a sliding bearing is a plain sleeve or flanged sleeve with one continuous bore, no rolling elements, and no separate inner and outer ring. A ball bearing has two rings that move against each other, and if you spin the outer ring it will coast. If the part you are holding coasts when you spin it, it is not this part.

It is also confused with a plain spacer or collar, which can share almost the same silhouette. The difference is duty rather than shape. A spacer sets a distance and carries no rotating surface, so it is usually a firm fit on the shaft and shows no polished wear track. A sliding bearing has a running surface, so the bore carries an even burnished band and the shaft turns inside it. If the part you removed had no wear pattern in the bore at all, check the diagram before you order.

Sliding bearings appear at more than one position on the aircraft, and they are not interchangeable just because they look alike. YC.ST.CG000018 is the one listed on the Boom Assembly sheet, alongside the auger motor, the auger motor cover, and the M40 screw for that cover. A bearing of the same outside diameter from a different sheet can have a different bore or a different length and will still press in. Match the diagram position and the material number, not the outline.

💡 Why This Part Matters

Every acre the T100 covers depends on the spreading auger and boom assembly doing its job — and the spreading auger and boom assembly depends on parts exactly like this one.

The economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed sliding bearing is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.

That is the case for OEM and the case for stocking ahead. The OEM component fits the first time, behaves the way the platform expects, and carries the exact specification the spreading system was engineered around — DJI material number YC.ST.CG000018. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the spreading auger and boom assembly — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Running a compromised sliding bearing, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Progressive damage that turns a cheap fix into an expensive one
• Alignment and fit problems spreading to adjacent parts
• Unplanned grounding with the fleet committed to jobs
• Warranty and service complications from improvised fixes
• Higher lifetime cost from deferred maintenance
• An aircraft that cannot be trusted at full payload

Inspect it honestly. Replace it once. Fit it right. Keep it flying.

Ares Acres stocks the sliding bearing in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

While the auger is out, inspect everything that shares its load path. Look at the shaft journal for scoring, the flighting edges for wear and for material picked up from the tube wall, the auger tube bore for a polished band, the motor coupling for slop or a rounded drive feature, and the auger motor cover and its screws for corrosion. A bearing that has worn far enough to be noticeable has been letting the shaft move for a while, and everything downstream of that movement has been taking the difference.

The auger motor is the part that most often fails alongside this bearing, and the order of events matters. A tight or worn bearing loads the motor for every hour it runs, and a motor that has been pulling extra current through a spreading season is on borrowed time even after the bearing is replaced. If you are changing this bearing because the motor was overheating, note the motor's behavior after the repair rather than assuming the problem is closed.

What kills a bearing in this position is abrasive dust combined with moisture, and both are self-inflicted more often than not. Granular fertilizer left in the hopper and the tube overnight draws moisture, cakes, and turns into a grinding paste at the shaft. Washing the assembly out with a pressure washer and then not drying it drives that same slurry into the bearing rather than out of it. Run the hopper empty, flush with low pressure, and let the tube dry before it goes away for the night.

Store and handle the replacement so it is still round when you fit it. Leave it in its bag until the moment it goes in, keep it out of direct sun and away from solvent and fuel on the bench, and never set it down loose in a drawer with metal parts where the bore can pick up a nick or a flat. A plain bearing works because its bore is uniform, and a single dent in that surface becomes the point where the shaft starts to wear it out.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 Sliding Bearing? It is the OEM sliding bearing serving the spreading auger and boom assembly of the DJI Agras T100. It is the genuine DJI Agras component for this position, supplied new.

What is the DJI material number (part number) for the Sliding Bearing? The DJI material number is YC.ST.CG000018, listed on the official DJI Agras T100 parts breakdown. Labels sometimes carry a revision suffix such as .01 or .F — that is the same part; match the base number.

Which DJI Agras models does this component fit? Supplier-listed fitment is DJI Agras T100. Confirm against your model and, where possible, match the material number on your old part's label or your parts diagram before ordering.

How do I know my sliding bearing needs replacing? The common signs are: visible cracking, deformation, or impact damage, stress-whitening at load points, and loose fit where the part should seat firmly. Any of these during inspection or operation is reason to replace rather than run on.

What causes this component to fail? Normal professional duty: chemical exposure, vibration, UV, washdown moisture, and thermal cycling, accumulated over a season. Hard landings and transport knocks accelerate all of it.

How do I confirm the diagnosis before ordering? Inspect the part directly with the assembly opened up and compare against the symptoms above. Match the label on the old part to material number YC.ST.CG000018 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.

What does installation and verification look like? Replacement is a standard shop task on the T100: open access to the spreading auger and boom assembly, document connections and hardware positions, swap the sliding bearing for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.

What other parts should I inspect at the same time? On the official diagram this part sits alongside Auger Motor Cover, Auger Motor, Screw (M40-HC01200120-072040-5103-Y). If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

Where can I buy this part in the USA? Ares Acres is a U.S.-based authorized DJI Agras reseller stocking the Sliding Bearing (YC.ST.CG000018) with free and fast U.S. shipping, plus same-day shipping and tracking on in-stock parts.

Should I grease this bearing?

Not unless DJI specifies a lubricant for this position, and none is published here. In a spreader the surrounding air is full of abrasive dust, and grease on an exposed shaft collects that dust and holds it against the bearing, which turns a lubricant into a grinding compound. A plain bearing that is designed to run dry runs longer dry in this environment than it does packed with grease. Keep it clean instead.

My spread rate drifts but the auger still turns. Is the bearing worth changing?

Check for shaft play first. Lift and rock the shaft next to the bearing with the hopper empty. If there is visible movement, the auger is not holding a steady position and the rate you calibrated is not the rate you are getting, so the bearing is worth doing. If the shaft is tight and the drift persists, look at the motor, the coupling, and material caking in the tube before you spend on a bearing that is not the fault.

The shaft has a groove worn into it. Can I just fit a new bearing?

You can, and it will not last. A new bearing running on a scored journal wears back to where the old one was, usually much faster, because the ridges act like a cutter. Fitting a new bearing on a bad shaft is a way to finish a job today, not a repair. Plan on the shaft as well and treat the bearing swap as temporary until you have it, and check the shaft again at the end of the season.

Do I have to replace both bearings if only one is worn?

Not automatically, but check both and think about the cause. If one end is worn and the other is not, something loaded that end, and the usual suspects are a misaligned coupling, a bent shaft, or material packing on one side only. If both are similarly worn, they have simply done their time and doing both while the assembly is open costs you almost nothing extra in labor, which is the whole expense on this job.
