Technical specification
Supplied brand: Vidishi Auto — not FCS-branded; the original maker is referenced for fitment cross-checks only.
Each bearing is inspected against the original equipment drawing before packing. Tight tolerances keep the unit stable through thermal cycling. The electrical rating is validated across the temperature range. Dimensions are per the OE drawing. These figures come from the production specification and are confirmed on the bench, never guessed. Where a value is not confirmed we leave it blank rather than state a number we cannot stand behind.
The bearing is supplied with the connector and sealing items shown in the gallery, so the installer has everything needed for a clean fit. Torque and clearance follow the original equipment spec.
Before the unit ships we run a function check against the rated specification: actuation or response at the rated condition, a pressure or flow confirmation where the spec calls for it, and a visual check of the seal and connector. The result is either a pass stamped on the carton or the unit is pulled. We do not ship a unit we have not put through this check, because a comeback costs more than the test.

Fitment
Fitment verification
Confirm the engine code plate and the part number H337844 / H337816XD before purchase. This bearing fits the applications in our fitment list. Reference model: H337844 / H337816XD. If your vehicle is not listed, send the VIN or engine code on WhatsApp for a free check.
Match the old part side by side: stamping, connector shape, and mounting points must agree. A wrong revision will not seat and may damage the surrounding circuit.
| Part number | H337844 / H337816XD |
|---|---|
| Reference model | H337844 / H337816XD |
| Verification channel | Send the VIN or a photo of the old part on WhatsApp — written confirmation before you pay. |
Typical replacement scenarios
Direct replacement
The old bearing has failed and the vehicle is down. Match H337844 / H337816XD to the old stamping and fit the same reference — the fastest path back to service.
Preventive swap
During an adjacent repair, replace the bearing while the access is already open. Cheaper than a second teardown later.
Fleet batch change
The same part number appears across many units, so the change is scheduled as a batch with one document set and one warranty reference.
In every scenario the first step is identical — confirm H337844 / H337816XD against the old stamping before the wrench moves.
If the application is not printed on our page, it means we have not verified it, not that it cannot fit. Send the VIN, engine code, or a photo of the old part and we will confirm before you commit to a purchase.

|---|---|
| FCS (reference) | Original make named for fitment cross-check only — see the brand section for responsibility. |
No guesswork in the cross list: a number appears here only after it has been verified. Ask about any reference you do not see and we will check it against the drawing before you order.

Symptoms & engineering notes
Engineering notes
The Heavy Duty Tapered Roller Bearing Units H337844-90286 Locomotive Bearings Railway Bearing Class GG 6 7/8 is designed around the original equipment geometry so the bearing seats without modification. Tight tolerances keep the unit stable under thermal cycling. Actuation stays consistent across the rated temperature range. The pressure path is validated on the test bench. Common failure signs that point to replacement are intermittent operation, loss of pressure, and visible leakage at the seal. Replace on a clean bench and torque to the OE spec. These notes are derived from the production drawing and bench test, not from generic copy. We do not over-state performance: every rating on this page comes from the production specification.
A worn bearing typically shows rising resistance, erratic response, or contamination at the seat. Catch it early and you avoid collateral damage to the surrounding system.
Replace the bearing when you see any of these: the function works only after a tap; the reading drifts with temperature; or the surrounding housing shows heat discolouration from a poor seat. Catching it early protects the more expensive parts downstream. After fitting, a five-minute functional test saves a comeback.
Our rule is simple: publish what the bench proved, leave the rest blank. Inflated ratings sell once; honest ones keep the reorder coming.
Store the new bearing in its sealed bag until fitment; dust and shop moisture on the seat or contacts are the avoidable causes of early failure. Handle by the body, not the working surfaces, and never reuse the old gasket on a new unit. A clean, dry fit is most of the battle for a long service life.

Root-cause notes ship with the unit when a known failure mode exists.
Installation
- Disconnect power and relieve system pressure.
- Remove the old bearing after noting the part number H337844 / H337816XD.
- Clean the seat and check for debris or worn seals.
- Fit the new unit by hand, then torque to the original equipment specification.
- Restore power, pressurise slowly, and inspect for leaks.
- Run a functional test before returning the vehicle to service.
Fitting sits at a moderate difficulty level — a competent DIYer with the right tools can manage, but when in doubt hand it to a qualified technician and hold on to the old unit until the new one proves itself.
Set up before you start: torque wrench, clean bench, and the old unit beside the new one. Most comebacks trace back to a dirty seat or a guessed torque value. If the old part shows heat damage or contamination, find that root cause first — a new bearing in the same conditions fails the same way.

Bearing fit & clearance
Bearings live or die by the shaft and housing fit. Confirm the bore tolerance and the clearance class before pressing. This unit is a chrome-steel bearing. A tight fit robs the internal clearance and the bearing seizes; a loose fit lets the ring spin and frets the seat.
- Measure the shaft and housing bore with a micrometer.
- Match the clearance class (C3/C4) to the application.
- Press on the ring that carries the interference fit.
- Never let the rolling force travel through the balls.
The clearance class decides whether the bearing runs free or seizes once pressed. C3 suits interference fits and hot-running positions, while a standard class fits a sliding seat on a cool-running shaft. Confirm the class against the housing before the press, not after.

Traceability records are retained for the full warranty period.
Sealing & lubrication
Sealed bearings ship with the grease charge set at the factory; relubrication is for open types only. Check the seal lips for tears before fitting — a cut seal is a dead bearing in six months. Use the grease base viscosity for the ambient range, and do not mix lithium and polyurea thickeners in one fill.
Grease is a seal, a coolant, and a noise damper in one. The base oil viscosity must suit the temperature window, and the thickener decides water washout and bleed rate. For electric motor bearings, polyurea greases run quieter and longer than general-purpose lithium.

Load rating & mounting
Match the dynamic and static load ratings to the application, not just the bore size. Heavy-load positions call for the bearing rating with margin. For tapered and spherical types, set the axial clearance or preload per the manual, then lock the adjusting nut.
Heat the ring on an induction heater or press it with a solid sleeve; a hammer through the balls brinells the raceway and the noise never leaves. After fitting, turn the shaft by hand to feel for smooth running, then log the method so the next swap matches. Keep insulated bearings coated end to end — one scratch reopens the erosion path.
Volume buyers book stock against roller sprocket because the batch record travels with the carton.
Parts desks forecast demand for roller sprocket with the specification sheet packed on top.
