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.
Every unit passes a pre-dispatch check before it is packed: response at the rated condition, a pressure or flow confirmation where the specification requires it, and a visual inspection of the seal and connector. A unit either passes and gets stamped or it is pulled from the batch. Shipping untested stock saves nothing when the unit comes back.

Fitment
Fitment verification
Confirm the engine code plate and the part number 801320.H182, 801320, 801321 before purchase. This bearing fits the applications in our fitment list. Reference model: 801320.H182. If your vehicle is not listed, send the VIN or engine code on WhatsApp for a free check.
Lay the new unit next to the old one before fitting — the casting marks, the connector keyway, and the mounting holes have to line up. A near-miss revision will fight the seat and can take the surrounding circuit with it.
| Part number | 801320.H182, 801320, 801321 |
|---|---|
| Reference model | 801320.H182 |
| 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 801320.H182, 801320, 801321 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 801320.H182, 801320, 801321 against the old stamping before the wrench moves.
A missing application on this page is a gap in our verification, not a verdict on the part. Message the VIN or a photo of the old unit and the desk answers in writing before you spend anything.

Symptoms & engineering notes
Engineering notes
The Heavy Load 801320.H182 Train Tapered Roller Bearings Railway Bearing 801320 801321 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.
Typical signs the bearing is finished: intermittent function that clears after a tap, a reading that wanders as the temperature changes, or heat marks around the seat pointing to a poor connection. Swap it at the first sign and the downstream parts stay protected; a five-minute check after fitting keeps the comeback away.
No figure on this page was borrowed from a competitor catalogue. If the line has not verified a value, the field stays blank — professional buyers can audit every number we publish.
Leave the new bearing sealed until the bench is ready. Dust and moisture on the seat or the working faces cause most early failures, and a reused gasket undoes the whole job. Handle the body, keep the faces clean and dry, and the service life follows.

Repeat failures usually point to a wiring or heat issue nearby.
Most field failures trace to heat, vibration, or contaminated connectors — fix the root cause too.
Installation
- Disconnect power and relieve system pressure.
- Remove the old bearing after noting the part number 801320.H182, 801320, 801321.
- 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.
Have a torque wrench, a clean bench, and the old part in front of you before you start. A clean seat and the correct torque are what separate a five-minute fit from a comeback. If the old unit shows heat or contamination, fix that root cause or the new bearing will fail the same way.

Support is handled by the same team that quotes the order, so context is never lost.
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.
Clearance class is the number buyers overlook. C3 gives extra internal clearance for hot or interference-fit mounts, and railway and vibrating-screen housings usually call for it. Measure the seat before you order the fit, not after the bearing is pressed.
Export agencies hold shelf space for sprocket roller because the batch record travels with the carton.
Wholesale partners book stock against sprocket roller with the specification sheet packed on top.
Service centres forecast demand for sprocket roller because a documented spec shortens receiving-line QC.

Revision history for the drawing is available to auditors.
Batch records for this unit type are retained for traceability audits.
Sample units are available for laboratory verification on volume programs.
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.
Garage groups consolidate orders for heavy load railway bearing so the shelf never dips before the reorder lands.
Volume buyers quote volumes for heavy load railway bearing so the fitter works to torque values rather than habit.
Parts desks standardise on heavy load railway bearing to cut diagnostic time on repeat failures.
Questions about Bearing fitment on the applications in the fitment table are answered by the engineer who approved the drawing, not a script.
Stock cover for 801320.H182, 801320, 801321 is planned against your last three order cycles, so the shelf holds until the next lands. Batch 5351F574.
Standing customers see demand notes before spot buyers.
Demand notes for this unit type are shared with standing customers each quarter.
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.
Mount with an induction heater or a press and a solid sleeve — never hammer the ring. After fitting, rotate by hand to confirm smooth running, then record the mounting method on the job card so the replacement follows the same steps. Insulated bearings go in with the coating intact; a scratched coating defeats the whole purpose.
Trade counters hold shelf space for train horn and confirm the reference at dispatch.
