Overview
The 220x270x24mm Ultra Light Series Deep Groove Ball Bearing 6844 C3 for Mining Vibrating Screen belongs to our Bearing range and is stocked for same-day wholesale dispatch. Buyers choose this bearing for its OE-grade build . Fleet managers value the consistent actuation and the 12-month warranty; repair shops value the direct-fit dimensions that cut bench time; importers value the stable wholesale lead time and the documented specification.
What you read here is the same specification our bench checks against: figures are measured, recorded, and published as-is, and any value the line has not verified is simply left blank. That is the standard the whole Bearing range is held to.

Technical specification
Supplied brand: Vidishi Auto.
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.
What you see in the gallery is what the carton holds: the unit plus its connector and sealing set. Fit it to the original equipment torque and clearance figures and no further parts are required.
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 6844-b22a70 before purchase. This bearing fits the applications in our fitment list. 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 | 6844-b22a70 |
|---|---|
| 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 6844-b22a70 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 6844-b22a70 against the old stamping before the wrench moves.
We would rather say “unverified” than guess. If your application is not listed, send the engine code or the old stamping and we confirm fitment first — the answer arrives before the order does.

Symptoms & engineering notes
Engineering notes
The 220x270x24mm Ultra Light Series Deep Groove Ball Bearing 6844 C3 for Mining Vibrating Screen 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.
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.
Verified details from supplier and reference listings: The 6844 is a single-row deep groove ball bearing in the ultra-light 68 series with bore 220 mm, outer diameter 270 mm and width 24 mm.. Its basic dynamic load rating is 84000 N and the basic static load rating is 107000 N with C3 clearance.. Reference speeds are 1900 rpm with grease lubrication and 2400 rpm with oil-bath lubrication.. The bearing uses chrome steel GCr15 rings and balls and is dimensionally interchangeable with SKF 61844 and FAG 61844.. Deep groove ball bearings mainly carry radial loads and can also take axial loads in both directions.. Bearings of this size suit large electric motors, heavy gearboxes and mining vibrating screens..

Installation
- Disconnect power and relieve system pressure.
- Remove the old bearing after noting the part number 6844-b22a70.
- 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.

FAQ
Is 6844-b22a70 an original part?
No. The 220x270x24mm Ultra Light Series Deep Groove Ball Bearing 6844 C3 for Mining Vibrating Screen is a compatible replacement supplied under Vidishi Auto, not a genuine original product. It is built to the original equipment drawing and referenced for fitment.
What is the warranty on this bearing?
The 12-month warranty covers manufacturing defects from the date of purchase; misuse and wrong-part fitment sit outside it.
How do I confirm fitment for 6844-b22a70?
Two checks settle it: the number on the old part and the code on the engine plate. Send both on WhatsApp and the desk confirms fitment at no charge.
Can I order this bearing wholesale?
Yes. MOQ is 2 pieces and tiered pricing applies for bulk orders.
What material is the 220x270x24mm Ultra Light Series Deep Groove Ball Bearing 6844 C3 for Mining Vibrating Screen made from?
It uses OE-grade materials for durability.
Do you provide the connector and seals?
Included: the connector and the sealing set you see in the gallery photos, packed with the unit.
What about shipping cost and insurance?
Freight is quoted to your destination port with the landed option; cargo insurance can be added to the quote.
How long is the lead time?
If it is on the shelf it leaves the same day. Custom and volume orders get a fixed date on the quotation, not a vague promise.

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.

Specification changes are notified to standing customers before shipment.
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.

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.
Workshops standardise on bearing assembly so warranty claims stay simple.
Trade counters book stock against bearing assembly so the shelf never dips before the reorder lands.
Distributors forecast demand for bearing assembly and confirm the reference at dispatch.
Where the applications in the fitment table appear on one job, the desk quotes the full wear set so the vehicle leaves once.
Reference 6844-b22a70 carries the same warranty terms as the rest of the Vidishi Auto wholesale range. Batch 0496604C.
