Reliable Differential Bearings from Yokomo BB-85-4A

The Yokomo BB-85-4A bearings are a straightforward replacement option for RC differentials needing 5x8x2.5mm parts. They are intended to reduce friction within the diff and help maintain smooth drivetrain operation.

Fit and Function

These bearings have a 5mm inner diameter and 8mm outer diameter, matching common diff specifications. Supplied as a set of four, the pack is sized to service a full differential installation.

Maintenance and Longevity

Regular inspection for rough spots or endplay will indicate when to replace bearings. Keep bearings clean and use light RC bearing oil to maximise their service life.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I know if my diff needs new bearings?

Symptoms include gritty rotation, excess lateral movement on shafts, or audible noise from the diff. Those signs point to replacement.

Is special grease required with these bearings?

Use a light bearing oil rather than heavy grease for differential bearings to keep drag low. Heavy greases can slow diff response.

Can I press these in by hand?

Small diffs can sometimes be fitted by hand, but a press or appropriate socket ensures even seating and reduces risk of damage.
