Precision Diff Bearings: Yokomo BB-85-4A

The Yokomo BB-85-4A ball bearings are intended for differential use in RC cars and are sized at 5x8x2.5mm. They help keep rotational parts turning smoothly and reduce unnecessary friction in the drivetrain.

Key Fit Details

These bearings provide a 5mm ID and an 8mm OD to match many common diff housings and axle fittings. Supplied as a set of four, they are suitable for servicing the differential assembly in most models that require this size.

Care and Inspection Advice

Check bearings periodically for noise or feel of rough spots when spinning. Clean and apply a light bearing oil as needed to prolong life and maintain smooth diff operation.
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.

Do these bearings fit vintage and modern diffs?

They fit any differential designed for 5x8x2.5mm bearings. Always verify the bore and housing dimensions on older models before fitting.

How often should bearings be serviced?

Service intervals depend on use, but inspect bearings after heavy runs or every few maintenance sessions. Regular checks prevent damage to other diff components.

Are there installation precautions to follow?

Ensure bearings are pressed in straight and evenly. Avoid striking the inner race and clean the seating surfaces before installation to ensure proper fit.
