Keep Your RC Differential Rolling Smoothly with Yokomo BB-85-4A

For hobbyists wanting reliable rotation and straightforward upkeep, the Yokomo BB-85-4A ball bearings are a practical choice. These 5x8x2.5mm bearings are intended for differential use and help maintain consistent operation under normal running conditions.

Benefits for Differential Use

The Yokomo BB-85-4A features a 5mm inner diameter and an 8mm outer diameter to fit many common differential assemblies, reducing friction and supporting smoother drivetrain response. The pack contains four bearings, providing a complete set for most standard diffs.

When to Service or Replace

Replace bearings if you notice rough rotation, excess play, or noise coming from the differential. Regular checks and light lubrication will extend service intervals and keep components running predictably.
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.

Will these bearings fit my differential?

These bearings fit differentials that call for 5x8x2.5mm bearings. Confirm your model's specifications or measure the bore before ordering.

How should I prep the bearings before use?

Clean off any packing residue, then apply a small amount of light bearing oil suitable for RC use. Avoid heavy greases that can increase drag.

Any tips for installing them into the diff?

Press bearings in squarely using a bearing driver or a socket that matches the outer race. Do not hammer directly on the inner race to avoid damage.
