Yokomo BB-85-4A 5x8x2.5mm Differential Bearing Set (4 pcs)  [BB-85-4A]

Smooth Diff Performance with Yokomo BB-85-4A Bearings

The Yokomo BB-85-4A ball bearings provide dependable rotation for RC differentials and straightforward maintenance. Sized at 5x8x2.5mm, these bearings are aimed at standard diff applications to reduce friction in the drivetrain.

Why Fit These Bearings

With a 5mm bore and 8mm outer diameter, the Yokomo BB-85-4A bearings fit many common diff housings to improve wheel response and lower mechanical resistance. This four pack gives you the parts needed to service a complete differential assembly.

Practical Maintenance Notes

Inspect bearings periodically for roughness or side play and replace as needed. A light drop of bearing oil keeps them spinning freely and helps avoid premature wear in the diff.
