RC-grade ceramic bearings for consistent roll

The Yokomo BB-850CB ceramic ball bearings are a compact solution for 1/10 scale cars needing reliable rotation parts. They measure 8mm outer diameter, 5mm inner diameter and 2.5mm thick to match standard small-scale bearing seats.

Benefits of ceramic construction

Ceramic balls resist wear and cope with higher temperatures more readily than steel, which reduces operating friction and prolongs service life. That makes them a practical choice for performance-focused maintenance and tuning.

Installation tips and use cases

Replace worn bearings with BB-850CB units in wheels, diffs and motor mounts to improve free-rolling behaviour. Clean the housings, confirm tolerances and apply light lubrication to achieve the best results.
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 check bearing fit?

Measure both bore and shaft diameters and compare to the 5x8x2.5mm specification; press fits should be snug but not forceful to avoid cage damage.

Can I use them in wet conditions?

Ceramic material resists corrosion better than steel, but water and grit still shorten life. Use sealed setups or re-lubricate promptly after wet runs.

Do they need to be broken in?

A short bedding-in period under light load helps seating and removes any minor surface residues. After that, regular light maintenance keeps them in top condition.
