Keep your differential running smoothly with Yokomo BB-850PA

The Yokomo BB-850PA is a precision bearing designed to reduce internal friction and limit drive loss in RC differentials. With a 5mm inner diameter and 8mm outer diameter at 2.5mm width, this 5x8x2.5mm part supports steady rotation in many small-scale RC drivetrains.

Practical benefits for track and hobby use

These bearings are suited to modelers seeking consistent handling and less drivetrain drag. Fitting Yokomo BB-850PA bearings can improve roll consistency and contribute to predictable throttle and steering input on both practice runs and race day.
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 they fit my gearbox housing?

They fit housings designed for 5x8x2.5mm bearings. Confirm the bore size and width in your model manual to ensure correct installation.

What lubricant should I use?

Use a light bearing oil or a thin synthetic grease suitable for small bearings. Avoid heavy greases that can increase drag in small-diameter bearings.

How often should I replace them?

Replace when you detect rough movement, increased noise, or visible wear. Regular inspection after wet or dirty runs helps spot issues early.
