Long-Life Bearings Built for RC

For consistent performance and longevity you need bearings you can trust. The Yokomo BB-1812 12x18x4mm ball bearings help cut friction in drivetrains and are commonly used in the front and rear sections of B-MAX4 and D-MAX slipper clutches.

Accurate Dimensions

With an 18mm outer diameter and a 12mm inner diameter, these bearings are produced to close tolerances to ensure a snug installation. That dimensional accuracy reduces play and improves rotational stability.

Where to Use Them

This two-piece set gives you the bearings required for both ends of a slipper clutch assembly. By lowering internal resistance they can sharpen throttle response and make handling feel more direct on all surfaces.
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.

Can I swap these into other slipper clutch systems?

Yes. Any slipper clutch designed for 12x18x4mm bearings will accept Yokomo BB-1812 units, provided there is no interference from hub geometry or seals.

What lubricant is best for these bearings?

A light, low-viscosity bearing oil or thin grease made for RC bearings is suitable. Avoid heavy grease that can add drag in high RPM applications.

How often should I replace them?

Replacement interval depends on use and exposure to dirt or water. Check bearings regularly and replace if you notice roughness, play, or noise during runs.
