Precision Bearings for Cleaner Drivetrain Action

Quality bearings help maintain power transfer and reduce wear. The Yokomo BB-1812 12x18x4mm ball bearings are crafted to lower friction in the drivetrain and are commonly fitted to the front and rear sections of B-MAX4 and D-MAX slipper clutch systems.

Exact Size and Fit

With a 12mm bore and an 18mm outer ring, these bearings are manufactured to tight tolerances to ensure a correct press fit. Proper fit reduces vibration and keeps rotating components tracking true.

Ready for Service

Provided as a matched pair, this set supplies both sides of a slipper clutch. Fresh bearings can restore responsiveness and reduce mechanical drag, improving handling consistency across different track 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.

Do these bearings require bedding in after installation?

A short run-in period under light power helps seating and removes any minor imperfections. Check for smooth rotation and re-check fit after the first few runs.

How can I spot a failing bearing?

Look for increased noise, rough rotation, play on the shaft, or visible rust. Any of these signs indicate the bearing should be serviced or replaced.

Is it safe to run these bearings without seals?

Running without seals can be acceptable in clean conditions to reduce drag, but seals protect against dirt and moisture. Choose based on your typical running environment.
