Precise Rotation with Yokomo BB-74-2A Bearings

If you want more consistent wheel and gearbox motion, the Yokomo BB-74-2A ball bearings are a practical swap. These 4x7x2.5mm metal bearings are made to match the tolerances of various Yokomo chassis and improve rotational accuracy.

Where These Bearings Work Best

The BB-74-2A suit chassis like MRTC-BD919 and MRTC-BD10 series, making them useful for track days and rougher off-road use when maintained properly. They are a simple way to refresh drivetrain parts.

Installation Notes and Upkeep

Before fitting, remove old grease and debris to ensure a true seating surface. Regular cleaning and occasional relubrication will prevent premature wear and keep runs smooth.
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.

Are these bearings suitable for off-road use

They are standard metal bearings that work for many off-road situations if you clean and relube them more often. For very dirty tracks consider additional shields or seals.

What tools are best for popping bearings out

A bearing puller or a small press is safest. Avoid levering against the inner race to prevent race damage that leads to rough running.

Can these replace worn stock bearings directly

If the stock parts use 4x7x2.5mm bearings, they can be direct replacements. Verify shaft and housing tolerances before fitting to ensure correct seating.
