TAMIYA CR01 Full Bearing Upgrade BS-CR01/V1 by 3Racing  [BS-CR01/V1]

Kit summary

The BS-CR01/V1 bearing set provides running ball bearings to replace plain bushings and similar fixed-fit parts on the TAMIYA CR01 chassis. Swapping to bearings cuts friction in the drivetrain and wheel hubs, improving smoothness for scale crawling and low-speed trail use.

This item is aimed at maintenance and tuning rather than changing suspension geometry. Installed bearings reduce rotating resistance along shafts, lower rolling drag on wheels, and can help drivetrain components run cooler during extended low-speed operation.

Fitting notes: remove original bushings or pressed bearings with care, inspect mounting bores for wear and side play, and seat bearings using correct drivers. Apply light bearing oil or a recommended thin grease, then check gear mesh and wheel hex preload to ensure the CR01 parts remain within specification.

For hobbyists wanting a cleaner drivetrain feel on the CR01, BS-CR01/V1 offers a simple replacement route; practice standard bearing care to keep longevity high.
