Tamiya 15475 JR 13mm Roller Ball Bearings Set II - Pair for Mini 4WD racers  [15475]

Summary of the Tamiya 15475 Roller Ball Bearings Set II

The Tamiya 15475 Roller Ball Bearings Set II gives Mini 4WD builders a straightforward upgrade to reduce drivetrain drag. This pack contains two 13mm steel roller ball bearings engineered to support smoother wheel rotation and better stability through both technical corners and long straights. The robust steel construction helps keep the bearings running reliably over many race days.

How these bearings perform and fit

Designed to cut friction in rolling components, these bearings help the car maintain speed with less power loss. When fitted correctly they improve handling and responsiveness, especially on high speed sections. Their common sizing makes them suitable for a broad range of Mini 4WD chassis and wheel setups used in club and track builds.

Benefits for maintenance and longevity

Using the Tamiya 15475 bearings can reduce wear on axle and wheel contact areas, leading to longer service intervals. The reduced friction also means less heat and slower part degradation, which benefits both casual hobbyists and regular racers wanting consistent performance without constant rebuilds.
