Tamiya 15475 JR 13mm Roller Ball Bearings Set II - 2pcs, durable mini 4WD upgrade  [15475]

Product brief for Tamiya 15475 Roller Ball Bearings Set II

The Tamiya 15475 Roller Ball Bearings Set II is a compact upgrade for Mini 4WD fans wanting reduced rolling resistance. Included are two 13mm steel roller bearings made to improve wheel spin smoothness and stability during races. The sturdy material selection helps ensure consistent performance over repeated runs.

Design purpose and fitting notes

These bearings are intended to lower friction where wheels meet axles, improving drive efficiency and responsiveness. When installed they help the car maintain speed and handle transitions more predictably. Their dimensions are broadly compatible with many common Mini 4WD configurations, but always double-check spacers and axle clearance during fitment.

Race day benefits and upkeep advice

Using the Tamiya 15475 bearings reduces wear on rubbing surfaces and can extend the useful life of wheels and axles. Regular cleaning and light lubrication will keep them rolling freely and help avoid premature failure during competitive use.
