The Tamiya 15393 JR Steel Bearing set gives Mini 4WD hobbyists a straightforward path to better drivetrain efficiency. These 620-size steel bearings carry a fluorine coating to cut friction and extend service life, making them a sensible upgrade for competitive tuning.

Fit, sizing and chassis notes

Made in the 620 dimension, these bearings sit in most Mini 4WD wheel hubs and axles. They work with a wide range of chassis types, including MS, MA and AR, so installing them into your current build is usually hassle free.
