The Jazrider JR-CBR-TM-056 metal shielded ball bearing set is designed as a no-nonsense service kit for TAMIYA DN-01 and TRF201 chassis. It provides the common bearing sizes used at steering, gearbox, and wheel locations so hobbyists can replace worn parts with minimal fuss.
This kit groups bearings that map to the typical wear points on the chassis, allowing targeted refreshes rather than full component swaps:
Use a drift or socket to press bearings in squarely, confirm there is no axial play, and add light lubricant after fitting. Regular checks and light servicing will keep the bearings functioning reliably in everyday use.
Jazrider supplies this set with the practical hobbyist in mind: straightforward parts, simple care, and durable metal shields to help reduce contamination from normal RC running.
