This is a replacement ProTek R/C 7x19x6mm Front Bearing. This bearing is designed to fit the ProTek R/C Samurai 321B Nitro Engine, but is also compatible with most O.S. .21 engines. This bearing will also fit any other .21 competition buggy engine that uses the same bearing dimensions; 7mm inner diameter, 19mm outer diameter and 6mm thick. This bearing is shielded only on the outside; the inside is open to allow the ball proper lubrication.


ProTek R/C is an AMain Sports & Hobbies brand.
