A21900A0M00 Track roller for construction machine chassis component

Introduction:

Track rollers, also known as lower or bottom rollers, are designed to transfer most of the machine's weight and dynamic forces to the ground through the tracks. Forged from deep hardened steel, they are heat treated to increase internal strength to resist bell-mounting and improve rebuildability. Heat-treated housings increase body strength and extend service life.
