Yanmar B17 Support Roller For Mini Excavator Chassis Components
To ensure that the crawler chain moves safely and reliably even under the heaviest loads, the track rollers are made particularly robust and precisely tailored to the crawler system.
Specification:
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.
