Bottom Roller A21900A0M00 For Wirtgen Milling Machine Undercarriage Part
Description:
To ensure that the crawler unit chain can move safely and reliably even under the heaviest loads, the rollers are made particularly robust and precisely tailored to the crawler unit system. 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.
