Bottom roller fits Volvo ABG 7820 asphalt paver aftermarket undercarriage part
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 track. Forged from deep hardened steel, they are heat treated for increased internal strength to resist bell-mounting and improve rebuildability. Heat-treated outer shells provide increased body strength and longer life.
