Volvo ABG 6820 Track roller crawler 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.
Features:
This bottom roller is a durable undercarriage replacement part for your machine.
Our rollers utilize special high-strength-hardened steel and quality seal groups that provide excellent lubricating oil retention.
Sealed bearings stop dirt, mud, and grime from penetrating inner components.
It was designed and manufactured to exact OEM specifications using high-quality, high-strength steel.
It will provide long-lasting and dependable performance even if you operate in the most extreme conditions.
