Excavator parts B70-2 Track roller

The Yanmar B70-2 track roller is an important part of the undercarriage system of the Yanmar B70-2 mechanical equipment (such as excavators, etc.). It mainly plays the role of supporting the weight of the equipment, transferring the gravity of the equipment to the ground and rolling on the guide rails or track plates of the tracks. Yanmar B70-2 support wheels are usually made of wear-resistant materials to cope with harsh working environments and strong impacts. Its rim design effectively prevents lateral movement of the tracks, avoiding equipment derailment during traveling and steering. In addition, good sealing is also an important feature of this supporting wheel, which can prevent mud, water and other impurities from entering into the interior, reduce the wear of internal parts, and ensure the normal operation and service life of thetrack roller.
