Cat® grease lubricated undercarriage track link with 37 joints
Description
Cat Undercarriage System Track Joint Using 37 Grease Lubrication Description:
A track joint is an undercarriage component that connects the track shoes of a continuous track, allowing the vehicle to travel over uneven terrain. The track link group consists of parts such as cotter pins, track bushings, track master bushings, track links, track pins, master pins, and seals. The pins and bushings allow the joints to rotate and articulate relative to each other, enabling the track to conform to uneven ground and maintain traction.
Features
- Pins and bushings are sealed against dust and dirt and lubricated with grease to reduce wear.
- Reduces undercarriage noise and lowers the risk of joints freezing or seizing.
- Withstands high loads and stresses during operation.
Applications
Track joints are used to provide better traction and stability for the movement of the track group in the undercarriage system, and are most commonly used on Cat 312 OEM applications and 307, 307.5, 307B, 307C, 307D, and 307E Excavators.
