CAT 095-9772 SEAT-SPRING

CAT 095-9772 (0959772) is a track tensioning cylinder spring seat adapted for the 760GT tracked chassis. It is a cup-shaped cast steel structure with positioning steps, compatible with models such as 349/352/374/395 excavators and 982/988 loaders. Installed between the 095-9760 spring base and the 095-9732 main compression spring, it positions the spring, transmits axial load, limits radial spring offset, and ensures stable operation of the track tensioning system.

Compatible Models: CAT 349, 352, 374, 395 excavators; 982, 988 loaders (760GT tracked chassis configuration)
Functional Positioning: Positions the 095-9732 main compression spring, transmits axial load, limits spring radial offset, ensures spring coaxiality, distributes load to the 095-9760 base, and protects the inner wall of the cylinder.
Adaptation and Application:
Installation Position: Inside the track tensioning cylinder, placed on the positioning step of the 095-9760 spring base. The upper end supports the 095-9732 main compression spring, and the lower end fits against the base. It works in conjunction with the 095-9643/095-9665 retainer to transmit tension force, forming a closed-loop load transmission system.

Application Scenarios: Heavy-duty operations such as mining stripping, rock crushing, and tunnel excavation. It withstands high-frequency impacts and alternating loads from the 095-9732 spring, preventing spring eccentricity from causing scratches on the cylinder’s inner wall. Suitable for high-intensity working environments (Cat).

Core Functions: Positions the spring and transmits axial loads, limits radial spring offset, ensures spring coaxiality, distributes loads, protects critical cylinder components, maintains stable track tension, and reduces the risk of tensioning system failure.
