Part Name: Off-Highway Truck Rear Suspension Cylinder Group / Assembly

Technical Specifications: Bore: 215.90 mm / Stroke: 149.26 mm / Weight: Not Specified (Heavy-Duty Hydro-Pneumatic) / Suspension Cylinder

What It Does:

Serves as the hydro-pneumatic (oil-to-nitrogen) rear suspension cylinder actuator mounted between the main chassis frame and the rear axle assembly on Caterpillar 773 and 775 series rigid off-highway trucks. It cushions and isolates the truck frame from severe ground shocks, absorbs road surface irregularities, and supports extreme payload tonnage during loading and haulage operations.

Importance:

A critical structural and ride-control component essential for protecting the truck chassis frame, extending tire service life, and maintaining vehicle stability under full mining payloads. Engineered with a massive 215.90 mm bore heavy-walled barrel and forged rod construction, it effectively withstands immense vertical shock loads, torsional forces, and harsh haul-road impacts, while advanced heavy-duty hydro-pneumatic seals prevent gas and fluid leakage to ensure consistent damping performance.
