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

Technical Specifications: Bore: 273.00 mm / Stroke: 318.52 mm / Weight: ~675.5 kg / Hydro-Pneumatic Suspension Cylinder

Compatible Machinery: Caterpillar 100-Ton Class Mining Off-Highway Trucks (777C, 777D, 777F, 777G series)

What It Does:

Serves as the hydro-pneumatic (oil-to-nitrogen) suspension cylinder actuator mounted between the main structural chassis and axle/wheel assemblies on Caterpillar 777 series 100-ton class off-highway mining trucks. It cushions the vehicle frame against massive payload impacts, absorbs severe ground shocks from rugged haul roads, and stabilizes the machine during full-tonnage transport operations.

Importance:

A critical structural and ride-control component essential for protecting the main truck chassis, maximizing mining tire service life, and maintaining vehicle handling and stability under extreme payload conditions. Built with a massive 675.5 kg heavy-walled barrel and a 273.00 mm bore forged structure, it effectively withstands extreme cyclic shock loads, torsional stresses, and severe haul-road impacts, while advanced heavy-duty hydro-pneumatic seals prevent gas and oil leakage to deliver consistent damping and operational reliability.
