Excavator Hydraulic Cylinder Assemblies Sizes 55 60 65 75 80 Boom Cylinder Stick Cylinders 

Product  Description

Our excavator hydraulic cylinders are high-quality aftermarket replacements designed for booms, sticks, and buckets. They feature a robust contamination-resistant sealing system—combining multi-stage dust seals with primary seals—to minimize the risk of premature seal wear and extend service life.
Constructed from high-strength alloy steel and optimized through wall-thickness refinement and finite element analysis, these cylinders achieve a 15–20% weight reduction while maintaining rated operating pressure, thereby lowering fuel consumption and enhancing performance.
An extended guide sleeve paired with self-lubricating composite bearings absorbs lateral forces and eccentric load moments caused by rough operating conditions; this prevents scoring and bending of the piston rod, ensuring precision in reciprocating motion and long-term coaxial alignment.
