Excavator Hydraulic CylinderS Compatible Factory Direct Stock Arm Cylinder Telescopic 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 adjustments and finite element analysis (FEA), these cylinders achieve a 15–20% weight reduction while maintaining rated working pressure, thereby lowering fuel consumption and enhancing performance.
An extended guide sleeve paired with self-lubricating composite bearings absorbs lateral forces and eccentric loading moments caused by rough terrain; this prevents piston rod scoring and bending, ensuring precision in reciprocating motion and long-term coaxial alignment.
Designed for 1.5–6 ton mini-excavators, these cylinders—covering boom, stick, bucket, and swing/outrigger applications—deliver working pressures and thrust outputs comparable to large-scale equipment within compact installation spaces, meeting the exacting demands of municipal construction and indoor demolition tasks.
