Key Engineering Features

Robust Construction: The front and back covers are connected to the stainless steel tube using a riveted rolling packed structure, ensuring a reliable, leak-proof connection even under high-cycle operations.
Advanced Piston Design: Utilizes a heterogeneous two-way seal structure that allows for a compact size while providing an integrated grease reservation function for extended service life.
Precision Cushioning: Equipped with an adjustable air cushion to suppress vibration and noise at the stroke ends, reducing mechanical impact on the machine frame.
High Strength Body: The cylinder tube is made of high-precision stainless steel, offering high rigidity and excellent resistance to harsh industrial environments.
Installation Flexibility: The swivelling tail type (rear eye mounting) combined with multiple back-cover modes facilitates easy integration into various mechanical layouts.
