The SI40BX110 medium-duty industrial cylinder features precision honed tubing and enhanced rod bearing design for smooth linear motion. With 25% increased lateral load capacity compared to previous generations, it maintains stable performance under misalignment conditions. The triple-seal structure ensures leak-free operation even in high-cycle applications (up to 3 million cycles).

- Packaging machine pusher arms
- CNC machine tool door interlocks
- Plastic injection molding ejectors
- Automotive welding fixture positioning
Installation tip:
For vertical mounting applications exceeding 0.5 MPa, install a mechanical stop to prevent piston rod rotation. Maintain 0.5–1 mm alignment tolerance during mounting. Use locknuts with 15–20 N·m torque for rod-end connections.
