A high-duty pneumatic cylinder featuring precision honed tubing and dual anti-rotation guides. The SI63X25H's enhanced rod bearing design reduces lateral play to ≤0.3mm, making it ideal for precision pushing/pulling applications. The H-mount configuration provides 4×M6 threaded holes (depth 10mm) for secure mounting in high-vibration environments.
- Carton sealing machine compression units
- CNC tool changer positioning mechanisms
- Automotive welding fixture clamping
- Conveyor gate actuators in food processing
- Plastic injection molding ejector systems
Installation protocol:
For vertical mounting, use counterbalance valves when handling loads >5kg.
Lubricate rod every 500km stroke travel using ISO VG32 hydraulic oil.
Avoid side load exceeding 15% of maximum thrust capacity.
