The SI63AX275 industrial cylinder combines high moment resistance (up to 32N·m torsion load) with smooth operation (±0.5mm repeat positioning accuracy). Its dual guide rod design minimizes lateral deflection during extended stroke operations. Features a wear-resistant scraper seal system that maintains performance in environments with ISO 4406 18/16/13 class contamination levels.
- High-speed packaging line pusher mechanisms (up to 3 cycles/sec)
- Plastic injection molding machine ejector systems
- Automated welding fixture positioning
- CNC machine tool clamping devices
- Lithium battery production material handling
Installation protocol:
For vertical mounting, use counterbalance valves when handling >5kg payloads.
Maintain 0.5-1mm alignment tolerance during parallel cylinder installations.
Break-in procedure: Cycle 50 times at 0.3MPa before full-pressure operation.
