High-precision industrial cylinder featuring dual anti-rotation guide slots and wear-resistant anodized surfaces. The SI40X25's tapered air cushion design reduces end-impact noise to below 75dB while maintaining 0.01mm repeat positioning accuracy. Optimized flow paths achieve 20% faster response times compared to previous generation models.
- High-speed pick-and-place systems (cycle time <0.5s)
- Precision clamping fixtures for CNC machining centers
- Printing press paper feed mechanisms
- Automated pharmaceutical blister packaging lines
- Battery module assembly presses
Installation guidelines:
Lubricate with ISO VG32 hydraulic oil before initial use. Maintain 0.3-0.5mm alignment tolerance during rod-end mounting. For vertical installations exceeding 45° angle, use auxiliary support brackets (ASB-40 accessory recommended).
