High-torque long-stroke pneumatic cylinder engineered for heavy-duty linear motion applications. Features precision honed tubing and triple-lip rod seal for reliable operation in high-cycle environments. Requires 5-40μm filtered compressed air with ISO 8573-1:2010 Class 3 air quality.
Typical Applications:
- Automotive assembly line lifting mechanisms
- Steel coil handling equipment
- Plastic injection molding machine ejectors
- Warehouse vertical conveyor systems
- Paper mill roller positioning

Cycle optimization:
For maximum lifespan at full 900mm stroke, limit to 60 cycles/minute.
Add external shock absorbers when stopping accuracy < ±2mm required.
