Heavy-duty adjustable stroke cylinder with precision position locking mechanism. Features dual anti-rotation guide rods (Ø20mm) and magnetic piston for position feedback compatibility. The enhanced cushion system reduces end-impact noise by 40% compared to standard models. Requires 5μm filtered compressed air with dew point -20℃ below ambient.
- Die casting machine ejection systems
- Automotive welding fixture positioning
- Paper roll clamping in printing presses
- Plastic injection molding machine core-pulling
- Heavy conveyor gate control
Installation Guidelines:
Use M12×1.75 grade 8.8 mounting bolts (4x). Maintain 0.5mm alignment tolerance during installation.
For vertical mounting, install air vent valve at upper port. Perform stroke adjustment only in depressurized state.
- Relubricate every 500km stroke (or 6 months)
- Inspect cushion seals every 100,000 cycles
- Torque check: Rod end nuts (85-95 N·m), Mounting bolts (55-65 N·m)
