High-torque industrial cylinder designed for heavy-load automation systems. Features precision honed tube and multi-layered sealing system for ≤0.1 m³/min air leakage. The chrome-carburized piston rod provides exceptional wear resistance in high-cycle applications (≥5 million cycles at rated load). Includes magnetic piston for sensor compatibility.
- Automotive production line clamping fixtures
- Press machine ejection systems
- Foundry equipment metal casting handling
- Plastic injection molding machine core pulling
- Heavy-duty conveyor sorting gates
Installation guidelines:
Align cylinder axis within ±0.2° deviation. Use flexible couplings for
stroke-end impact reduction. Lubricate with ISO VG32 hydraulic oil
(1-2 drops per port monthly). Adjust cushioning screws gradually -
overtightening causes piston deceleration failure.
