A heavy-duty ISO-compliant cylinder featuring dual anti-rotation design for precise linear motion control. The aluminum alloy construction with hard anodized surface treatment ensures corrosion resistance in harsh environments. Integrated magnet slot allows for position sensing compatibility. Low-friction seals enable speeds up to 1.0 m/s.
- Automated packaging line clamping mechanisms
- CNC machine tool door interlocks
- Automotive welding fixture positioning
- Plastic injection molding ejector systems
- Material handling conveyor gate actuators
Installation guidelines:
Maximum side load ≤15% of thrust capacity. For vertical mounting,
use rod-down orientation to prevent seal wear. Lubricate every
3,000km of cumulative travel or 6 months (whichever comes first).
Allow 20mm clearance around cylinder for heat dissipation.
