High-precision industrial cylinder with hard-anodized aluminum barrel for wear resistance. Features integrated magnet for position sensing compatibility and corrosion-resistant end caps. Designed for medium-duty applications requiring smooth operation and precise stopping accuracy through adjustable air cushions. Lubricator-free design with low breakaway pressure (≤0.08 MPa).
- Press machine ejection systems
- Conveyor gate actuators
- Automated assembly line positioning
- Plastic injection molding machine clamps
- Packaging equipment pusher mechanisms
Installation note:
Align cylinder axis with motion direction within ±1° tolerance. Use flexible couplings when lateral forces exceed 5% of max thrust. Maintain 0.1-0.3 MPa residual pressure during adjustment of cushioning screws.
