A heavy-duty linear actuator designed for long-stroke industrial applications. Features dual adjustable pneumatic cushions for smooth deceleration and anti-rotation design for precise load guidance. The chrome-plated piston rod incorporates a scraper seal to prevent particulate ingress. Requires 40μm filtered air with 1-10 mg/m³ lubricant content (ISO 8573-1).
- Palletizing robot end-effector drives
- Automotive welding fixture positioning
- Textile machinery tension control systems
- Plastic injection molding ejectors
- Paper processing equipment actuators
Installation Guidelines:
Maintain 0.5mm minimum alignment tolerance between rod and load.
Use locknuts (not included) for vertical mounting. Lubricate through
air ports during initial commissioning. Allow 20mm free space
behind end covers for cushion adjustment.
