- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Construction machinery boom control
- Plastic injection molding machine clamps
- Heavy conveyor gate actuators
Installation note:
Allow minimum 10mm clearance around cylinder body for heat dissipation.
Lubricate through air supply (ISO VG32 pneumatic oil) or use grease-packed version.
Avoid side loads exceeding 200N on piston rod.
- 10 million cycles (standard seals)
- 15 million cycles (optional high-durability seals)
- Re-lubrication interval: Every 3,000 km of rod travel
