A high-duty cycle cylinder with precision honed tube and anti-rotation design. Features dual piston seals for leak-free operation and magnetic piston for position sensing compatibility. The chrome-plated rod incorporates a hardened layer (0.02-0.05mm) for scratch resistance. Requires ISO VG32 hydraulic oil lubrication when used in high-speed applications (>500mm/s).
- Automated assembly line clamping mechanisms
- Packaging machine pusher arms
- CNC machine tool door actuators
- Plastic injection molding ejectors
- Material handling transfer systems
Installation note:
Maximum side load capacity 35N. For vertical mounting, use rod-down position
to prevent piston seal wear. Lubricate through air supply (oil mist 1-2 drops/m³)
for optimal seal life. Allow 20mm clearance behind rod end for maintenance.
