High-precision industrial cylinder featuring wear-resistant chromium plating and dual-sensor slots for magnetic switch compatibility. Optimized for medium-duty cyclic operations with its buffered stroke control and anti-rotation piston rod. Requires ISO VG32 hydraulic oil lubrication if used in low-speed applications (<100mm/s).
- Automated assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- CNC machine tool door actuators
- Food processing conveyor gate controls
- Palletizing robot end-effector positioning
Installation notes:
- Align within 0.2mm perpendicularity tolerance during mounting
- Use flexible couplings for lateral force compensation
- Maintain 1.5mm minimum clearance around magnetic sensors
- Lubricate through air supply (ISO VG32 oil mist, 1-2 drops/m³)
- SI-MD10N magnetic proximity sensor (sold separately)
- SI-BK04 adjustable cushion needle valve kit
- SI-RJ20 rod jam protection sleeve
