High-precision industrial cylinder with integrated magnetic sensor slot (SI series feature), designed for heavy-duty cyclic operations. Features corrosion-resistant construction and dual anti-rotation design for stable linear motion. Requires 40μm filtered air with ISO VG32 hydraulic oil mist lubrication (optional oil-free operation).
- Automated material handling systems
- Plastic injection molding machine ejectors
- Automotive assembly line positioning
- Packaging machinery actuation
- Press tooling applications
Installation note:
Maintain proper alignment with guided rail systems when handling lateral forces.
Recommended 0.5mm minimum clearance between magnetic sensor and cylinder body.
Lubricate through air supply at 1 drop/m³ for optimal seal life.
Max side load capacity: 220N (static), 130N (dynamic).
Avoid exceeding 0.9m/s piston speed without additional cushioning adjustment.
