A heavy-duty industrial cylinder designed for high-force linear motion applications. Features corrosion-resistant construction with IP65 protection rating, suitable for harsh environments. The magnetic piston version (SI125X200-M) enables position sensing compatibility. Requires 40μm filtered air with oil mist lubrication for optimal performance.
- Automotive assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- Steel mill material handling systems
- Paper processing equipment actuators
- Warehouse automated stacking robots
Installation note:
Allow minimum 3mm thermal expansion clearance during mounting.
For vertical installations, use locknut (AN3-LK) to prevent rod rotation.
Lubricate through air supply (ISO VG32 equivalent) in dusty environments.
