High-force industrial cylinder designed for heavy-duty automation applications. Features corrosion-resistant construction with ISO-standard mounting patterns for easy integration. The magnetic piston version (SI125X170-M) enables position sensing compatibility. Requires 5-40μm filtered air with oil mist lubrication (ISO VG32 recommended).
- Automotive production line clamping fixtures
- Steel mill material handling systems
- Plastic injection molding machine ejectors
- Paper processing equipment actuators
- Construction machinery hydraulic assist systems
Installation guidelines:
Use flexible couplings to prevent side load misalignment.
For vertical mounting, install rod-down orientation with
50% reduced max speed to prevent piston slam.
Lubricate through air supply (0.3-0.5g/m³ oil content).
