A heavy-duty industrial cylinder featuring dual anti-rotation design and precision honed tube. The SI100X138 delivers 785N thrust force at 0.6MPa (with 85% efficiency factor). Its chrome-carburized piston rod resists side loads up to 10% of maximum thrust. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Metal stamping press ejection systems
- Plastic injection molding machine clamp units
- Automotive welding fixture positioning
- Packaging line product compression
- Foundry equipment door actuators
Installation requirements:
Maintain 0.05–0.15mm clearance between rod end and load connection.
For vertical mounting, use model with spring-opposed orientation.
Lubricate through air supply (oil mist 1–2 drops/m³).
