High-force industrial cylinder designed for heavy-duty automation applications. Features corrosion-resistant construction with double piston seals for leak prevention. The 125mm bore provides exceptional pushing force for large mechanical systems, while the chrome-plated rod ensures durability in high-cycle operations. Requires 40μm filtered air and regular lubrication for optimal performance.
- Press machine ejection systems
- Automotive welding fixture positioning
- Plastic injection molding machine core pulls
- Heavy conveyor gate actuators
- Foundry equipment operation
Installation note:
Allow minimum 5mm lateral clearance for thermal expansion. Use locknuts with 50-60Nm torque for mounting.
For vertical installations, implement anti-drop mechanism (notch pin or safety clamp).
