The chromium-plated piston rod provides exceptional corrosion resistance, while the external stroke adjustment mechanism allows millimeter-level positioning accuracy without disassembly. Includes wear-resistant guide bushings for side load protection.
- Variable height work platforms in assembly lines
- Press-fit operations with depth control requirements
- Clamping fixtures needing frequent stroke adjustments
- Packaging machines with product size changeovers
- Automated welding positioners requiring precise endpoint control
Operation tip:
Always lubricate the adjustment screw threads with silicone grease (AS-20) before initial use.
For optimal performance, limit maximum impact velocity to 0.5 m/s. Install a mechanical
shock absorber when using full stroke at pressures above 0.6 MPa.
