The anodized aluminum construction with chrome-plated piston rod ensures corrosion resistance in humid environments. Integrated magnetic piston enables position sensing compatibility.
- Precision clamping fixtures in CNC machining centers
- Variable height positioning in automated packaging lines
- Gate control in injection molding machines
- Workpiece ejection systems with adjustable force
- Printing press roller engagement mechanisms
Installation tip:
Use locknuts (not included) on the adjustment screw after setting desired stroke length.
Lubricate with ISO VG32 hydraulic oil before initial operation. Maintain 0.3-1.0 MPa
filtered air pressure for optimal cushioning performance.
Critical note:
The 20S variant requires monthly re-lubrication when used in high-cycle
applications (>500 cycles/hour). Avoid side loads exceeding 30N to prevent rod bending.
