High-precision adjustable stroke cylinder with rugged construction for industrial automation. Features dual-position locking mechanism for stroke adjustment (±2mm repeatability) and corrosion-resistant anodized surfaces. The 20S variant includes magnetic piston for position sensing compatibility. Requires ISO VG32-grade lubricant for optimal performance.
- Variable height positioning in packaging lines
- Press machine stroke control systems
- Automated warehouse stacker cranes
- Plastic injection molding ejectors
- Solar panel angle adjustment mechanisms
Installation guidance:
Ensure perfect axial alignment during mounting. Apply low-viscosity lubricant
(ISO VG32 equivalent) to rod before initial operation. Avoid exceeding 0.9 MPa
pressure with full stroke applications. Use rod end support when stroke length
exceeds 500mm.
