The SI50AX85 features a robust aluminum construction with precision-machined components for smooth operation in repetitive industrial applications. Its double-sealed piston design ensures minimal air leakage, while the chrome-plated piston rod provides excellent corrosion resistance. The cylinder incorporates wear-resistant guide rings that extend service life in side-load applications.
- Material handling systems requiring medium-force linear motion
- Packaging machine clamp positioning
- Automated assembly line part ejection
- Textile machinery tension control
- Plastic injection molding machine gates control
Installation recommendation:
Use alignment couplers when mounting to prevent side load stress.
Lubricate with ISO VG32 hydraulic oil if operating in high-cycle
applications (>500,000 cycles/year). Maintain 0.3-1.0 MPa air
pressure for optimal seal performance.
