The SI50AX40S features a precision-ground stainless steel piston rod with chromium plating (3-5μm thickness) for enhanced corrosion resistance. Its dual-seal design combines a primary lip seal with secondary wiper seal to prevent particulate ingress. The cylinder incorporates a wear-compensation system maintaining ≤0.5mm play throughout its 5,000km service life (under 0.5MPa).
- Automated packaging line pusher mechanisms
- CNC machine tool clamping/unclamping systems
- Automotive welding fixture positioners
- Plastic injection molding ejectors
- Food processing conveyor gate actuators
Installation Guidance:
Maintain 0.05–0.15mm radial clearance between rod and bushing. Lubricate with ISO VG32 hydraulic oil during assembly. For vertical mounting, install rod-end down to prevent condensate pooling. Maximum side load: 35N at full extension.
