High-performance ISO cylinder featuring precision-machined components and multi-layer seal system. The SI80 series delivers 20% higher thrust force compared to DIN standard cylinders through optimized flow path design. Integrated magnetic slot (STC version) enables position feedback with compatible sensors. Anti-rotation design maintains orientation stability during long strokes.
- Automated assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- Steel coil handling systems
- Packaging machine vertical lifters
- Automotive welding fixture positioning
Installation guidelines:
Lubricate with ISO VG32 hydraulic oil if using non-lubricated air.
Maximum side load: 150N at mid-stroke.
For vertical mounting, add mechanical lock at stroke ends.
