The SI40X127S features precision honed tubing and chrome-plated piston rod (18μm thickness) for smooth operation in high-cycle applications. Its modular design allows integration with magnetic switches (e.g., S-50-6PK) and position locks. The cylinder body undergoes 1.5MPa pressure testing for leak prevention.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejection systems
- CNC machine tool fixture actuation
- Food processing conveyor gate controls
- Automotive welding jig positioning
Installation guidelines:
Maintain 0.05mm maximum misalignment during mounting. Use flexible couplings
when lateral forces exceed 15N. For vertical installations, implement
speed control below 300mm/s to prevent piston slam. Replace seals after
2,000km cumulative stroke distance.
