The SI40X125S medium-duty pneumatic cylinder features precision honed tubing and double O-ring seals for leak-free operation. Its integrated magnetic piston enables position sensing compatibility. The anodized barrel resists corrosion in humid environments, while the chrome-plated rod withstands side loads in misalignment scenarios. Optional auto-switch grooves (SI-MQSM series) can be added for feedback control.
- Automated conveyor gate actuators
- CNC machine tool clamping mechanisms
- Plastic injection molding ejectors
- Automotive assembly line positioning
- Food packaging vertical lift systems
Installation tip:
Maintain 0.5-1mm clearance between rod end and load during alignment.
Lubricate with ISO VG32 hydraulic oil if operating below 2℃.
For vertical mounting, use rod-down orientation to prevent seal wear.
