High-capacity industrial cylinder featuring precision honed tubing and dual anti-rotation guide rods (optional). The SI125AX350S combines 20% increased lateral load capacity compared to previous generation models through reinforced end caps. Requires 40μm filtered compressed air with dew point -20℃ below ambient. Features integrated magnetic sensor slots (M9 connector compatible) for position feedback.
- Automotive production line clamping fixtures
- Die-casting machine core-pull mechanisms
- Paper roll handling systems
- Plastic injection molding ejectors
- Steel coil lifting/lowering actuators
Installation guidance:
Maintain 0.05-0.15mm clearance between piston rod and guide when using slide units.
For vertical mounting, install air vents upward. Maximum side load: 380N at mid-stroke.
- SI-MF12N magnetic sensor kit
- SI-TF125 adjustable auto switch bracket
- SI-AC125 rod-end spherical joint
