The SI40AX90S is a medium-duty double-acting cylinder featuring precision honed tubing and hardened piston rods. Its 40mm bore delivers 502N thrust at 0.5MPa (72.5psi), with magnetic versions available for position sensing. The enhanced cushioning system reduces end-impact noise by 15dB compared to basic models.
- Automated palletizing systems (box positioning)
- Plastic injection molding ejectors
- CNC machine tool clamping mechanisms
- Automotive assembly line pushers
- Food processing conveyor diverters
Maintenance protocol:
Lubricate rod weekly with ISO VG32 hydraulic oil. Avoid side loads exceeding 15N·m.
For vertical mounting, install speed controller on lower port.
Critical note:
Requires 5-40μm filtration. Never exceed 100% duty cycle in humid environments above 60℃.
Use locknuts (M16) with 18-22N·m torque for rod-end connections.
