The SI50BX140 industrial cylinder features high rigidity piston structure with precision honed tube for smooth operation. Its integrated cushioning mechanism reduces impact noise by 40% compared to basic models. The corrosion-resistant design includes triple-layered rod sealing (wiper + main seal + rod guide) for harsh environments. Requires ISO 8573-1:2010 Class 3 compressed air.
- Automated assembly line clamping mechanisms
- Plastic injection molding machine ejectors
- CNC machine tool fixture actuation
- Automotive welding jig positioning
- Packaging machine pusher systems
Installation recommendation:
For vertical mounting applications exceeding 30° inclination, install rod-end locking nut (accessory code LN-50)
to prevent piston drift. Maintain 0.5–1mm alignment tolerance during mounting.
