High-precision ISO-compliant pneumatic cylinder featuring dual anti-rotation design and corrosion-resistant construction. The SI50BX145S incorporates wear-compensating seals and magnetic piston for position sensing compatibility. Optimized for repetitive heavy-load applications with its 4-stage buffer system that reduces end-impact noise by 30% compared to standard models.
- Automated assembly line clamping units
- Plastic injection molding ejectors
- CNC machine tool door actuators
- Material handling lift mechanisms
- Automotive welding fixture positioning
Installation note:
Maintain 0.1-0.3 mm alignment tolerance during mounting. Lubricate with ISO VG32 hydraulic oil
if used without built-in lubricator. For vertical mounting, install rod-down orientation to
prevent seal wear from piston self-weight.
