High-precision industrial cylinder featuring wear-resistant chromium-plated rod and optimized air cushion design. The SI40AX450S delivers smooth linear motion with position repeatability ±0.5mm, making it ideal for medium-load precision applications. Requires ISO 8573-1:2010 Class 3 lubricated or non-lubricated air.
- Automated assembly line positioning systems
- Die-casting machine ejection mechanisms
- CNC tool changers
- Paper processing equipment
- Automotive welding fixture clamping
Installation tip:
Allow minimum 2mm thermal expansion clearance when ambient temperature exceeds 50℃.
For vertical mounting, use locknut (AN4-LK) to prevent rod rotation. Lubricate through
air supply (ISO VG32 or equivalent) if non-lube version not used.
