Precision-engineered adjustable stroke cylinder featuring dual-position cushioning control and anti-rotation rod design. The SAIJ63 series incorporates a unique stroke adjustment mechanism with ±2mm repeatability, achieved through an external locking screw and graduated scale. Enhanced durability comes from triple-lip rod seals and chrome-carburized piston rod surface treatment (Ra0.2μm). Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Variable height positioning in automated packaging lines
- Pressure-sensitive material handling systems
- Automotive assembly fixture clamping
- Die-casting machine ejection mechanisms
- Adjustable press tooling systems
Installation tip:
Always align cylinder axis within 0.2mm parallel tolerance during mounting.
For stroke adjustment: Loosen lock nut, rotate adjustment bolt (1 full turn = 5mm stroke change),
then re-tighten to 7-9N·m torque. Perform weekly lubrication via rod-end grease nipple.
