Description
SAIJ63 Adjustable Cylinder
1. ISO15552 (formerly ISO6431) standard compliant cylinder
2. Features asymmetric bidirectional sealing structure with compact dimensions and integrated oil reservoir function in piston sealing
3. H-shaped aluminum tubing with rodless design enhances corrosion resistance; External sensor mounting grooves enable quick installation
4. Smooth and stable cushion adjustment mechanism
5. Multiple cylinder specifications and mounting accessories available for versatile applications
6. High-temperature resistant sealing materials support operating temperature range of 0~150℃
Category: Standard Cylinders | Brand: AIRTAC | Series: SAIJ63
Installation Best Practice:
For vertical installations exceeding 45° angle, install an air pressure holding valve (APHV) to prevent unintended rod drop. Maintain 0.5mm minimum alignment tolerance between rod end and load connection.

The SAIJ63AX750-20 features dual-path stroke adjustment through mechanical stoppers, enabling precise end-position calibration without disassembly. Its hardened chromium piston rod (HRC 35-40) and aluminum alloy barrel ensure durability in high-cycle applications. The cylinder incorporates a wear-compensation design that maintains seal integrity beyond 5,000km cumulative travel distance.
Industrial Applications:
- Variable-height positioning in automated packaging lines
- Precision web tension control in printing machinery
- Adjustable clamping mechanisms for CNC fixture systems
- Material handling with variable stacking heights
- Plastic injection molding ejector systems
Installation Best Practice:
For vertical installations exceeding 45° angle, install an air pressure holding valve (APHV) to prevent unintended rod drop. Maintain 0.5mm minimum alignment tolerance between rod end and load connection.
Stroke Adjustment Procedure:
- Loosen the hexagonal lock nut (M8) on adjustment screw
- Rotate screw clockwise to decrease stroke (1 full rotation = 1.5mm adjustment)
- After alignment, apply 12-15N·m torque to lock nut while holding screw stationary
- Perform 3 full extension/retraction cycles to verify stability
