About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-10S
The AirTAC SAIJ63X130-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down to a 120-130 mm window without adding external stops. Delivering 1559 N of push force and 1402 N of pull force at 0.5 MPa, it fits mid-range automation tasks perfectly. This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a standard magnet for position sensing.
Sensing is handled by standard AirTAC CMSE reed or DMSE electronic switches mounted into the extruded aluminum barrel's dual sensor grooves. The rear adjuster acts purely as a mechanical stop to dial in the exact end position during commissioning; it does not lock the load without live air pressure. Fluid supply is routed through PT tapered G3/8 ports, and the cylinder achieves speeds of 30-800 mm/s with adjustable air cushions at both ends.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-10S Is Used
Machine Changeover
Dial in the 120-130 mm travel window during product size transitions to perfectly set the new end position without changing the cylinder.
Assembly Positioning
Use the 1559 N push force to press components, relying on the rear stopper to absorb mechanical variances and guarantee precise final placement.
Sensor Calibration
Leverage the standard magnet and dual sensor grooves to mount CMSE or DMSE switches exactly where the adjusted stroke ends.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-10S the Right Cylinder?
Choose this 63 mm bore when an application requires around 1559 N of thrust at 0.5 MPa but demands on-site end-position tuning, stepping up from a 50 mm bore that provides 982 N. The 10 mm adjustment range is ideal for absorbing minor mechanical tolerances during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. For load-holding requirements without continuous air pressure, this adjuster will not suffice; consider an SAIL or BSAI series cylinder instead.
When replacing an ISO 15552 cylinder, match the 63 mm bore, 130 mm nominal stroke, 10 mm adjustment range, PT G3/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR. Because the 130 mm stroke is relatively short, the 20 mm rod handles side loads well, though external guides remain recommended for any off-center loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX130-10S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
The rear adjuster screw allows you to shorten the 130 mm nominal stroke by up to 10 mm, creating a 120-130 mm usable travel window. It functions as a mechanical stop for fine-tuning end positions and does not hold the load without live air pressure.
