About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-30S
The AirTAC SAIJ63X105-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 105 mm nominal stroke by up to 30 mm. This creates a precise 75-105 mm usable travel window for fine-tuning end positions during commissioning without swapping hardware. It delivers 1559 N of push force and 1402 N of pull force at 0.5 MPa.
This variant features an SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. You can mount CMSE reed or DMSE electronic switches directly into the sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop to set deceleration, so it will not hold a load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-30S Is Used
Machine Changeover
Quickly adjust the 75-105 mm travel window during product size changes without replacing the cylinder or adding external stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to dial in exact mechanical stops for critical assembly processes.
Variable End Stops
Use the 30 mm rear adjuster to alter the stroke limit on packaging equipment for different material thicknesses.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX105-30S the Right Cylinder?
Choose this 63 mm bore when an application requires around 1559 N push force at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N, or down from an 80 mm bore yielding 2513 N. The adjustable stroke is ideal for product changeovers on a line, letting you shift the end-stop by up to 30 mm on the fly instead of installing a fixed SAI cylinder. For load-holding without continuous air pressure, you must integrate an external pilot-operated check valve or look at the SAIL or BSAI series, as the SAIJ adjuster is not a lock.
To match this ISO 15552 interchangeable cylinder exactly, specify a 63 mm bore, 105 mm stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet option. The G3/8 port and M16x1.5 rod thread handle robust pneumatic flow, while the 20 mm rod diameter provides excellent resistance to side loading. Operating speed ranges from 30-800 mm/s.

- ✓ 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 SAIJ63AX105-30S FAQ
The rear adjuster screw lets you shorten the 105 mm nominal stroke by up to 30 mm, providing a usable travel window of 75-105 mm. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa, the SAIJ63X105-30-S provides 1559 N of push force and 1402 N of pull force. It can reach up to 2805 N push force at its maximum 0.9 MPa operating pressure.
