About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-100S
The AirTAC SAIJ63X190-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 1559 N of pull force at 0.5 MPa and features a 90-190 mm usable travel window, allowing you to trim the 190 mm nominal stroke by up to 100 mm during commissioning. The SUS420J2 stainless steel rod (code A) provides excellent corrosion resistance, and the integrated magnet supports CMSE reed and DMSE electronic sensors.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops when fine-tuning end positions. It uses a PT tapered port thread (G3/8) and includes variable air cushions at both ends. The rear adjuster functions strictly as a travel stop for deceleration, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-100S Is Used
Product Changeovers
Dial in the 90-190 mm travel window on the fly to accommodate varying package sizes without changing the cylinder.
Machine Commissioning
Fine-tune the retract end-position precisely during setup to avoid costly mechanical hard-stops.
Variable End Stops
Use the 100 mm rear adjustment screw to set multiple retract distances for flexible assembly tooling.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX190-100S the Right Cylinder?
Choose this 63 mm bore cylinder when you need 1559 N pull force at 0.5 MPa with highly flexible end-position tuning. If your application requires less force, the 50 mm bore offers 825 N pull; if you need more, step up to the 80 mm bore providing 2268 N. The 100 mm adjustment range is ideal for machines handling frequent product-size changeovers. For an exact ISO 15552 replacement match, verify the 190 mm stroke, 100 mm adjustment, PT port, and -S magnet. Since the stroke is under 300 mm, side-load risks are moderate, but external guides are still recommended for heavy loads.
If your setup demands load-holding without continuous air pressure, a standard SAIJ is insufficient because the rear screw is only a stop. In those cases, consider the SAIL air-released lock or BSAI clamp-lock cylinder instead.
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 SAIJ63AX190-100S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 190 mm nominal stroke by up to 100 mm, providing a usable travel window of 90-190 mm. It only sets the travel end and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of pull force and 2182 N of push force at 0.7 MPa. The maximum push force is 2805 N at 0.9 MPa.
