About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-10S
The AirTAC SAIJ100X115-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the nominal 115 mm stroke by up to 10 mm for a usable travel window of 105-115 mm. It delivers 3927 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod for improved corrosion resistance. The integrated -S magnet enables position feedback via CMSE reed and DMSE electronic sensors.
Because the adjuster acts purely as a mechanical stop on the retract end, it fine-tunes end positions at commissioning without requiring external stops or cylinder swaps. This extruded aluminum profile cylinder includes variable air cushions at both ends and uses a PT tapered G1/2 port. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-10S Is Used
Precision End-Stop Tuning
Dial in the exact 105-115 mm retract position during machine commissioning without swapping cylinders or adding external mechanical stops.
Product Size Changeover
Quickly adapt automated lines to new product lengths by adjusting the rear stopper within the 10 mm window to accommodate varying material dimensions.
Heavy Fixture Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy jigs and fixtures into place while relying on the PT tapered G1/2 port for robust airflow.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-10S the Right Cylinder?
Select this 100 mm bore when an 80 mm bore (2513 N at 0.5 MPa) is insufficient for moving heavy fixtures, but you want to avoid the larger 125 mm class. The 10 mm adjustment range is ideal for product changeovers where exact end-of-stroke positioning varies slightly. For any load-holding requirements without live air pressure, note that the rear adjuster and air cushion only decelerate the travel end; you must use a SAIL air-released lock, a BSAI clamp-lock, or an external rod lock. To match this ISO 15552 cylinder, specify the 100 mm bore, 115 mm stroke, 10 mm adjustment, PT G1/2 port, and the -S magnet.
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 SAIJ100 Adjustable Cylinder SAIJ100AX115-10S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you step up to 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective stroke from its nominal 115 mm down to 105 mm. This creates a 105-115 mm usable travel window for fine-tuning the retract end position at commissioning without changing the cylinder itself.
