About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-30
The AirTAC SAIJ100X105-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a nominal 105 mm stroke that can be fine-tuned backward by up to 30 mm, creating a precise 75-105 mm usable travel window. This adjustment allows you to dial in the exact end position during commissioning without adding external stops. Delivering 7068N of push force at 0.9 MPa, it handles heavy loads with ease.
This SKU is configured with a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. It uses a PT tapered port thread and lacks a piston magnet, meaning it relies on external mechanical stops rather than internal position sensing. The extruded aluminum barrel includes sensor grooves on both sides should you later need a switch, while the variable air cushions at both ends absorb end-of-stroke kinetic energy.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-30 Is Used
Machine Changeover
Dial in the 75-105 mm travel window during product size changes without physically replacing the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to perfect part seating or clamping force using the rear adjustment screw.
Heavy Assembly Press
Leverage the 7068N push force at 0.9 MPa to drive heavy components into place while trimming the final approach distance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-30 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust—7068N at 0.9 MPa—stepping up from a 63 mm bore that offers 2805N, or stepping down from a 125 mm bore delivering 11045N. The adjustable stroke is ideal for machine setups requiring variable end stops or frequent product-size changeovers, saving the cost of swapping a fixed-stroke SAI cylinder. Remember that the rear adjuster acts purely as a travel stop; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 105 mm nominal stroke, 30 mm adjustment range, PT port thread, and basic mounting style. Although the 105 mm stroke is relatively short, the robust 25 mm rod and M20x1.5 rod thread handle high side loads well, though any long, unsupported travel still necessitates an external guide. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ100AX105-30 FAQ
At 0.9 MPa, this 100 mm bore cylinder provides 7068N of push force and 3681N of pull force. It can deliver a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 105 mm down to as little as 75 mm. This stop does not lock the load; live air pressure is required to hold position.
