About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-30S
The AirTAC SAIJ100X105-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 105 mm stroke that can be fine-tuned down by up to 30 mm, giving you a precise 75-105 mm usable travel window for product changeovers. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads with ease.
This variant includes a piston magnet for position sensing with CMSE reed or DMSE electronic switches. It uses a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel design integrates sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-30S Is Used
Machine Changeover
Dial in the 75-105 mm travel window during product size transitions to set new end stops without swapping cylinders.
End-Position Tuning
Fine-tune the retract end position at commissioning to absorb mechanical tolerances and ensure exact placement.
Heavy Load Positioning
Leverage the 3927 N push force to move heavy assemblies into place while using the adjuster to set the final resting point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-30S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (2513 N push at 0.5 MPa) is insufficient, but a 125 mm bore is overkill. The adjustable rear stopper is ideal for dialing in exact end positions during commissioning without adding external stops. For strokes of 300 mm or more, you would need an external guide to prevent side-load wear, but at 105 mm, the 25 mm rod handles standard loads well.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air. If your application requires position holding without pneumatic pressure, consider the SAIL lock or BSAI clamp-lock cylinders. To match this ISO 15552 interchangeable unit, specify the 100 mm bore, 105 mm stroke, 30 mm adjustment, PT G1/2 port, and the -S magnet option.

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 SAIJ100AX105-30S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.9 MPa, the push force reaches 7068 N. The operating speed range for this 100 mm bore is 30-800 mm/s.
The rear adjuster screw lets you shorten the effective travel by up to 30 mm, creating a 75-105 mm usable window. It acts as a physical stop to fine-tune the end position and does not lock the load without live air.
