About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-100S
The AirTAC SAIJ100X150-100-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear mechanical adjuster that trims the retract stroke by up to 100 mm. This yields a highly flexible usable travel window of 50 to 150 mm, allowing precise end-position tuning at commissioning without swapping out the entire actuator. Equipped with a SUS420J2 stainless steel rod (material code A) and a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors.
Delivering 5497 N of push force at 0.7 MPa, this 100 mm bore actuator handles demanding workloads. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends decelerate the load. Remember that the rear screw acts strictly as a travel stop, not a lock; the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-100S Is Used
Variable End-Stop Tuning
Dial in the exact clamping depth between 50 and 150 mm during machine commissioning to accommodate varying material thicknesses without adding external hard stops.
Product Size Changeover
Rapidly reconfigure the retract position on a packaging line by adjusting the rear screw up to 100 mm, minimizing downtime when switching between different package dimensions.
High-Force Positioning
Leverage the 5497 N push force at 0.7 MPa to move and position heavy fixtures, using the fine stroke adjustment to guarantee precise mechanical endpoints.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-100S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (providing 3518 N push at 0.7 MPa) is insufficient for your tooling weight, or step down if the 3927 N at 0.5 MPa is excessive. The massive 100 mm adjustment range is ideal for machines processing multiple product sizes, enabling rapid changeover by dialing in the exact 50-150 mm travel limit rather than installing external stops. Because the 150 mm nominal stroke is relatively short, side-loading is less of a concern, but always guide the load rigidly.
To replace an ISO 15552 cylinder, match the 100 mm bore, 150 mm stroke, -100 adjustment, PT tapered port thread, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your application requires true load-holding without continuous air pressure, select an AirTAC SAIL or BSAI cylinder instead of relying on the SAIJ adjuster.

- ✓ 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 SAIJ100AX150-100S FAQ
The rear adjuster acts as a mechanical stop that shortens the nominal 150 mm stroke by up to 100 mm. This provides an adjustable usable travel window of 50 to 150 mm, allowing you to fine-tune the end position without changing the cylinder.
At an operating pressure of 0.7 MPa, the SAIJ100X150-100-S generates a push force of 5497 N and a pull force of 3681 N. It can deliver a maximum push force of 7068 N at 0.9 MPa.
