About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-40S
The AirTAC SAIJ100X105-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down to a 65-105 mm window during commissioning. Featuring a 100 mm bore, it delivers a robust 7068 N push force at 0.9 MPa, making it ideal for heavy-duty positioning tasks.
This variant includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet enables precise end-of-stroke detection with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-40S Is Used
Variable End-Stop Forming
Dial in the exact 65-105 mm travel window on the fly to accommodate different material thicknesses in a forming press without swapping out the entire actuator.
Machine Changeover
Quickly reposition the rear stopper during product size changeovers on a packaging line, using the 100 mm bore's 5497 N force at 0.7 MPa to drive heavy tooling.
Heavy-Duty Assembly Press
Leverage the 7068 N push force at 0.9 MPa for robust pressing operations while relying on the PT G1/2 port and ISO 15552 footprint for straightforward integration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-40S the Right Cylinder?
Select this 100 mm bore actuator when an application requires substantial thrust—up to 7068 N at 0.9 MPa—alongside variable end-stop positioning. If your process needs less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa. The rear adjuster acts purely as a travel stop to decelerate the load; it does not hold the load without live air. For true pneumatic locking without pressure, consider the SAIL or BSAI clamp-lock series.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 105 mm nominal stroke, 40 mm adjustment range, PT G1/2 port, and the -S magnet requirement. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Since the 105 mm stroke is short, side-load risks are minimal, but always guide the load externally for rigid lateral stability.

- ✓ 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 SAIJ100AX105-40S FAQ
This 100 mm bore cylinder delivers a push force of 3927 N at 0.5 MPa, 5497 N at 0.7 MPa, and 7068 N at 0.9 MPa. The pull force is 3681 N at 0.5 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 105 mm stroke by up to 40 mm, providing a usable travel window of 65 to 105 mm. It only sets the end position and does not lock the load without live air pressure.
