About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-40S
The AirTAC SAIJ100X135-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 95 to 135 mm. Delivering 3927 N of push force at 0.5 MPa, it features a G1/2 port and a robust 25 mm piston rod. The integrated -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic solid-state switches.
This variant utilizes a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance. The external rear stopper allows precise end-position tuning during commissioning without swapping hardware, while the extruded aluminum barrel incorporates dual sensor grooves for flexible switch mounting.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-40S Is Used
Machine Setup Changeover
Fine-tune the 95-135 mm end position mechanically during product size changes, eliminating the need to physically swap out cylinders for varying part lengths.
Variable End-Stop Positioning
Dial in the exact retract distance on automated assembly tooling, using the rear screw to set precise stopping points without adding external shock absorbers.
High-Force Clamping
Leverage the 3927 N push force at 0.5 MPa to secure heavy workpieces, relying on the SUS420J2 stainless rod to resist corrosion in humid shop environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX135-40S the Right Cylinder?
Select this 100 mm bore when an application requires substantial thrust, stepping up from a 63 mm bore that provides 1559 N at 0.5 MPa. The 40 mm adjustment range is ideal for product changeovers on a packaging line, allowing you to dial in the exact end-stop mechanically rather than reprogramming fixed SAI cylinders. To replace an existing ISO 15552 unit, match the 100 mm bore, 135 mm stroke, PT tapered port thread, and the -S magnet requirement.
Because the stroke is 135 mm, side-load stress is moderate, but the 25 mm rod and M20x1.5 thread handle standard guiding duties well. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX135-40S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from the nominal 135 mm down to 95 mm. It sets the travel end but does not lock the load without continuous air pressure.
