About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-40S
The AirTAC SAIJ100X95-40-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 95 mm stroke that can be fine-tuned backward by up to 40 mm, creating a precise 55 to 95 mm usable travel window. Operating at 0.5 MPa, it delivers 3927 N of push force and 3681 N of pull force through a G1/2 port.
This variant includes a standard magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel integrates sensor grooves on both sides, and the carbon steel rod with an M20x1.5 thread handles robust side loads. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-40S Is Used
End-Position Tuning
Dial in the exact 55-95 mm travel distance during machine commissioning without swapping hardware.
Product Changeover
Quickly adapt end-stops on a packaging line to accommodate varying package sizes on the fly.
Variable Stroke Clamping
Apply up to 5497 N of clamping force at 0.7 MPa while fine-tuning the retraction point.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-40S the Right Cylinder?
Choose this 100 mm bore when an application requires substantial thrust—3927 N at 0.5 MPa or 5497 N at 0.7 MPa. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa, whereas a 125 mm bore provides 6136 N. The integrated -40 mm rear adjuster is ideal for variable end-stops or product changeovers, eliminating the need to physically swap cylinders or bolt on external stops during commissioning.
Because the 95 mm stroke is under the 300 mm threshold, side-load concerns are minimal, though the robust 25 mm rod and M20x1.5 thread provide excellent stability. Remember that the rear adjuster acts solely as a travel stop and does not hold the load without live air; for true load-holding without pressure, select an AirTAC SAIL or BSAI cylinder. For a drop-in ISO 15552 replacement, match the 100 mm bore, 95 mm stroke, PT port threads, -40 mm adjustment, and -S magnet.

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 SAIJ100X95-40S FAQ
At 0.5 MPa, 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 screw allows you to shorten the 95 mm nominal stroke by up to 40 mm, yielding a usable travel window of 55 to 95 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
