About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-40S
The AirTAC SAIJ100X95-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 55-95 mm usable travel window. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads while allowing precise end-position tuning during commissioning. The barrel is extruded aluminum with sensor grooves on both sides.
This specific SKU includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a PT tapered port thread. Equipped with a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear screw acts as a travel stop for deceleration, not a lock, meaning live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-40S Is Used
Variable End Stops
Dial in the exact clamping depth between 55 and 95 mm on machining fixtures without swapping cylinders or adding physical shims.
Product-Size Changeovers
Quickly reconfigure diverter arms on a packaging line to handle different carton lengths by adjusting the rear stopper.
Heavy Press Setup
Fine-tune the 3927 N pressing force travel end during machine commissioning to prevent crushing delicate components.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-40S the Right Cylinder?
Choose this 100 mm bore when the 80 mm class is insufficient, as the SAIJ80 provides 2513 N push at 0.5 MPa, but the 100 mm bore yields 3927 N. The 40 mm adjustment range is ideal for product-size changeovers on a line, letting you dial back the 95 mm nominal stroke without adding external stops. For load-holding without air pressure, select a SAIL or BSAI cylinder instead of relying on the adjuster.
To replace an ISO 15552 cylinder, match the 100 mm bore, 95 mm stroke, PT port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since this cylinder uses a 25 mm rod with an M20x1.5 thread, it carries high side loads, but any stroke over 300 mm would still require an external guide.
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 SAIJ100BX95-40S FAQ
At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.7 MPa the push force increases to 5497 N.
The rear adjuster screw trims the nominal 95 mm stroke back by up to 40 mm, giving a usable travel window of 55-95 mm. It functions as a travel stop and does not lock the load without live air.
