About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-20S
The AirTAC SAIJ100X95-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. With a 95 mm nominal stroke and a 20 mm adjustment range, it provides a usable travel window of 75-95 mm without requiring external stops. It delivers robust thrust, pushing 3927 N and pulling 3681 N at 0.5 MPa.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for position sensing. It operates at speeds of 30-800 mm/s and uses a G1/2 port. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-20S Is Used
Product Changeovers
Quickly adapt to varying package sizes on a packaging line by dialing the rear adjuster to shift the 75-95 mm travel window without changing hardware.
Machine Setup
Fine-tune the end-of-stroke position during initial commissioning to perfectly seat components, utilizing the 3927 N push force at 0.5 MPa.
Corrosive Environments
Leverage the SUS304 stainless steel rod for pressing or lifting tasks in food processing or chemical areas where standard carbon steel rods would fail.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-20S the Right Cylinder?
Choose this 100 mm bore when 50 mm cylinders (providing 982 N push at 0.5 MPa) lack the necessary force, but you want to avoid stepping up to the heavier 125 mm bore. The adjustable 75-95 mm travel window is ideal for product changeovers on a line, letting you dial in the exact end-stop mechanically rather than swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 95 mm stroke, 20 mm adjustment, PT port thread, and -S magnet. This SAIJ model supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR options. The -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.

- ✓ 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 SAIJ100BX95-20S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you trim the effective stroke within a 75-95 mm travel window. It acts as a mechanical stop to set the retract end position and does not lock the load without continuous air pressure.
