About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-75
The AirTAC SAIJ100X170-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 7068N of push force at 0.9 MPa, paired with a usable travel window of 95-170mm. This 75mm adjustment range allows you to dial in the exact end-of-stroke position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This specific configuration features a SUS304 stainless steel rod (code B) for superior corrosion resistance in humid or washdown environments. It uses a PT tapered port thread and a robust M20x1.5 rod thread. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not lock or hold the load without live air pressure. For position holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-75 Is Used
Multi-Product Changeover
Quickly adapt end-stops on a packaging line when switching between box sizes, using the 95-170mm travel window to set precise pushing distances without changing hardware.
Commissioning Fine-Tuning
Dial in the exact retract position during machine setup to clear mechanical interference or perfect a pressing force, leveraging the 75mm rear adjustment screw.
Corrosive Heavy Loads
Utilize the 7068N push force and SUS304 stainless steel rod to move heavy pallets or components in environments requiring frequent washdowns.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX170-75 the Right Cylinder?
Choose this 100mm bore when your application requires heavy thrust—delivering 3927N push at 0.5 MPa—necessitating a step up from the 80mm bore which provides 2513N at the same pressure. The 75mm adjustment window is ideal for machines running multiple product sizes, letting operators fine-tune the retract position on the fly rather than swapping out a fixed-stroke SAI cylinder. When ordering, confirm the 100mm bore, 170mm stroke, 75mm adjustment, PT port, and SUS304 rod material.
Because the nominal stroke is 170mm, side-load risks are moderate, but always ensure proper guiding for heavy loads. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found in some other lines.

- ✓ 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 SAIJ100BX170-75 FAQ
At 0.5 MPa it provides 3927N of push and 3681N of pull. At the maximum operating pressure of 1.0 MPa, it achieves a maximum push force of 801 kgf.
The rear adjuster screw lets you mechanically shorten the effective travel from 170mm down to 95mm. It functions as a travel stop to set the end position, but it does not lock the load without continuous air pressure.
