About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-75S
The AirTAC SAIJ100X170-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 170 mm travel by up to 75 mm. This creates a highly flexible 95-170 mm usable window, letting you fine-tune the retract end position during commissioning without swapping hardware. It delivers robust thrust, providing 3927 N push force at 0.5 MPa and up to 7068 N at 0.9 MPa.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, while the available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts purely as a travel stop and does not lock the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-75S Is Used
Machine Changeover
Dial in the 95-170 mm travel window rapidly during product size transitions without changing the cylinder or adding external stopper blocks.
Heavy Clamping
Leverage the 7068 N push force at 0.9 MPa to secure heavy workpieces, using the rear screw to set the exact clamping depth.
Sensor Integration
Utilize the built-in magnet with DMSE electronic or CMSE reed switches in the dual sensor grooves to confirm the adjusted end position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX170-75S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial force, such as 3927 N push at 0.5 MPa. If you need less force, stepping down to an 80 mm bore yields 2513 N push force, whereas moving up to a 125 mm bore provides 6136 N. The 75 mm adjustment range is exceptionally useful for prototyping or product-size changeovers, eliminating the need to bolt on external stops. For holding loads without continuous air pressure, this cylinder is insufficient; consider an AirTAC SAIL or BSAI locking cylinder instead.
Because the 170 mm stroke is relatively short for this large bore, side-loading is less problematic than with longer strokes, but you should still ensure the M20x1.5 rod thread is properly aligned. When replacing an existing ISO 15552 cylinder, verify the 100 mm bore, 170 mm stroke, PT tapered port threads, and the required mounting accessory. The operating speed ranges from 30-800 mm/s, supported by variable air cushions at both ends.
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 SAIJ100AX170-75S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm. This transforms the nominal 170 mm stroke into a 95-170 mm usable travel window, enabling precise end-position tuning at commissioning.
At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
