About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-40
The AirTAC SAIJ100X160-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 160 mm travel by up to 40 mm. This creates a 120-160 mm usable window, enabling precise end-position tuning at commissioning without swapping out the physical actuator. It delivers substantial thrust, pushing with 5497 N and pulling with 3681 N at 0.7 MPa.
This unit features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Remember that the rear adjuster acts purely as a travel stop for deceleration alongside the air cushions; it does not lock the load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-40 Is Used
Changeover Calibration
Dial in the 120-160 mm stroke window during machine setup to accommodate new product sizes without physically replacing the actuator.
Heavy Clamping
Leverage the 5497 N push force at 0.7 MPa to secure heavy workpieces, using the rear stopper to set the exact clamping depth.
Variable Diverting
Adjust the retract end-position on the fly to handle different package lengths on a sorting line, ensuring precise physical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX160-40 the Right Cylinder?
Selecting this 100 mm bore actuator makes sense when your application demands high thrust—such as 5497 N at 0.7 MPa—combined with variable end-stop positioning. If you need less force and a smaller footprint, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa. Conversely, moving up to a 125 mm bore provides 8590 N at 0.7 MPa for heavier payloads. The adjustable-stroke design is specifically chosen over a fixed SAI cylinder when you need fine-tuning during product changeovers rather than relying on external stops.
Because the nominal stroke is 160 mm, external guiding is recommended to manage side loads. To achieve a true ISO 15552 replacement match, verify the 100 mm bore, 160 mm stroke, 40 mm adjustment, PT G1/2 port, and your required mounting style from the available set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that FB, CA, CB, and CR mounts are omitted from this series. If your setup requires holding a load without live air, consider the SAIL or BSAI locking variants instead.

- ✓ 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 SAIJ100AX160-40 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 160 mm down to 120 mm. This provides a 120-160 mm usable window for fine-tuning the retract end-position at commissioning.
At 0.7 MPa operating pressure, the SAIJ100X160-40 provides a push force of 5497 N and a pull force of 3681 N. It can reach a maximum push force of 7068 N at 0.9 MPa.
