About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-40
The AirTAC SAIJ160X90-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 14074N of push force at 0.7 MPa. It features a 90 mm nominal stroke that can be fine-tuned down by up to 40 mm, providing a usable travel window between 50 and 90 mm. This adjustability allows you to dial in the exact retract end-position during commissioning without swapping out the cylinder or adding external stops.
Built with a SUS420J2 stainless steel rod (material code A) and PT tapered ports, this large-bore unit is designed for heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. While the rear screw sets the travel limit and the variable air cushions decelerate the piston, neither component will hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-40 Is Used
Heavy Press Fitments
Dial in the exact 50-90 mm insertion depth for large bearings or heavy press fits during machine setup, ensuring precise alignment without mechanical retooling.
Product Size Changeovers
Adapt quickly to varying product lengths on a production line by adjusting the retract stop up to 40 mm, minimizing downtime between production runs.
End-Stop Calibration
Fine-tune the final resting position of heavy actuators at commissioning, using the rear stopper to compensate for mechanical tolerances in the fixture.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-40 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires substantial thrust—such as the 10053N pull force at 0.5 MPa—but also demands on-the-fly end-position tuning to accommodate product changeovers. If your process needs less force, stepping down to a 125 mm bore yields 6136N of push at 0.5 MPa, whereas moving up to a 200 mm bore provides 15708N. The integrated 40 mm adjustment window here replaces the need to inventory multiple fixed-stroke SAI cylinders for slightly varying job lengths.
When matching an ISO 15552 replacement, confirm the 160 mm bore, 90 mm stroke, 40 mm adjustment range, PT port threads, and your desired mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Because this cylinder lacks the -S magnet suffix, it will not work with AirTAC CMSE or DMSE sensors without modification.

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 SAIJ160 Adjustable Cylinder SAIJ160AX90-40 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074N of push force and 13274N of pull force. At the maximum 1.0 MPa pressure, it achieves a top push force of 18095N.
The rear adjuster acts as a mechanical stop that shortens the 90 mm nominal stroke by up to 40 mm, creating a usable travel window of 50 to 90 mm. It sets the end position and works with the air cushions for deceleration, but it does not lock the load without continuous air pressure.
