Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-75
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 90mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-75
The AirTAC SAIJ160X90-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 90 mm stroke by up to 75 mm. This yields a highly flexible 15-90 mm usable travel window, enabling precise end-position tuning at commissioning without swapping out the physical cylinder. Built to deliver immense thrust, it generates 14074 N of push force at 0.7 MPa and up to 18095 N at 0.9 MPa.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and carries PT tapered port threads sized at G3/4. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a travel stop to set the retraction end, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-75 Is Used
Heavy Press Tuning
Dial in the exact 15-90 mm travel window during heavy press commissioning to accommodate varying material thicknesses without adding external mechanical stops.
Product Changeovers
Rapidly adjust the retraction end-position on automated assembly lines when switching between different product sizes or tooling heights.
Variable End Stops
Use the 75 mm adjustment range to create variable end-stops for testing equipment that requires different stroke lengths across multiple test cycles.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX90-75 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires massive force—such as the 10053 N push output at 0.5 MPa—and highly variable end-stops. If you do not need this level of thrust, stepping down to a 125 mm bore provides 6136 N at 0.5 MPa, saving space and air consumption. Conversely, if you need even greater power, the 200 mm bore offers 15708 N at 0.5 MPa. The adjustable stroke is ideal for product-size changeovers on a line, whereas a fixed-stroke SAI cylinder is better for dedicated, single-purpose tasks.
Because the nominal stroke is 90 mm, the unsupported rod length is relatively short, minimizing side-load concerns compared to longer strokes. However, the rear adjuster is a stop, not a lock; for load-holding without live pressure, consider an AirTAC SAIL or BSAI cylinder. To match this exact unit for an ISO 15552 replacement, specify the 160 mm bore, 90 mm stroke, 75 mm adjustment, PT G3/4 port, and no magnet. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160AX90-75 FAQ
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw allows you to trim the effective travel from the 90 mm nominal stroke down to as little as 15 mm, creating a 15-90 mm usable window. This stopper sets the end position but does not lock the load without continuous air pressure.
