About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-40S
The AirTAC SAIJ160X700-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the retract travel by up to 40 mm. This yields a precise 660-700 mm usable travel window, enabling fine end-position tuning at commissioning without swapping the barrel or adding external stops. As a large-bore 160 mm unit, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for position sensing. The extruded aluminum barrel provides sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic switches. 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.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-40S Is Used
Heavy Press Tuning
Fine-tune the 660-700 mm retract end-stop during heavy press commissioning to dial in the exact clamping distance without machining custom spacers.
Product Changeover
Adjust the rear stopper up to 40 mm on a packaging line to accommodate different large-format product sizes quickly and accurately.
Long-Stroke Forming
Leverage the 14074 N push force at 0.7 MPa for deep-draw forming tasks, using the rear adjuster to limit forward travel for variable material thicknesses.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-40S the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires heavy thrust—10053 N push at 0.5 MPa or 14074 N at 0.7 MPa—and variable end-stop positioning. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N at 0.7 MPa. The adjustable-stroke design is favored over a fixed-stroke SAI cylinder during machine setup or product-size changeovers, letting you fine-tune the retract position on the fly.
For this SAIJ160X700-40-S configuration, ensure you specify the PT tapered port thread, the SUS420J2 rod material, and the -S magnet option. Because the nominal stroke is 700 mm, the long unsupported rod is susceptible to side-loading; an external guide rail is recommended to prevent premature seal wear. Note that the rear adjuster and air cushions only decelerate the travel end; for true load-holding without live air, select an SAIL (air-released lock) or BSAI (clamp-lock) cylinder. SAIJ supports a reduced mounting set: 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 SAIJ160AX700-40S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At 0.5 MPa, it delivers 10053 N push and 9425 N pull.
The external rear screw stopper allows you to shorten the effective retract stroke by up to 40 mm from its 700 mm nominal length, creating a 660-700 mm adjustable travel window. It acts as a mechanical stop and does not hold the load without continuous air pressure.
