About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-20S
The AirTAC SAIJ160X600-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 600 mm stroke by up to 20 mm. This yields a highly precise 580-600 mm usable travel window, enabling exact end-position tuning at commissioning without swapping out the entire unit or adding external mechanical stops. It delivers substantial thrust, generating 14074N of push force and 9425N of pull force at 0.7 MPa.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance and pairs seamlessly with AirTAC CMSE reed and DMSE electronic sensors via its integrated side-mounted magnet grooves. Fluid supply is routed through PT tapered G3/4 ports, while the extruded aluminum barrel design incorporates variable air cushions at both ends to manage the kinetic energy of this large-bore actuator.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 580-600mm retract position during heavy-duty press setups to accommodate varying material thicknesses without re-engineering the fixture.
Automated Line Changeover
Adjust the rear stopper quickly during product size changeovers on a packaging line, saving downtime by avoiding complete cylinder replacement.
Large Fixture Positioning
Move substantial jigs using the 14074N thrust at 0.7MPa, relying on the SUS420J2 rod to resist corrosion in humid plant environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-20S the Right Cylinder?
Selecting this 160 mm bore is appropriate when an application demands nearly 14100N of thrust at 0.7 MPa, bridging the gap between the 6136N output of the 125 mm bore and the massive 15708N push force of the 200 mm variant. The adjustable stroke is chosen over a fixed SAI model when product changeovers require variable end-stops or when fine-tuning the retract position during machine setup. Because the nominal stroke is 600 mm, an external guide is strongly recommended to prevent excessive side-loading on the 40 mm rod and its M36x2 thread.
For an exact ISO 15552 replacement, match the 160 mm bore, 600 mm nominal stroke, 20 mm adjustment range, PT G3/4 port, and the -S magnet requirement. Note that the rear adjuster acts purely as a travel stop and the air cushions provide deceleration; neither will hold a load without continuous live air pressure. For true load-holding, integrate an external pilot-operated check valve or explore the SAIL or BSAI series instead. The available SAIJ 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 SAIJ160AX600-20S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074N of push force and 9425N of pull force. It can achieve a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 600 mm down to 580 mm, providing a 580-600 mm usable window. This stopper fine-tunes the end position but does not lock the load without live air pressure.
