About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-40S
The AirTAC SAIJ160X600-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 560-600 mm window. It delivers immense thrust, pushing 14074 N at 0.7 MPa and pulling 9425 N, making it suitable for heavy-duty industrial positioning. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for use with CMSE reed and DMSE electronic solid-state switches.
This model uses a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads (G3/4). The rear adjustment screw acts purely as a mechanical stop to set the retract end position; it does not hold the load without live air pressure. For applications requiring true load-holding without continuous air, an external rod lock or related series like SAIL or BSAI should be used.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-40S Is Used
Machine Changeover
Dial in the 560-600 mm travel window during product size changes without physically replacing the cylinder or re-engineering fixed external stops.
Heavy Press Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy assemblies, using the rear screw to fine-tune the final clamping position.
Long-Stroke Guiding
Execute 600 mm movements while relying on the external guide system to manage side loads, with the adjuster setting the precise retract limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX600-40S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore's 5497 N push force at 0.7 MPa is insufficient, but you want to avoid stepping up to the massive 200 mm frame. The 40 mm adjustment range is highly valuable during machine commissioning or product changeovers, allowing you to dial in the exact end-stop without swapping cylinders or adding external stops. Because the 600 mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the 40 mm diameter rod.
When matching this for an ISO 15552 replacement, verify the 600 mm stroke, 40 mm adjustment, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR mounts found in some other series.

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 SAIJ160AX600-40S FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf of push force.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 600 mm nominal stroke by up to 40 mm, creating a usable 560-600 mm travel window. It sets the end position but does not lock the load without live air pressure.
