About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-40
The AirTAC SAIJ160X125-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7 MPa. Its built-in 40mm adjustment screw allows you to trim the effective travel down from the 125mm nominal stroke, creating an 85-125mm usable positioning window. This eliminates the need to swap cylinders during product changeovers.
The extruded aluminum barrel features sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later. This heavy-duty 160mm bore utilizes a robust 40mm carbon steel rod with an M36x2 thread, paired with 50mm variable air cushions at both ends to manage high kinetic energy. It operates at speeds of 30-500 mm/s and uses PT tapered ports sized at G3/4.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-40 Is Used
Heavy Press Tuning
Dial in the exact 85-125mm pressing depth during commissioning to prevent material damage, using the rear screw rather than swapping physical stopper blocks.
Product Changeover
Quickly adjust the end-of-stroke position on a packaging line when transitioning to different pallet sizes, leveraging the 40mm trim window without changing the cylinder.
Large Fixture Clamping
Secure heavy components with up to 14074N of push force at 0.7 MPa, fine-tuning the clamp reach to accommodate varied part tolerances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-40 the Right Cylinder?
Choose this 160mm bore when an application requires substantial thrust, such as 14074N push or 9425N pull at 0.7 MPa. If your setup demands less force, stepping down to a 125mm bore yields 8590N push force at the same pressure, whereas moving up to a 200mm bore provides 21991N. The adjustable stroke is ideal for fine-tuning end positions at commissioning without adding external stops.
For an exact ISO 15552 replacement match, verify the 125mm stroke, 40mm adjustment range, G3/4 PT ports, and your preferred mounting style. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Because the nominal stroke is 125mm, an external guide is recommended to manage side loads. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For fail-safe load holding, consider an external rod lock or the AirTAC SAIL 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 SAIJ160X125-40 FAQ
It features a rear mechanical stopper that allows you to shorten the 125mm nominal stroke by up to 40mm. This provides an adjustable travel window of 85-125mm, enabling precise end-position tuning without external stops.
At 0.7 MPa operating pressure, it provides 14074N of push force and 9425N of pull force. At a maximum 1.0 MPa, the push force reaches 18095N.
