About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-75S
The AirTAC SAIJ160X155-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 80 to 155 mm. Built with a robust 40 mm carbon steel rod and an M36x2 thread, it delivers 14074 N of push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The -S designation indicates an integrated magnet for position sensing.
This extruded aluminum profile cylinder features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear stopper allows precise end-position tuning during commissioning without adding external stops. Note that this adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-75S Is Used
Heavy Press Tuning
Dial in the exact 80 to 155 mm pressing depth during machine commissioning without swapping out the entire cylinder or adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper to accommodate varying product sizes on a heavy-duty assembly line, reducing downtime between production runs.
Variable End Stops
Provide a customizable retraction point for large material handling equipment, utilizing the 10053 N pull force at 0.5 MPa to reset heavy tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X155-75S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial thrust, such as 14074 N at 0.7 MPa, alongside variable end-stop positioning. If the 80 to 155 mm adjustable window is excessive, stepping down to a 125 mm bore yields 8590 N of push force at 0.7 MPa. Conversely, moving up to a 200 mm bore increases push force to 21991 N at 0.7 MPa. The PT tapered port and M36x2 rod thread are fixed to this bore size.
For an exact ISO 15552 replacement match, ensure the 160 mm bore, 155 mm stroke, 75 mm adjustment, PT port thread, and -S magnet option are specified. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 155 mm stroke falls below the 300 mm threshold, external side-load guides are less critical, though the heavy 40 mm rod inherently handles significant side loads. For load-holding without live air, consider an AirTAC SAIL or BSAI cylinder instead.

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 SAIJ160X155-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At the maximum 1.0 MPa pressure, it achieves a push force of 18095 N.
The rear adjuster acts as a mechanical stop that allows you to trim the effective stroke back by up to 75 mm from the nominal 155 mm, creating an 80 to 155 mm usable travel window. It sets the end position but does not lock the load without continuous air pressure.
