About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-50S
The AirTAC SAIJ80X750-50-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that allows you to fine-tune the travel window from 700 to 750 mm without swapping out hardware. Delivering 3518 N of push force at 0.7 MPa, it is built with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and a PT tapered port thread. The integrated -S magnet supports electronic DMSE and reed CMSE position sensing.
This adjustable-stroke design saves time during commissioning and product changeovers by dialing in the exact retract end-position externally. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 configurations. Remember that the rear adjuster acts only as a travel stop, not a load lock; it will not hold the payload without continuous live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-50S Is Used
Variable End-Stop Machining
Dial in the exact 700-750 mm retract position for machining operations or cutting stations that process multiple part lengths on the same fixture.
Product Changeover Diverter
Quickly reconfigure the stroke on packaging lines to handle different carton sizes, using the rear stopper to set new end positions without changing the cylinder.
Long-Stroke Assembly Press
Leverage the 3518 N push force at 0.7 MPa for long-travel assembly tasks, using the PT tapered ports and SUS420J2 rod for robust, leak-free operation.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX750-50S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires substantial thrust, such as 3518 N at 0.7 MPa, alongside a highly variable end-stop. If you need less force, stepping down to a 63 mm bore yields 2182 N at 0.7 MPa. Conversely, moving up to a 100 mm bore provides 5497 N at 0.7 MPa for heavier payloads. The adjustable 50 mm window makes this unit ideal for machines processing varying product sizes, replacing the need for a fixed-stroke SAI cylinder.
Because the stroke is 750 mm, the 25 mm rod needs external guidance to prevent excessive side-loading and premature seal wear. For applications requiring the load to stay in place without live air, consider an AirTAC SAIL or BSAI locking cylinder. To replace an ISO 15552 unit, match the 80 mm bore, 750 mm stroke, 50 mm adjustment, G3/8 PT ports, and -S magnet.

- ✓ Side load — consider a guided cylinder
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 SAIJ80 Adjustable Cylinder SAIJ80AX750-50S FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder generates 3518 N of push force and 2268 N of pull force. The maximum thrust is 4523 N at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 750 mm stroke by up to 50 mm, providing a usable travel window of 700 to 750 mm. The adjuster acts only as a mechanical stop and does not lock the load without live air pressure.
