About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-40S
The AirTAC SAIJ80X95-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 55 to 95 mm window. Delivering 2513 N of pull force at 0.5 MPa, it is built with an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with CMSE reed and DMSE electronic solid-state sensors.
Unlike a fixed-stroke SAI cylinder, this model lets you dial in the exact retract end-position during commissioning or product changeovers without adding external stops. The rear adjuster acts purely as a travel stop to set the deceleration point alongside the standard air cushions; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-40S Is Used
Machine Changeover
Quickly adjust the retract end-stop within the 55-95 mm window when switching between product sizes on a packaging line, avoiding mechanical rebuilds.
End-Position Tuning
Fine-tune the final resting position of a tooling head during commissioning to achieve exact alignment without swapping out the entire actuator.
Variable End Stops
Dial in the precise stroke distance for assembly presses that need to accommodate multiple part heights on the fly using the rear adjuster.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-40S the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust—such as 2513 N pull at 0.5 MPa—but demands a highly specific retract distance within the 55-95 mm range. If your force requirements are lower, stepping down to a 63 mm bore yields 1402 N of pull force, whereas stepping up to a 100 mm bore provides 3681 N. The PT tapered port threads ensure a robust pneumatic seal, and the integrated magnet allows for precise end-of-stroke detection using CMSE or DMSE switches.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 95 mm nominal stroke, 40 mm adjustment range, PT port thread, and -S magnet option. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the 25 mm rod and M20x1.5 thread handle side loads well, always support any lengthy or heavy loads with an external guide to prevent premature seal wear.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ 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 SAIJ80AX95-40S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 40 mm, providing a usable travel window of 55 to 95 mm. It sets the travel end and works with the air cushions for deceleration, but it is not a lock and will not hold the load without continuous air pressure.
Operating at 0.5 MPa, the SAIJ80X95-40-S generates 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
