About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-10S
The AirTAC SAIJ80X75-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 2513N push force at 0.5 MPa and features a 65-75 mm usable travel window, allowing you to dial back the 75 mm nominal stroke by up to 10 mm during commissioning. This eliminates the need to swap cylinders or add external stops when fine-tuning end positions.
Built with a SUS420J2 stainless steel rod (option A) for corrosion resistance, it includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the standard PT G3/8 ports match the 80 mm bore class. It supports a 30-800 mm/s speed range and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-10S Is Used
Machine Changeovers
Fine-tune the 65-75 mm retract position on the fly when switching between product sizes, avoiding physical hardware swaps.
End-Stop Calibration
Dial in the exact end-of-stroke position during initial setup without adding bulky external stopper blocks to the fixture.
Dynamic Diverter Setup
Adjust the actuation point of a diverter arm on the fly to accommodate varying package lengths on a packaging line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX75-10S the Right Cylinder?
Choose this 80 mm bore when 50 mm falls short (982N push at 0.5 MPa) but you want to avoid the larger 100 mm footprint (3927N). The 10 mm rear adjustment screw is ideal for product-size changeovers on a line, letting you shift the retract end-stop without machining new hard stops. Because the adjuster acts only as a travel stop and the air cushions handle deceleration, neither will hold the load without live air. For true fail-safe load holding, consider the SAIL or BSAI series.
To match this ISO 15552 interchangeable replacement, specify: 80 mm bore, 75 mm stroke, 10 mm adjustment range, PT G3/8 port thread, SUS420J2 (A) rod material, and the -S magnet option.
Quick checklist
- ✓ 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 SAIJ80AX75-10S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides a push force of 2513N and a pull force of 2268N. It can reach up to 513 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw allows you to shorten the 75 mm nominal stroke by up to 10 mm, creating a 65-75 mm usable travel window. This stopper only sets the end position; it does not lock the load without continuous air pressure.
