About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-10S
The AirTAC SAIJ80X225-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513 N push force at 0.5 MPa, stepping up to 4523 N at 0.9 MPa. The built-in -S magnet enables position feedback via CMSE reed and DMSE electronic sensors, which seat neatly into the dual-side extruded aluminum barrel grooves.
This specific SKU provides a 215 to 225 mm usable travel window, allowing you to dial back the nominal 225 mm stroke by up to 10 mm. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning. It does not lock the load without live air pressure; for true holding force, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-10S Is Used
Changeover Calibration
Dial in the 215-225 mm travel window precisely during product size changeovers on a packaging line without replacing the cylinder.
End-Position Trimming
Use the 10 mm rear stopper screw to fine-tune the retract end position during machine commissioning, ensuring perfect alignment of the tooling.
Automated Assembly
Leverage the 2513 N push force and CMSE/DMSE sensor compatibility to execute and confirm robust pressing operations in automated cells.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-10S the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N push at 0.5 MPa) is too weak but 100 mm (3927 N) is oversized. The 10 mm adjustment window is ideal for precise end-position tuning during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, retain the 225 mm stroke, 10 mm adjustment, PT tapered port thread, and the -S magnet option.
With a 225 mm stroke, the 25 mm carbon steel rod and M20x1.5 thread provide solid rigidity, but long unsupported strokes still require an external guide to prevent side-load damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ80X225-10S FAQ
The rear adjuster screw lets you shorten the effective travel by up to 10 mm, creating a 215 to 225 mm usable window. It functions as a mechanical stop for end-position tuning and is not a lock; the cylinder still requires live air to hold position.
It provides 2513 N of push force and 2268 N of pull force at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, it delivers up to 513 kgf.
