About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-100S
The AirTAC SAIJ80X180-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 80 to 180 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection.
This model uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and features PT tapered port threads with a G3/8 connection. The generous 100 mm adjustment range allows operators to dial in the exact retract end-position during commissioning without swapping hardware. The rear screw acts purely as a travel stop to set deceleration alongside the standard air cushions, so it cannot hold a load without live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-100S Is Used
Product Size Changeovers
Quickly adapt machinery for varying product lengths by dialing the retract position back up to 100 mm, eliminating the need to physically swap cylinders during line changeovers.
Commissioning Fine-Tuning
Perfect for dialing in the exact end-of-stroke position during initial machine setup, allowing engineers to set precise mechanical limits without adding external stopper blocks.
Variable End-Stop Positioning
Ideal for automated assembly lines where the rear stopper screw must accommodate different operational travel distances within the 80 to 180 mm adjustable window.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX180-100S the Right Cylinder?
If your setup only needs 1374 N at 0.5 MPa, stepping down to a 50 mm bore saves space, but the SAIJ80X180-100-S is unmatched for frequent product-size changeovers. Because the nominal stroke is 180 mm, side-loading is minimal, but always ensure the M20x1.5 rod thread is properly aligned.
The rear adjuster is a mechanical stop, not a locking device; for load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. To match this exact ISO 15552 replacement, specify an 80 mm bore, 180 mm stroke, 100 mm adjustment, PT G3/8 port, and the -S magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ80AX180-100S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to trim the effective stroke within an 80 to 180 mm travel window. It acts as a mechanical stop to set the end position, but it is not a lock and will not hold the load without continuous air pressure.
