About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-100S
The AirTAC SAIJ80X175-100-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 175 mm stroke that can be dialed back by up to 100 mm, creating a wide 75-175 mm usable travel window for highly flexible end-position tuning.
This variant includes a magnet for position sensing using CMSE reed or DMSE solid-state switches. It features a SUS420J2 stainless steel rod for corrosion resistance and PT tapered port threads. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, while the rear stopper screw allows you to trim the retract end without adding external physical stops.

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 SAIJ80AX175-100S Is Used
Product Changeover
Dial the stroke back from 175 mm to 75 mm instantly on the factory floor when switching to a shorter workpiece, eliminating the need to physically swap cylinders.
End-Position Trimming
Use the rear stopper to precisely set the retract end-position during machine commissioning, absorbing minor mechanical setup variations without external shims.
Variable End Stops
Ideal for automated lines requiring multiple stroke lengths within the 100 mm adjustment window, allowing a single cylinder to handle diverse actuation depths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-100S the Right Cylinder?
Choose this 80 mm bore when your application requires pushing 3518 N at 0.7 MPa, offering a clear step up from the 63 mm bore which provides 2182 N. The 100 mm adjustment range is ideal for machinery that frequently processes different product sizes, allowing you to fine-tune the retract distance during changeovers rather than swapping the entire cylinder. To step up to higher force, the 100 mm bore yields 5497 N at the same pressure.
Because the 175 mm stroke falls under the 300 mm threshold, side-load risks are moderate, but an external guide is still recommended for heavy lateral loads. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. For a direct ISO 15552 replacement, match the 80 mm bore, 175 mm stroke, PT G3/8 ports, the -S magnet, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ80AX175-100S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm, providing a usable travel window between 75 and 175 mm. The adjuster acts as a mechanical stop on the retract end and does not lock the load without live air pressure.
It operates at speeds between 30 and 800 mm/s.
