About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-75S
The AirTAC SAIJ80X175-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 175 mm travel by up to 75 mm. This creates a highly flexible 100-175 mm usable stroke window, perfect for dialing in exact end positions during machine commissioning without swapping out the physical unit.
This variant features an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It operates at speeds between 30-800 mm/s and uses a G3/8 port with PT tapered threading for secure pneumatic connections.

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 SAIJ80AX175-75S Is Used
Machine Changeover
Quickly reconfigure the retract end-stop for different product lengths on a packaging line using the 75 mm adjustment window.
Commissioning Calibration
Fine-tune the 175 mm stroke down to a precise 100 mm minimum during setup without machining external stopper blocks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-75S the Right Cylinder?
The generous 75 mm adjustment range is ideal for product-size changeovers on a line, letting you shift the retract stop dynamically rather than installing external stops. Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a locking device; the cylinder cannot hold a load without live air. For true load-holding, consider an AirTAC SAIL or BSAI cylinder.
When integrating this model, note that it supports a specific subset of ISO 15552 mounting hardware: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It deliberately omits FB, CA, CB, and CR mounts. The 25 mm rod diameter and M20x1.5 rod thread provide substantial rigidity, but because the stroke approaches 175 mm, ensure you use an external guide to prevent excessive side-loading on the rod. This unit is dimensionally interchangeable with ISO 15552 cylinders of the same bore and stroke.

- ✓ 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 SAIJ80AX175-75S FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear external adjuster screw lets you mechanically shorten the effective stroke from its nominal 175 mm down to a minimum of 100 mm. This creates a 100-175 mm usable travel window for fine-tuning end positions without replacing the cylinder.
