About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-100
The AirTAC SAIJ80X175-100 is a double-acting ISO 15552 profile cylinder engineered with a rear stroke adjuster, allowing you to dial back the nominal 175 mm travel by up to 100 mm. This creates a highly flexible 75 to 175 mm usable window, eliminating the need to swap hardware during product changeovers. It delivers robust thrust, pushing with 4523 N and pulling with 2268 N at 0.9 MPa.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options are comprehensive yet specific to this series: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX175-100 Is Used
Product Changeovers
Quickly reconfigure the 75-175 mm stroke window on packaging lines handling varying container sizes without replacing the cylinder.
Machine Setup
Fine-tune the exact end-of-stroke position during commissioning to perfect pressing or clamping force without adding external stops.
Variable End Stops
Achieve precise mechanical positioning for assembly stations where multiple part lengths are processed on the same fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-100 the Right Cylinder?
The 100 mm adjustment range is ideal for prototyping or lines running multiple product sizes, allowing you to set variable end-stops on the fly instead of machining external stopper blocks.
Because the 175 mm stroke is under the 300 mm threshold, side-load risks are moderate, but the 25 mm SUS304 rod still requires alignment to prevent premature seal wear. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder cannot hold a load without live air. For load-holding requirements without continuous pressure, consider an external pilot-operated check valve or the AirTAC SAIL locking cylinder. This SKU is dimensionally interchangeable per ISO 15552.
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 SAIJ80BX175-100 FAQ
At 0.5 MPa, the push force is 2513 N.
The rear adjuster screw allows you to shorten the 175 mm nominal stroke by up to 100 mm, providing a usable travel window of 75 to 175 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
