About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-75S
The AirTAC SAIJ80X175-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the nominal 175 mm travel to a minimum of 100 mm. This wide 100-175 mm usable window is ideal for product changeovers where end-position tuning is required without adding external stops.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. Fluid ports are PT tapered thread (G3/8). The rear adjuster acts purely as a travel stop to set deceleration endpoints and does not hold the 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 SAIJ80BX175-75S Is Used
Variable Product Changeover
Leverage the 100-175 mm travel window to rapidly switch end-stops for different sized parts on a single conveyor line without physically swapping cylinders.
Machine Setup Fine-Tuning
Use the rear stopper screw to precisely trim the retraction end-position during commissioning, avoiding the need to add external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-75S the Right Cylinder?
The 75 mm adjustment range is exceptionally wide, allowing a single cylinder to handle multiple product sizes on a shared line. If the machine needs to hold a load statically without continuous air pressure, the standard SAIJ adjuster is insufficient, and you should pivot to an SAIL air-released lock or BSAI clamp-lock cylinder.
To replace an ISO 15552 cylinder, match the 80 mm bore, 175 mm stroke, 75 mm adjustment, PT G3/8 port, and the -S magnet requirement. Mounting options for this series are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-loading on the 25 mm rod is manageable, though an external guide is still recommended for heavy lateral loads.
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 SAIJ80BX175-75S FAQ
The nominal stroke is 175 mm, but the rear adjuster allows you to shorten the effective travel by up to 75 mm. This creates a usable stroke window of 100 to 175 mm for fine-tuning end positions.
