About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-30
The AirTAC SAIJ80X175-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the rear screw, you achieve a usable travel window of 145-175mm, allowing precise end-position tuning at commissioning without adding external stops.
This variant uses a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster acts strictly as a travel stop for deceleration alongside the standard air cushions; it does not lock 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 SAIJ80BX175-30 Is Used
Machine Changeover
Quickly adapt the 145-175mm travel window during product size transitions without physically replacing the actuator.
Variable End Stops
Fine-tune the retraction point on packaging lines to accommodate varying package lengths on the fly.
Setup Calibration
Dial in the exact end position during initial commissioning using the rear stopper rather than shimming mounts.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX175-30 the Right Cylinder?
The 30mm adjustment range is ideal for product-size changeovers on a line, letting you dial in the exact 145-175mm stroke on the fly instead of swapping to a fixed-length SAI cylinder. For load-holding without continuous air pressure, integrate an external rod lock or select a SAIL or BSAI model instead.
When replacing an ISO 15552 cylinder, match the 80mm bore, 175mm nominal stroke, 30mm adjustment, PT G3/8 port, and your required mounting bracket. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR options. Since this unit lacks the -S magnet option, it cannot host CMSE or DMSE sensors.
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 SAIJ80BX175-30 FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to trim the effective stroke by up to 30mm. This creates a usable travel window of 145-175mm from the 175mm nominal stroke, enabling fine-tuning of the end position without changing the cylinder.
