About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-30S
The AirTAC SAIJ32X175-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 175 mm stroke that can be fine-tuned down by up to 30 mm, giving you a precise 145-175 mm usable travel window during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threading with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts strictly as a travel stop for end-position tuning, not a load lock.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32BX175-30S Is Used
Product Changeovers
Quickly dial in the 145-175 mm travel window during format changes on packaging lines without swapping the cylinder.
End-Stop Calibration
Fine-tune the retract end position during machine commissioning to achieve precise sensor triggering without external stops.
Variable Sorting
Adjust the stroke on the fly to handle different package sizes on a conveyor diverter system.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX175-30S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when you need to dial in exact end positions without adding external stops or swapping components. Conversely, if you need higher clamping forces, the 50 mm bore provides 982 N. The integrated rear screw allows rapid product changeovers on the line. Remember that the adjuster and air cushions only decelerate the load; they do not hold position without live air. For dead-load holding, consider an external pilot-operated check valve or the SAIL lock cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 175 mm stroke, 30 mm adjustment range, PT port thread, and the -S magnet requirement. The SAIJ utilizes a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Because the 175 mm stroke is under 300 mm, side-load risks are moderate, but the 12 mm rod diameter still requires external guiding 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 Adjustable Cylinder SAIJ32 SAIJ32BX175-30S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm from the 175 mm nominal length, creating a 145-175 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
