About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-20S
The AirTAC SAIJ32X250-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 250 mm nominal stroke that can be fine-tuned down by up to 20 mm, creating a precise 230-250 mm usable travel window for commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. You can mount CMSE reed or DMSE electronic switches directly into the sensor grooves on both sides of the extruded aluminum barrel. The PT G1/8 port and integrated adjustable air cushions at both ends ensure reliable deceleration across its 30-800 mm/s speed range.

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 SAIJ32BX250-20S Is Used
Changeover Dial-In
Quickly adjust the 230-250 mm travel endpoint during product size changeovers on a packaging line without replacing the cylinder.
End-Stop Calibration
Fine-tune the final retraction position during machine commissioning to avoid mechanical interference and achieve exact placement.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for light-force pushing and pulling tasks in environments requiring high corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-20S the Right Cylinder?
Select this 32 mm bore when an application requires exact end-position tuning without swapping hardware; stepping up to a 40 mm bore raises push force to 628 N at 0.5 MPa. Choose the SAIJ adjustable format over a fixed SAI cylinder when you need a variable end-stop to dial in a specific 230-250 mm retraction point during machine setup. Because the stroke is 250 mm, ensure external guidance is used to prevent excessive side-loading on the 12 mm rod.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 32 mm bore, 250 mm stroke, 20 mm adjustment, PT G1/8 port, and -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX250-20S FAQ
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 250 mm nominal stroke by up to 20 mm, providing a usable travel window of 230 to 250 mm. It acts as a mechanical stop and does not lock the load without continuous air pressure.
