About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-20S
The AirTAC SAIJ32X30-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a SUS420J2 stainless steel rod and a built-in magnet for position detection. By turning the external stopper screw, you can fine-tune the effective travel down from its 30 mm nominal stroke, creating a precise 10-30 mm usable stroke window without adding external stops.
It is designed for rapid commissioning and product changeovers, letting you dial in the exact retract end-position on the fly. The rear adjuster acts strictly as a travel stop for deceleration, not a lock, so live air pressure is required to hold the load.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32AX30-20S Is Used
Machine Changeovers
Dial in the retract position within the 10-30 mm travel window during product size transitions without swapping out the cylinder.
End-Position Tuning
Fine-tune the exact end-of-stroke stop at commissioning to perfect pick-and-place accuracy on the assembly line.
Sensor-Ready Testing
Leverage the built-in -S magnet with CMSE reed or DMSE solid-state sensors to verify the adjusted travel endpoints.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX30-20S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your machine setup requires variable end-stops or frequent product-size changeovers. Conversely, if you need to reduce the stroke below 10 mm, you would need a different base cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 30 mm stroke, 20 mm adjustment range, PT G1/8 port, and the -S magnet requirement. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster does not function as a brake.
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 SAIJ32AX30-20S FAQ
It operates at speeds ranging from 30 to 800 mm/s.
The rear adjuster screw allows you to shorten the nominal 30 mm stroke by up to 20 mm, resulting in a usable travel window of 10 to 30 mm. It acts as a physical stop and does not lock the load without air pressure.
