About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-20S
The AirTAC SAIJ32X290-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that creates a usable travel window of 270 to 290 mm. This unit includes a SUS304 stainless steel rod for corrosion resistance and a magnet for CMSE reed and DMSE electronic sensors.
The rear adjustment screw allows you to fine-tune the end position during commissioning without adding external stops. Because the stroke is 290 mm on a 12 mm rod, you should use an external guide to prevent side-load damage. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ32BX290-20S Is Used
Commissioning End-Stop Tuning
Dial in the exact 270 to 290 mm travel distance during machine setup without swapping out the entire cylinder or adding external stopper blocks.
Product Size Changeover
Adapt the cylinder stroke on packaging lines when product dimensions change, using the 20 mm rear adjustment screw to match new formats quickly.
Corrosion-Resistant Actuation
Leverage the SUS304 stainless steel rod in environments requiring higher corrosion resistance while maintaining standard ISO 15552 mounting dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-20S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers, whereas a fixed SAI cylinder is better for static, repetitive cycles.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. This SAIJ32X290-20-S features PT tapered ports and a 12 mm rod; with a 290 mm stroke, an external guide is necessary to manage side loads.

- ✓ 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 SAIJ32BX290-20S FAQ
At 0.7 MPa, the push force increases to 563 N.
The nominal stroke is 290 mm, but the built-in rear adjuster allows you to shorten the effective travel by up to 20 mm. This creates an adjustable usable window of 270 to 290 mm to fine-tune the end position without changing the cylinder.
