About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20S
The AirTAC SAIJ32X800-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel within a 780-800 mm window. The integrated -S magnet enables precise position detection with AirTAC CMSE reed and DMSE electronic sensors.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops during commissioning or product changeover. The rear screw acts purely as a mechanical travel stop and does not hold the load without live air pressure. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ32BX800-20S Is Used
End-Stop Tuning
Dial in the exact 780-800 mm retract position during machine commissioning without physically swapping out long-stroke cylinders.
Product Changeover
Quickly adapt automated lines to new part sizes by adjusting the rear stopper screw to meet new dimensional requirements.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-20S the Right Cylinder?
Choose this 32 mm bore when you need variable end-position tuning within an 800 mm travel window. Because the 800 mm stroke is long and the 12 mm rod is relatively slender, an external guide is highly recommended to prevent excessive side-load wear on the barrel seals.
For load-holding without continuous live air pressure, this cylinder is insufficient because the rear adjuster and air cushions only decelerate the travel end. You must pair it with an external rod lock, a pilot-operated check valve, or switch to an AirTAC SAIL or BSAI clamp-lock cylinder. To match this ISO 15552 interchangeable unit, specify: 32 mm bore, 800 mm stroke, 20 mm adjustment, PT ports, SUS304 rod, and the -S magnet.

- ✓ 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 SAIJ32BX800-20S FAQ
The rear adjuster screw lets you shorten the nominal 800 mm stroke by up to 20 mm, giving a usable travel window of 780-800 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, the push force reaches 80 kgf.
