About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-20S
The AirTAC SAIJ32X450-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 20mm adjustment range, allowing you to fine-tune the effective travel window from 430 to 450mm during commissioning without swapping hardware.
This unit features a SUS420J2 stainless steel rod for improved corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It uses a G1/8 port and M10x1.25 rod thread, offering a robust 30-800mm/s speed range for precision actuation.

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 SAIJ32AX450-20S Is Used
Machine Changeover
Dial in the 430-450mm stroke window during product size transitions to set new end positions rapidly without mechanical modifications.
Precision End-Stop Tuning
Use the 20mm rear adjuster to fine-tune the exact retraction point during commissioning, absorbing mechanical tolerances in the fixture.
Variable Length Indexing
Act as a movable stop on a conveyor line where package lengths vary, adjusting the stop distance by up to 20mm on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-20S the Right Cylinder?
The adjustable stroke is selected over a fixed SAI cylinder when you need a variable end-stop to accommodate product changeovers or to dial in exact positioning without adding external stops. At 450mm of travel, the M10 rod thread is relatively slender, so an external guide is recommended to prevent side-load binding.
For load-holding without live air pressure, note that the rear adjuster is strictly a travel stop, not a lock. You would need to look at the SAIL or BSAI series for true pneumatic locking. This SAIJ32X450-20-S is dimensionally interchangeable per ISO 15552 and is configured with PT tapered port threads, a Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set, and a magnet for CMSE/DMSE sensors.

- ✓ 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 SAIJ32AX450-20S FAQ
At the maximum 1.0MPa pressure, it can deliver up to 82kgf.
The rear adjuster acts as a stopper that lets you shorten the nominal 450mm stroke by up to 20mm, creating a usable travel window of 430-450mm. It only sets the travel end and does not lock or hold the load without live air pressure.
