About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-20S
The AirTAC SAIJ32X600-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 20 mm. This yields a usable 580-600 mm window, letting you dial in the exact retract position at commissioning without swapping the barrel or adding external stops. It delivers 402 N of push force at 0.5 MPa and uses a PT tapered port thread.
This variant includes a magnet for CMSE and DMSE sensors and uses an SUS420J2 stainless steel rod (code A) for improved corrosion resistance. The 12 mm rod and M10x1.25 thread carry modest side loads, but at 600 mm of travel, you should guide the load externally to prevent rod binding. The rear adjuster acts purely as a travel stop and does not lock the load without live air.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-20S Is Used
Machine Changeover
Dial in the 580-600 mm retract position during product size changes without physically swapping the cylinder or adding external mechanical stops.
Long-Stroke Sorting
Handles long linear sorting motions on a line, using the 20 mm adjustment to fine-tune the exact end-of-stroke resting position.
Sensor-Ready Positioning
Leverages the -S magnet for CMSE and DMSE electronic switches to confirm end positions while adjusting the travel window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-20S the Right Cylinder?
Choose this 32 mm bore when you need precise retract positioning over a long 600 mm stroke and standard SAI cylinders fall short on adjustability. If your application requires more thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa, but increases the footprint. The built-in adjuster is perfect for machine changeovers where product sizes vary slightly, replacing the fixed end-stop of a standard SAI cylinder.
Because the stroke is 600 mm, external load guiding is essential to prevent side-loading damage. Remember that the SAIJ rear adjuster and air cushions only decelerate the travel end; they do not hold the load. For true fail-safe load holding without live air pressure, use an external rod lock or explore the SAIL or BSAI cylinder series. This SAIJ model is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ32AX600-20S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster acts as a stopper that lets you shorten the 600 mm nominal stroke by up to 20 mm, creating a 580-600 mm usable travel window. It sets the end position but does not lock the load.
