About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-50
The AirTAC SAIJ32X400-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 350-400 mm. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, allowing straightforward installation of CMSE or DMSE switches if a magnet is added later.
This variant utilizes an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and features PT tapered port threads with a G1/8 connection. The rear stopper allows you to fine-tune the retract position at commissioning without swapping the cylinder or adding external stops. Remember that this adjuster acts only as a travel stop, not a lock, so it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-50 Is Used
Product Changeovers
Quickly dial in the 350-400 mm travel window during format changes on packaging lines without swapping hardware.
Variable End Stops
Provides adjustable retract positions for diverters or pushers handling different carton sizes on a conveyor.
Commissioning Fine-Tune
Allows precise end-position tuning during machine setup to avoid mechanical crashes and optimize motion.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX400-50 the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa; step up to a 40 mm bore if you need 628 N to overcome higher friction. The 50 mm adjustment range is perfect for product changeovers on a line, letting you dial in the exact end-stop without changing the fixed stroke of a standard SAI cylinder. To match this ISO 15552 footprint, specify the 32 mm bore, 400 mm stroke, PT port, and your required mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because the 400 mm stroke is relatively long for a 12 mm rod, external guidance is recommended to prevent excessive side-loading and premature seal wear. For applications requiring the load to be held mechanically without continuous air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ32AX400-50 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 563 N.
The rear adjuster screw lets you shorten the 400 mm nominal stroke by up to 50 mm, creating a 350-400 mm travel window. It functions as a physical stop to set the end position and does not lock the load without live air.
