About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50S
The AirTAC SAIJ32X230-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 230 mm nominal stroke that can be dialed back by up to 50 mm, creating a precise 180-230 mm usable travel window for product changeovers. Delivering 402 N of push force at 0.5 MPa, it handles lighter-duty positioning tasks effectively.
This variant includes an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and carries a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and the rear stopper allows mechanical end-position tuning without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50S Is Used
Product Changeover
Dial in the 180-230 mm travel window during format changes without physically swapping cylinders or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract stroke by up to 50 mm at commissioning to perfect the resting position of delicate tooling.
Sensor-Ready Actuation
Leverage the built-in magnet for CMSE or DMSE switches to confirm the adjusted end position in automated control systems.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with on-the-fly stroke trimming; step up to the 40 mm bore if your application requires 628 N. The adjustable 180-230 mm window is ideal for machines running multiple product sizes, letting you fine-tune the retract end at commissioning rather than swapping a fixed-stroke SAI cylinder. Because the 230 mm stroke exceeds 300 mm? No, but for any extended stroke, ensure external guides support the load to prevent rod binding.
For ISO 15552 replacement matching, specify bore 32, stroke 230, adjustment 50, PT tapered port thread, and the -S magnet. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for positive load-holding without pressure, consider an external rod lock or the SAIL/BSAI series. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ32AX230-50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from its 230 mm nominal length down to 180 mm. It only sets the travel end and does not lock the load without live air pressure.
