About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-30
The AirTAC SAIJ32X500-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 500 mm travel that can be dialed back by up to 30 mm, giving an effective usable window of 470 to 500 mm. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at a 0.5 MPa operating pressure.
This variant uses a SUS420J2 stainless steel rod (code A) for superior corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, though this specific SKU is supplied without a magnet. It connects via PT tapered G1/8 ports and achieves speeds from 30 to 800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-30 Is Used
Machine Changeover
Dial in the 470-500 mm travel window during product size changes without swapping out the entire cylinder or reworking external stop blocks.
Sorting Diverter
Fine-tune the retract position of a conveyor sorting arm to accommodate varying package dimensions on the fly.
End-Position Tuning
Adjust the rear stopper screw to perfect the end-of-stroke deceleration alongside the built-in 27 mm air cushions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa. If you need greater thrust, stepping up to the 40 mm bore yields 628 N under the same pressure. The 30 mm adjustment range is ideal for fine-tuning the retract end-position during machine commissioning or product changeover without adding external stops, a major advantage over a fixed-stroke SAI cylinder.
Because the 500 mm stroke is substantial for a 32 mm bore, an external guide is strongly recommended to prevent excessive side-loading on the 12 mm rod and M10x1.25 thread. Remember that the rear adjuster is a travel stop, not a locking device; it will not hold the load without live air pressure. For true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552.
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 SAIJ32AX500-30 FAQ
At a 0.5 MPa operating pressure, 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 screw acts as a mechanical stop that allows you to shorten the 500 mm nominal stroke by up to 30 mm, resulting in a usable travel range of 470 to 500 mm. It sets the end position but does not lock the load without continuous air pressure.
