About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-50S
The AirTAC SAIJ32X450-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 450 mm stroke that can be fine-tuned down by up to 50 mm, creating a precise 400-450 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the rear adjuster acts purely as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-50S Is Used
Product Changeover
Dial in the 400-450 mm travel window during format size changes on packaging lines, using the rear stopper to set exact end positions without changing hardware.
Machine Commissioning
Fine-tune the final retract position during initial setup to clear mechanical obstructions, absorbing minor dimensional variances directly at the cylinder.
Lightweight Diverting
Actuate diverter arms or gates with 402 N of push force, adjusting the stroke length on the fly to accommodate different package sizes on the belt.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-50S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N push force at 0.5 MPa but needs on-the-fly end-position tuning without swapping cylinders or adding external stops. If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N. Conversely, if you only need a fixed 450 mm stroke without commissioning adjustments, the standard SAI model is a simpler choice.
Because the 450 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread should be paired with an external guide to prevent excessive side-loading. To hold a load securely without live air pressure, you must use an external rod lock or pilot-operated check valve, as the SAIJ adjuster and air cushions do not function as brakes. For a direct ISO 15552 replacement, match the 32 mm bore, 450 mm stroke, 50 mm adjustment, PT tapered port, and -S magnet.
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 SAIJ32AX450-50S 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 a maximum 0.9 MPa, the push force increases to 724 N.
The rear adjuster acts as a mechanical stop that trims the effective travel. For this 450 mm nominal stroke model, you can reduce the stroke by up to 50 mm, resulting in a usable travel window of 400-450 mm. It only sets the end position and does not lock the load.
