About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-50
The AirTAC SAIJ32X240-50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 190-240 mm usable travel window, allowing you to dial back the nominal 240 mm stroke by up to 50 mm during commissioning.
This variant uses a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and features PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for easy switch placement. Note that the rear adjuster acts strictly as a travel stop for end-position tuning; it does not lock or hold the load without continuous live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-50 Is Used
Product Changeovers
Dial in the exact end-position for different package sizes on a packaging line by adjusting the rear stopper from 190 to 240 mm without changing hardware.
Variable End Stops
Create a custom travel window for testing fixtures where the exact insertion depth of a 12 mm rod needs on-the-fly adjustment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-50 the Right Cylinder?
Choose this 50 mm adjustable variant when your application requires frequent product changeovers or variable end-stops without swapping the physical cylinder. Conversely, if you require less adjustment range, a fixed-stroke SAI or a smaller -10 adjuster code would reduce the overall rear length.
Because the 240 mm stroke exceeds 300 mm? No, but at 240 mm it is still relatively compact. However, with a 12 mm rod diameter and M10x1.25 thread, you must ensure the load is guided externally to prevent side-load damage. For any load-holding requirements without live air, this cylinder cannot act as a brake; you would need an external pilot-operated check valve or a SAIL/BSAI locking cylinder. When matching for ISO 15552 interchangeability, confirm the 32 mm bore, 240 mm stroke, 50 mm adjuster, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ32AX240-50 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 50 mm, creating a usable travel window of 190 to 240 mm. It functions as a mechanical stop for end-position tuning and does not hold the load if air pressure is removed.
