About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-40S
The AirTAC SAIJ32X65-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 65 mm stroke that can be dialed back by up to 40 mm, yielding a 25-65 mm usable travel window for precise end-position tuning.
This variant includes a magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors, which seat directly into the dual-side sensor grooves on the extruded aluminum barrel. It features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance over standard carbon steel, and uses PT tapered port threads. The rear adjuster acts strictly as a travel stop to decelerate the end of stroke; it is not a lock, so the cylinder cannot hold a load without 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 SAIJ32AX65-40S Is Used
Product Changeover
Quickly fine-tune the 25-65 mm travel window during line changeovers to accommodate different product lengths without replacing the cylinder.
Machine Setup
Dial in the exact retract end-position at commissioning using the rear stopper, eliminating the need to machine external spacers for the 32 mm bore.
Variable End Stops
Adjust the effective stroke on the fly for testing different sensor positions or clamping depths using the integrated CMSE/DMSE magnet track.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-40S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires variable end-stops for machine setup or product changeover, allowing you to trim the 65 mm travel down to 25 mm without swapping the cylinder or adding external stops. For applications needing true load-holding without continuous air pressure, consider the related SAIL (air-released lock) or BSAI (clamp-lock) cylinders instead of relying on the SAIJ adjuster.
To match this exact configuration for an ISO 15552 dimensional replacement, specify the 32 mm bore, 65 mm stroke, 40 mm adjustment range, PT port threads, SUS420J2 rod material, and the -S magnet option. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ32AX65-40S FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective travel from the nominal 65 mm down to as little as 25 mm, providing a 40 mm adjustment window. It only sets the travel end and does not lock or hold the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, the push force reaches 801 N.
