About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX95-50S
The AirTAC SAIJ32X95-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 95 mm stroke that can be dialed back by up to 50 mm, creating a highly flexible 45-95 mm usable travel window for precise end-position tuning during commissioning.
This variant features an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and includes a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster functions strictly as a mechanical stop to set the retract position, not as a lock to hold the 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 SAIJ32AX95-50S Is Used
Product Changeover
Dial in the 45-95 mm travel window during format size changes on a packaging line, avoiding the need to physically swap cylinders for different package lengths.
End-Stop Tuning
Fine-tune the exact retract position during machine commissioning using the rear screw, allowing perfect alignment of delicate 32 mm bore tooling without external shims.
Sensor-Ready Positioning
Leverage the built-in -S magnet alongside CMSE or DMSE switches in the dual sensor grooves to confirm the adjusted end-of-stroke position in automated assemblies.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX95-50S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end stops or frequent product-size changeovers without swapping the entire cylinder or adding external stops. If your application demands greater thrust, stepping up to a 40 mm bore increases the 0.5 MPa push force to 628 N, whereas smaller or fixed-stroke needs are served by the standard SAI series. For holding a load without continuous air pressure, a plain SAIJ is insufficient since the rear adjuster is only a travel stop; consider an AirTAC SAIL or BSAI locking cylinder instead.
To achieve a true ISO 15552 replacement match, confirm the 32 mm bore, 95 mm stroke, 50 mm adjustment range, PT tapered port threads, and the -S magnet option. This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The 12 mm rod and M10x1.25 thread handle moderate side loads well, though any stroke approaching 300 mm or beyond would require an external guide to prevent rod bending.

- ✓ 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 SAIJ32AX95-50S FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 95 mm nominal stroke by up to 50 mm, providing a usable travel window of 45 to 95 mm. It only sets the end position and does not lock the load without live air pressure.
