About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-40S
The AirTAC SAIJ32X290-40-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 290 mm stroke and a 40 mm adjustment range, it provides a usable travel window of 250 to 290 mm. This allows you to dial in the exact retract end-position at commissioning without swapping hardware.
This SKU includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and features a magnet for position sensing. It integrates seamlessly with AirTAC CMSE reed and DMSE solid-state sensors via the dual-side barrel grooves. The PT tapered ports are G1/8, and the standard variable air cushions at both ends handle end-of-stroke deceleration. The rear adjuster acts purely as a travel stop and does not 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 SAIJ32AX290-40S Is Used
Machine Setup & Changeover
Fine-tune the retract distance by up to 40 mm during product size transitions without replacing the cylinder or adding mechanical stops.
Variable End-Stop Positioning
Dial in a precise 250 to 290 mm travel window for light-duty assembly tasks requiring exact endpoint control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-40S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when an application requires precise end-position tuning during machine setup or product changeover, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder. To replace this cylinder, match the 32 mm bore, 290 mm nominal stroke, 40 mm adjuster, PT G1/8 port, and the -S magnet.
Because the 290 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 thread will carry some side load, but an external guide rail is recommended for heavy or off-center loads to prevent premature wear. For applications that must hold a load in place without continuous air pressure, note that this adjuster is not a lock; consider the SAIL or BSAI series instead.
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 SAIJ32AX290-40S FAQ
At 0.7 MPa, the push force increases to 563 N. The operational speed range is 30-800 mm/s.
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm from the 290 mm nominal length, creating a 250 to 290 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
