About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-40S
The AirTAC SAIJ32X190-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 190 mm travel by up to 40 mm, creating a precise 150-190 mm usable window. Equipped with a -S magnet for CMSE reed and DMSE electronic sensors, it delivers 402 N of push force at 0.5 MPa and uses a SUS420J2 stainless steel rod for enhanced corrosion resistance.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine setup or product changeovers. It features PT tapered ports (G1/8) and variable air cushions at both ends to decelerate the load. The rear adjuster acts purely as a mechanical travel stop, meaning it will not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-40S Is Used
Product Changeovers
Dial in the 150-190 mm travel window during packaging format changes without physically replacing the cylinder or adding external shims.
End-Position Tuning
Fine-tune the exact retract distance at machine commissioning to perfect a pressing or clamping operation.
Sensor Equipped Setup
Leverage the built-in -S magnet with DMSE electronic sensors to confirm the adjusted end positions in your control system.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-40S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and on-the-fly end-position tuning. If you need greater thrust, stepping up to the 40 mm bore yields 628 N at the same pressure. The adjustable 150-190 mm window is ideal for product-size changeovers, whereas a fixed-stroke SAI cylinder is better suited for dedicated, single-size machinery.
Because this is a 190 mm stroke, you should verify guide alignment to prevent excessive side-loading on the 12 mm rod. For load-holding without continuous air pressure, this cylinder is not a lock; consider an AirTAC SAIL or BSAI clamp-lock cylinder instead. To match this ISO 15552 interchangeable unit, specify the 32 mm bore, 190 mm stroke, 40 mm adjustment, PT ports, and the -S magnet option.
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 SAIJ32AX190-40S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operating at 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 40 mm from the 190 mm nominal stroke, yielding a 150-190 mm usable window. It only sets the travel end and does not lock the load without live air.
