About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-75
The AirTAC SAIJ32X190-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 115 to 190 mm window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable model lets you dial in the exact retract end-position during commissioning or product changeover without swapping the cylinder or adding external stops. The rear screw acts purely as a travel stop to set deceleration alongside the standard air cushions; it does not hold the load without live air. For true load-holding without pressure, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-75 Is Used
Product Changeover
Rapidly reconfigure the retract distance from 115 to 190 mm on packaging lines handling varying carton sizes without changing the cylinder.
End-Stop Calibration
Dial in the exact end-position during machine commissioning to ensure precise 402 N push placement without adding external mechanical stops.
Variable Positioning
Set custom retract lengths for testing fixtures, allowing flexible stroke endpoints while maintaining the standard ISO 15552 footprint.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX190-75 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa (or 563 N at 0.7 MPa) combined with a highly variable retract distance. If your setup needs greater thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. The 75 mm adjustment range is ideal for machinery that processes multiple product sizes, allowing you to reposition the end-stop rapidly rather than maintaining an inventory of fixed-stroke SAI cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 190 mm nominal stroke, PT port threads, and the required mounting hardware. Because the 12 mm rod and M10x1.25 thread provide limited side-load capacity, always use an external guide if the load is heavy or asymmetric. Note that this unit lacks a magnet, so it cannot host CMSE or DMSE sensors without a different configuration.
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 SAIJ32AX190-75 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 190 mm nominal length, providing a usable travel window of 115 to 190 mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
