About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-20S
The AirTAC SAIJ32X190-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 190 mm travel by up to 20 mm to achieve a precise 170-190 mm usable window during commissioning. Delivering 402 N of push thrust at 0.5 MPa, it fits compact pneumatic setups perfectly. The integrated -S magnet supports AirTAC CMSE reed and DMSE solid-state sensors, which seat neatly into the extruded aluminum barrel's dual-side sensor grooves.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. It is important to note that the rear adjuster acts purely as a travel stop to fine-tune the end position without swapping the cylinder; it does not lock or hold the load without live air pressure. For applications requiring position holding, a SAIL or BSAI series cylinder is recommended.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-20S Is Used
Machine Changeover
Fine-tune the 170-190 mm travel window on the fly to accommodate new product dimensions without changing the cylinder.
End-Position Tuning
Dial in the exact retract stop during commissioning to perfect positioning without adding external mechanical stops.
Corrosive Environments
The SUS304 stainless steel rod excels in packaging or light chemical washdown areas where carbon steel would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-20S the Right Cylinder?
Choose this 32 mm bore when your application requires around 402 N of push force at 0.5 MPa, or step up to the 40 mm bore if you need 628 N. An adjustable stroke is ideal here for machine setups requiring variable end-stops or product-size changeovers, negating the need to physically swap out a fixed-stroke SAI cylinder. When replacing an ISO 15552 unit, match the 32 mm bore, 190 mm nominal stroke, 20 mm adjuster, PT port threads, and the -S magnet requirement. Since the travel is 190 mm, ensure proper guidance to prevent excessive side-loading on the rod.
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 SAIJ32BX190-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 190 mm nominal stroke by up to 20 mm, creating a 170-190 mm travel window. It functions as a physical stop for end-position tuning and does not hold the load without live air.
