About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-75
The AirTAC SAIJ32X185-75 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 185 mm stroke that can be fine-tuned down by up to 75 mm, creating a usable travel window of 110 to 185 mm. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads.
This adjustable-stroke design allows you to dial in the exact retract end-position at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-75 Is Used
Product Changeovers
Quickly modify the retract end-stop by up to 75 mm to accommodate varying package lengths on a packaging line without changing hardware.
Machine Setup
Fine-tune the 185 mm stroke during initial commissioning to achieve exact positioning, eliminating the need for external mechanical shims.
Variable End Stops
Ideal for test fixtures requiring a flexible 110-185 mm travel window to test different component sizes or actuation depths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-75 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning within a 110-185 mm travel window. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The generous 75 mm adjustment range is ideal for machines handling frequent product-size changeovers, replacing the need for fixed-stroke SAI cylinders when exact end stops fluctuate.
For an exact ISO 15552 replacement, match the 32 mm bore, 185 mm stroke, 75 mm adjustment, PT port thread, and SUS304 rod material. Note that this model lacks a magnet, so position sensing requires adding an -S suffix to use CMSE reed or DMSE electronic switches. Because the stroke is under 300 mm, side-load risks are moderate, but external guides are still recommended for unsupported loads. For load-holding without live air, consider an external rod lock or the SAIL series instead.

- ✓ 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 SAIJ32BX185-75 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 reduce the nominal 185 mm stroke by up to 75 mm, providing an effective travel range of 110 to 185 mm. It functions as a mechanical stop and does not lock the load without continuous air pressure.
