About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-10
The AirTAC SAIJ32X185-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 185 mm nominal travel by up to 10 mm. This creates a precise 175-185 mm usable window, letting you fine-tune the retract end position at commissioning without adding external stops. It delivers 402 N of push force at 0.5 MPa.
Built with a SUS304 stainless steel rod, this version is well-suited for environments where corrosion resistance is a priority. The extruded aluminum barrel features sensor grooves on both sides, and while this specific SKU lacks a magnet, adding one enables the use of AirTAC CMSE reed and DMSE electronic sensors.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-10 Is Used
End-Position Tuning
Dial in the exact retract distance within the 175-185 mm window during machine commissioning to achieve perfect alignment without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slightly different product sizes on a packaging or handling line.
Corrosion-Resistant Actuation
Leverage the SUS304 stainless steel rod in light manufacturing tasks where moisture or mild corrosive elements are present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX185-10 the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa; if your application requires less force, a 25 mm bore might suffice, while stepping up to a 40 mm bore yields 628 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers. To match this cylinder for an ISO 15552 replacement, confirm the 185 mm stroke, 10 mm adjustment, PT tapered port thread, and your required mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is under 300 mm, side-load stress on the 12 mm rod is minimal, though external guides are still recommended for heavy lateral loads.
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 SAIJ32BX185-10 FAQ
At a standard 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 185 mm nominal stroke by up to 10 mm, resulting in a 175-185 mm travel window. Note that this adjuster is a stop and not a lock; the cylinder requires live air to hold its position.
