About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30S
The AirTAC SAIJ32X180-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 150-180 mm usable travel window, allowing you to dial back the nominal 180 mm stroke by up to 30 mm during commissioning without swapping out the unit. Delivering 402 N of push force at 0.5 MPa, it is built for lighter-duty tasks requiring exact end-position tuning.
This variant features a SUS420J2 stainless steel rod for improved corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster functions purely as a travel stop, not a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30S Is Used
Machine Setup Calibration
Dial in the exact 150-180 mm retract position during initial machine commissioning without adding external stopper hardware.
Product Changeover
Quickly adjust the end-stop by up to 30 mm when running a new product size on the line, minimizing downtime.
Light Assembly Positioning
Utilize the 402 N push force to move small components, relying on the rear screw to set precise final placement.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30S the Right Cylinder?
Choose this 32 mm bore when your application needs 402 N of push force at 0.5 MPa; stepping down is not an option, but moving up to a 40 mm bore yields 628 N if your payload increases. An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune the retract end-position on product changeovers rather than machining external stop blocks. For load-holding without live air pressure, this cylinder is insufficient—the rear screw is only a stop—so consider an AirTAC SAIL or BSAI series instead.
As an ISO 15552 interchangeable cylinder, this SKU is specified by its 32 mm bore, 180 mm stroke, 30 mm adjustment range, PT tapered G1/8 port, and -S magnet. With an 180 mm stroke, side loads remain manageable, but always ensure proper guiding for rigid 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 SAIJ32AX180-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the effective stroke from 180 mm down to 150 mm. It acts as a mechanical stop to fine-tune the retract position, but it does not hold the load without live air pressure.
