About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-40S
The AirTAC SAIJ32X180-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 140 and 180 mm. Delivering 402 N of push force at 0.5 MPa, it integrates a SUS420J2 stainless steel rod (code A) for superior corrosion resistance. The built-in magnet (-S) supports position sensing.
This model utilizes a PT tapered port thread and includes variable air cushions at both ends to decelerate the load. The rear adjuster acts as a mechanical stop to dial in the exact end position during commissioning without adding external stops. It is important to note that this adjuster is not a lock; the cylinder cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-40S Is Used
Machine Changeover
Dial in the exact 140-180 mm stroke needed for different product sizes on a packaging line without swapping out the entire cylinder.
End-Position Tuning
Fine-tune the retract end-stop during commissioning to achieve perfect positioning accuracy without adding external mechanical stops.
Light Assembly Push
Provides 402 N of precise pushing force at 0.5 MPa for light-duty assembly tasks requiring adjustable travel distances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-40S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and a highly variable end-stop. The 40 mm adjustment range is ideal for product changeovers on a machine line, allowing you to shorten the stroke from 180 mm down to 140 mm on the fly. If you need less force, stepping down is not an option below 32 mm, but stepping up to a 40 mm bore provides 628 N of push force. For load-holding without live pressure, consider the SAIL or BSAI series instead of relying on the adjuster.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 180 mm stroke, PT port, and SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Since the stroke is 180 mm, side loads are minimal, but always ensure proper guide alignment. The -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.

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 SAIJ32AX180-40S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 40 mm. This gives you a usable travel window between 140 and 180 mm. It only sets the travel end and does not lock or hold the load without live air pressure.
At 0.5 MPa, it delivers 402 N of push force and 345 N of pull force. The -S option includes a magnet for use with AirTAC CMSE reed switches and DMSE electronic sensors.
