About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-20S
The AirTAC SAIJ32X180-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 180 mm stroke that can be dialed back by up to 20 mm, yielding a precise 160-180 mm usable travel window for exact end-position tuning during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits compact automation setups requiring moderate thrust.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads ensure a tight, reliable pneumatic connection. The rear adjuster acts purely as a mechanical stop to set the retract end position, not as a lock to hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-20S Is Used
Machine Changeover
Quickly fine-tune the 160-180 mm retract end-position during product size changes on a packaging line without replacing the cylinder or adding external stops.
Variable End-Stops
Dial in the exact pusher distance on a sorting conveyor, using the rear screw to compensate for mechanical wear or varying package dimensions.
Commissioning Calibration
Set precise end-of-travel limits during initial machine setup, leveraging the 20 mm adjustment window to perfect tooling alignment before locking down the position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-20S the Right Cylinder?
Choose this 32 mm bore when your application requires roughly 402 N of push force at 0.5 MPa. If your process demands greater thrust, stepping up to the 40 mm bore yields 628 N, whereas dropping to a smaller bore would compromise the necessary actuation power. The adjustable 160-180 mm stroke is ideal for machine setups requiring variable end-stops or product changeovers, avoiding the need to physically swap cylinders or bolt on external stopper blocks.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using the SAIJ subset of accessories: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Since the 180 mm stroke is under 300 mm, side-load stress is minimal, but the 12 mm rod and M10x1.25 thread still require standard alignment to prevent premature seal wear. Remember that the rear adjuster is a travel stop, not a brake; for true load-holding without live air, consider an AirTAC SAIL or BSAI series 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 SAIJ32AX180-20S FAQ
At a 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operating at 0.7 MPa, the push force increases to 563 N.
The SAIJ32X180-20-S has a nominal 180 mm stroke, but the external rear adjusting screw allows you to shorten the effective travel by up to 20 mm. This creates a 160-180 mm adjustable travel window, letting you fine-tune the end position at commissioning without changing the cylinder itself.
