About the Airtac SAI32 Standard Cylinder SAI32AX185S
The AirTAC SAI32X185-S is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 185mm stroke. It delivers a push force of 402 N at 0.5 MPa and 563 N at 0.7 MPa, making it well-suited for compact automation tasks requiring moderate thrust over a mid-range distance.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It is equipped with a magnetic piston (-S) compatible with CMSE and DMSE sensor switches, which seat neatly into the dual extruded sensor grooves on the aluminum barrel. The fluid port utilizes a PT tapered thread, and the standard adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI32 Standard Cylinder SAI32AX185S Is Used
Component Ejection
Provides reliable push force to eject small machined parts from a fixture, utilizing the 185mm stroke to clear the machining envelope entirely.
Package Sorting
Actuates a diverter arm on a packaging line, using the magnetic piston and DMSE sensors to confirm stroke position for high-speed sorting.
Pallet Stops
Acts as a pneumatic stop for lightweight pallets arriving at an assembly station, decelerating smoothly at the stroke end via adjustable air cushions.
Is the Airtac SAI32 Standard Cylinder SAI32AX185S the Right Cylinder?
Selecting this 32mm bore model is ideal when your application demands 402 N of push force at 0.5 MPa. If your fixture requires less thrust, stepping down is not an option as 32mm is the smallest standard SAI bore; however, if you need significantly more power, stepping up to the 40mm bore yields 628 N at 0.5 MPa. The 185mm stroke is a standard length, but because it exceeds 150mm, you must account for side-load risks to the rod bearing. Utilizing an external guide rail or a fully guided cylinder will prevent rod bending and premature seal wear.
Because this is a double-acting cylinder, it does not hold its load if air pressure is lost or the valve is centered; the piston will drift. Never rely on the adjustable air cushion as a locking mechanism, as it only decelerates the piston near the stroke ends. For drop-prevention, consider the SAIL variant with an air-released lock. This SAI32X185-S is dimensionally interchangeable per ISO 15552, featuring a PT G1/8 port, and can use standard FA/FB flanges or LB foot mounts.
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.
