About the Airtac SAI32 Standard Cylinder SAI32BX185S
The AirTAC SAI32X185-S is a double-acting ISO 15552 profile cylinder engineered for compact automation, delivering a push force of 402 N at 0.5 MPa. Its 185 mm stroke provides the exact mid-range extension needed for precise assembly tasks. This variant includes a piston magnet for direct compatibility with CMSE and DMSE sensor switches mounted in the barrel's dual grooves.
Built with a SUS304 stainless steel rod (code B), this unit offers superior corrosion resistance compared to standard carbon steel, making it ideal for harsher manufacturing settings. It utilizes PT tapered port threads and adjustable air cushions at both ends to absorb impact energy smoothly.

Where the Airtac SAI32 Standard Cylinder SAI32BX185S Is Used
Compact Component Placement
Ideal for electronics lines where the 185 mm stroke pushes delicate parts into testing fixtures with 402 N of force at 0.5 MPa.
Light Package Sorting
The dual sensor grooves allow precise position detection for diverting small parcels along high-speed distribution conveyors.
Corrosive Material Handling
The SUS304 stainless steel rod resists moisture in food packaging or washdown environments better than standard carbon steel.
Is the Airtac SAI32 Standard Cylinder SAI32BX185S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa but lacks the physical envelope for a 40 mm cylinder, which offers 628 N. For lighter duties needing only 345 N of pull force, a smaller bore might be considered, but the 32 mm class often provides the best balance of speed and footprint. Because the stroke is 185 mm, standard mounting accessories like LB foot brackets or FA flanges are fully supported per the ISO 15552 interface.
If your machinery loses air pressure, this cylinder cannot hold its load in place and will drift. For vertical or suspended loads requiring fail-safe holding, select the SAIL variant with an air-released lock or integrate an external pilot-operated check valve.
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 SAI32 Standard Cylinder SAI32BX185S FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. It can reach a maximum theoretical force of 82 kgf at 1.0 MPa.
Yes, the SAI32X185-S is dimensionally interchangeable per ISO 15552. You can swap it into existing foot, flange, or clevis mounts designed for standard 32 mm profile cylinders.
