About the Airtac SAI32 Standard Cylinder SAI32X20
The AirTAC SAI32X20 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and 20mm stroke. It provides 402N of push force at 0.5 MPa, making it well-suited for short-stroke clamping and ejection tasks. The extruded aluminum barrel omits tie rods for a clean exterior.
This configuration ships with a standard carbon steel piston rod and PT tapered port threads. Because it lacks a magnet, position sensing requires external switches. For higher temperature environments up to 70 C, alternative TPU or Viton H seals are available, while the SAIL variant adds an air-released lock for fail-safe holding.

Where the Airtac SAI32 Standard Cylinder SAI32X20 Is Used
Short-Stroke Clamping
Ideal for securing lightweight workpieces during machining or assembly operations requiring 402N of force.
Package Ejection
Provides rapid 20mm stroke ejection of small components or packaging materials off conveyor lines.
Valve Actuation
Delivers reliable linear motion for actuating small mechanical valves and process equipment.
Is the Airtac SAI32 Standard Cylinder SAI32X20 the Right Cylinder?
Choose this 32mm bore when 402N at 0.5 MPa is sufficient for your motion requirements. If your application demands greater thrust, stepping up to the 40mm bore yields 628N. Conversely, if you need to hold a load statically without continuous air pressure, the standard SAI will drift upon pressure loss; you must specify the SAIL lock or BSAI clamp-lock variant.
Being a genuine ISO 15552 profile cylinder, it serves as a direct replacement for any standard 32mm bore, 20mm stroke, PT port configuration. Mounting accessories include LB foot brackets, FA/FB flanges, and TC trunnions. Add the -S suffix if you require integrated CMSE or DMSE sensors.
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 SAI32X20 FAQ
At an operating pressure of 0.5 MPa, the SAI32X20 generates 402N of push force and 345N of pull force.
Yes, the SAI32X20 is a profile-barrel ISO 15552 cylinder, meaning its mounting interface and dimensions are fully interchangeable with other ISO 15552 standard cylinders of the same bore and stroke.
