About the Airtac SAI32 Standard Cylinder SAI32BX20S
The AirTAC SAI32X20-S is a double-acting ISO 15552 profile cylinder engineered for compact, short-stroke automation. Delivering a push force of 402 N at 0.5 MPa, this unit is tailored for high-cycle positioning tasks where space is restricted. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or chemically exposed environments. Equipped with a magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches housed in the dual side grooves. Fluid connections use PT tapered threads, ensuring robust, leak-free pneumatic sealing.

Where the Airtac SAI32 Standard Cylinder SAI32BX20S Is Used
Small Part Ejection
Provides rapid 20 mm strokes to eject small molded components from machining centers without occupying excessive fixture space.
Packaging Diverter
Actuates short-stroke gating mechanisms to divert lightweight cartons on high-speed packaging conveyor lines.
Clamp Actuation
Drives compact clamping arms holding delicate workpieces during light assembly or adhesive curing processes.
Is the Airtac SAI32 Standard Cylinder SAI32BX20S the Right Cylinder?
Selecting this 32 mm bore over smaller alternatives makes sense when your application requires the full 402 N push force at 0.5 MPa without operating at maximum pressure limits. If your mechanism demands less than 300 N, stepping down reduces unnecessary air consumption. Conversely, loads exceeding 700 N require stepping up to a 40 mm bore.
Because the 20 mm stroke is very short, rod-bearing bending is negligible, eliminating the need for external guides. However, standard pneumatic cylinders cannot hold position upon loss of air pressure; if your process requires dead-load holding, integrate an external pilot-operated check valve. This cylinder is fully interchangeable with other ISO 15552 cylinders matching the 32 mm bore, 20 mm stroke, PT port, and standard mounting accessories like LB or FA.
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 SAI32BX20S FAQ
At a standard operating pressure of 0.5 MPa, this 32 mm bore cylinder generates a push force of 402 N and a pull force of 345 N. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X20-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other standard 32 mm bore profile cylinders with a 20 mm stroke, provided your mounting hardware and PT port sizes match.
