About the Airtac SAI32 Standard Cylinder SAI32BX50S
The AirTAC SAI32X50-S is a double-acting ISO 15552 profile cylinder engineered for compact automation. It delivers a push force of 402 N at 0.5 MPa, making it well-suited for short 50 mm stroke movements in tight machinery layouts.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet for CMSE or DMSE sensor integration. The extruded aluminum barrel includes dual sensor grooves, providing flexible switch mounting without requiring extra hardware.

Where the Airtac SAI32 Standard Cylinder SAI32BX50S Is Used
Small Part Ejection
Provides reliable 402 N push force to eject small machined components from a fixture in confined spaces.
Package Diverting
Actuates a short-stroke diverter arm to route lightweight packages on a high-speed sorting line.
Clamp Actuation
Drives a compact clamping mechanism to hold thin materials securely during a light machining process.
Is the Airtac SAI32 Standard Cylinder SAI32BX50S the Right Cylinder?
Choose this 32 mm bore when a 25 mm bore lacks the necessary thrust and a 40 mm bore (628 N at 0.5 MPa) is physically too large for the envelope. The 50 mm stroke is optimal for rapid clamping or ejecting tasks. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for heavy off-center loads.
As a standard double-acting actuator, this cylinder relies on continuous air pressure to maintain its position. If your cycle requires the rod to hold a load during a pressure loss or valve centering, specify the SAIL variant with an air-released lock or integrate an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, using a PT G1/8 port, and supports standard mountings like LB foot or FA flange.

- ✓ 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 SAI32BX50S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X50-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can drop it into existing mounting footprints using standard LB, FA, or TC accessories without modifying the plate.
