Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 500mm stroke and a built-in 4M210-06 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-06B
The SAUF32X500S-06B is a double-acting profile-type cylinder with a built-in AirTAC 4M 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 32mm bore, 12mm rod, M10x1.25 rod thread, and 1/8" cylinder port.
Operating within the 0.15-0.8 MPa valve window, it delivers 402N push at 0.5MPa. The integrated 4M210-06 valve provides 14mm2 flow (Cv 0.78) and handles 5 cycles/sec. With a 500mm stroke, the safe working load is roughly 241N (60% of the 0.5MPa push), and vertical lift is about 20kg with a 2:1 margin. The DC24V terminal coil is IP65 rated, and the S suffix denotes a piston magnet for CMSG/DMSG/EMSG switches.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-06B Is Used
Decentralized Clamping
Ideal for distributed machining cells where running individual lines to a central manifold is impractical, using the built-in valve for direct actuator control.
Inline Diverting
Drives sorting gates on packaging lines with a single electrical signal, eliminating the need for nearby valve islands and reducing pneumatic tubing complexity.
Compact Ejector
Fits into tight automated storage retrieval systems, ejecting totes using one coil signal while saving valuable manifold space on the main controller.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-06B the Right Choice?
Size this 32mm bore against the 40mm option (628N push at 0.5MPa) if higher force is needed, or step down if less is required. The 500mm stroke exceeds 300mm, so use external guides to prevent rod bending and manage side loads. Confirm the DC24V terminal entry and PT threads meet your electrical and plumbing specs. The cylinder body rates to 1.0MPa, but size force strictly within the 4M210 valve's 0.15-0.8MPa operating range. The valve can be repositioned to extend-when-energised instead of the default retract. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads securely during air loss.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X500S-06B FAQ
It generates 402N push and 345N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The 5/2 valve only routes air; it is not a load lock. The piston will drift on air loss, so install an external rod lock or pilot-operated check valve for load holding.
