Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 50mm 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 SAUF32X50S-06B
The SAUF32X50S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210 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 makes it shorter than an ISO 15552 cylinder of the same bore. The 1/8" cylinder port and M10x1.25 rod end handle a 402 N push at 0.5 MPa.
The integrated 4M210-06 valve delivers 14 mm2 flow (Cv 0.78) at up to 5 cycles per second. It runs on DC24V via a terminal entry and connects with PU tube Ø8xØ5. Size within the 0.15-0.8 MPa valve window, where the safe working load is roughly 241 N and vertical lift is about 20 kg with a 2:1 margin. The S suffix provides a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF32X50S-06B Is Used
Decentralized Clamping
Drives independent clamping jaws across a large fixture using one DC24V signal per actuator, skipping a central valve manifold.
Inline Diverter Gates
Switches small package routing gates directly at the conveyor edge, saving tubing back to a control cabinet.
Compact Pick-and-Place
Handles short 50 mm transfers in tight assembly cells where the built-in valve cuts installation time.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X50S-06B the Right Choice?
For 50 mm stroke, this 32 mm bore provides 402 N push at 0.5 MPa; step up to a 40 mm bore for 628 N if the load demands it. Confirm the DC24V coil and terminal entry match your supply. The rod retracts when energised but you can reposition the valve to extend on signal. The cylinder body rates to 1.0 MPa, but size force within the 0.15-0.8 MPa valve range. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold a load. Mounting uses AirTAC SC series accessories.
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 SAUF32X50S-06B FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in 4M210-06 valve has 1/8" ports, 14 mm2 flow (Cv 0.78), and runs on DC24V. Although the cylinder body rates to 1.0 MPa, the integrated valve limits the assembled unit to a 0.15-0.8 MPa working range.
By default the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the valve on the cap. This decentralized setup removes the need for a separate remote valve.
