Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 400mm 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 SAUF32X400-06B
The SAUF32X400-06B is a double-acting profile-type 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 unit of the same bore, and it mounts with AirTAC SC-series accessories. The cylinder port is 1/8" and the rod end is M10x1.25.
Operating within the valve's 0.15-0.8 MPa window, this 32 mm bore delivers 402 N push and 345 N pull at 0.5 MPa. The 4M210-06 valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and handles 5 cycles/sec. The DC24V coil offers 3.0 W, IP65 protection, and a 0.05 s response. For sizing, expect a safe working load around 241 N, or a vertical lift of roughly 20 kg with a 2:1 margin. Because this 400 mm stroke exceeds 300 mm, use external guides to prevent rod bending.

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 SAUF32X400-06B Is Used
Decentralized Clamping
Ideal for a multi-station clamping fixture where running individual tubes back to a central manifold is impractical, letting this 32 mm actuator switch itself locally.
Inline Diverting
Perfect for a short-stroke diverter gate on a packaging line, using the integrated 4M210 valve to cycle at up to 5 Hz without extra plumbing.
Compact Ejection
Suits a machine ejection station needing a compact profile cylinder, saving manifold space by driving the 400 mm stroke directly from one DC24V signal.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-06B the Right Choice?
When sizing, compare neighboring bores: a 40 mm bore yields 628 N push at 0.5 MPa versus this 32 mm bore's 402 N. Confirm the DC24V terminal entry and PT threads match your control setup. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Size force strictly within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve routes air and does not lock the load; add an external rod lock or pilot-operated check valve for holding. At 400 mm stroke, support the load externally to avoid rod bending. This SKU lacks the S suffix for a magnet, so it cannot accept a magnetic switch.
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 SAUF32X400-06B FAQ
It generates 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) with a DC24V coil. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
The 5/2 valve routes air but does not lock the piston, so you need an external rod lock or pilot-operated check valve to hold a load. The default action retracts the rod when energized, but you can reposition the valve to extend on signal instead.
