Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-06B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 350mm 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 SAUF32X350S-06B
The SAUF32X350S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 unit of the same bore. It features a piston magnet for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, it generates 402 N push and 345 N pull at 0.5 MPa. A practical safe working load is roughly 241 N, with a vertical lift capacity of about 20 kg at a 2:1 margin. The integrated valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and cycles up to 5 times per second. The cylinder port is 1/8" PT, using PU tube Ø8xØ5.

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 SAUF32X350S-06B Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station uses one coil signal to actuate independently without a central manifold.
Inline Divert Gate
Perfect for a conveyor divert gate that requires a self-contained actuator, saving tubing runs across a long machine frame.
Package Stopper
Suits a decentralized packaging line stopper, switching itself directly from a local DC24V signal without remote valve plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X350S-06B the Right Choice?
Size by comparing neighbour bores: the 40 mm bore offers 628 N push at 0.5 MPa versus 402 N here. Confirm the DC24V terminal entry and PT thread before ordering. Default action retracts the rod when energised; reposition the valve to extend-when-energised. Size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold a load. For the 350 mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF32X350S-06B FAQ
It generates 402 N push at 0.5 MPa and 643 N at 0.8 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) with a DC24V terminal coil. Size force within the 0.15-0.8 MPa valve operating window, as the assembled unit cannot run at the 1.0 MPa cylinder body rating.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This self-switching design removes the need for a separate remote valve, saving installation time and manifold slots.
