Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 400mm stroke and a built-in 4M210-08 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 SAUF32X400-08A
The SAUF32X400-08A is a compact double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, 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 1/8" cylinder port, an M10x1.25 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve range, it delivers 402 N push force at 0.5 MPa. The integrated 4M210-08 valve has a 1/4" port, 16 mm2 flow (Cv 0.89), and cycles up to 5 times per second. The AC220V terminal entry coil is IP65 rated. Since this 400 mm stroke lacks a magnet suffix, it cannot accept a magnetic switch. For sizing, the safe working load is roughly 241 N, and vertical lift is about 20 kg with a 2:1 margin.

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 SAUF32X400-08A Is Used
Decentralized Clamping
Ideal for clamping stations on a large machine bed where running individual lines to a central manifold is impractical, switching directly from one AC220V signal.
Inline Divert Gate
Perfect for a 400 mm divert gate on a conveyor, saving tubing and manifold space by mounting the 4M210 valve directly on the cylinder cap.
Package Pusher
Suitable for pushing cartons between lanes, providing 402 N of push force at 0.5 MPa without needing a remote valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-08A the Right Choice?
When sizing, compare neighbouring bores: the 32 mm bore gives 402 N push at 0.5 MPa, while a 40 mm bore offers 628 N. This model uses an AC220V terminal entry coil; verify your voltage and entry needs before ordering. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold a load. For this 400 mm stroke, use an external guide to prevent rod bending and side-load damage. Mounting accessories are compatible with the AirTAC SC series.
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 SAUF32X400-08A FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec max) driven by an AC220V terminal entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
Yes, the default action retracts the rod on signal, but you can reconfigure it to extend by repositioning the valve. The valve only routes air and is not a lock; the piston will drift on air loss. Add an external rod lock or pilot-operated check valve for load holding.
