Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-08B 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 SAUF32X400-08B
The SAUF32X400-08B 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 32mm bore delivers 402N push and 345N pull at 0.5MPa, operating within the 0.15-0.8MPa valve window. The cylinder body rates to 1.0MPa but the integrated valve limits the assembled unit to 0.8MPa.
This model features a 1/4" valve port with 16mm2 flow (Cv 0.89) and a 1/8" cylinder port. The DC24V terminal entry coil offers IP65 protection and allows up to 5 cycles per second. For sizing, the safe working load is roughly 241N (60% of the 402N push force), translating to a vertical lift capacity of about 20kg 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 SAUF32X400-08B Is Used
Decentralized Clamping
Ideal for remote clamping stations where running individual lines to a central manifold is impractical, switching directly from one local signal.
Sorting Diverter
Perfect for space-constrained conveyor diverters, saving manifold space and reducing tubing complexity across long machine frames.
Package Pusher
Suits independent package push-off mechanisms that require standalone operation without dedicating a valve island slot.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400-08B the Right Choice?
When sizing, compare this 32mm bore (402N push at 0.5MPa) against the 40mm bore (628N) to ensure adequate force. Verify the DC24V terminal coil and PT thread meet your electrical specs. Default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8MPa valve range. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For the 400mm 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 SAUF32X400-08B FAQ
It generates 402N push and 345N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) with a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within 0.15-0.8MPa.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend on signal. The valve only routes air; it is not a load lock, so the piston will drift on air loss. Use an external rod lock or pilot-operated check valve for load holding.
