Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-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 SAUF32X400S-08A
The SAUF32X400S-08A is a double-acting profile cylinder with a built-in 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 is shorter than an ISO 15552 cylinder of the same bore. This 32mm bore version features a 1/8" cylinder port, an M10x1.25 rod thread, and a 400mm stroke.
Operating within the 0.15-0.8 MPa valve window, it delivers 402N push force at 0.5MPa. The integrated valve offers 1/4" porting, Cv 0.89 flow, and 5 cycles/sec. The AC220V terminal entry coil is IP65 rated. With the -S suffix, a piston magnet enables CMSG/DMSG/EMSG switch mounting. Computed buyer insight: safe working load is roughly 241N, allowing a 20kg vertical lift 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 SAUF32X400S-08A Is Used
Modular Gating
Decentralized diverter gates on a packaging line use this self-switching cylinder to save manifold space and simplify tubing.
Inline Sorting
Independent pusher arms on a conveyor rely on the built-in 4M210 valve for rapid 5 cycles/sec sorting without remote valves.
Machine Clamping
Distributed clamping stations utilize the one-signal operation, reducing installation time across large automated machinery.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X400S-08A the Right Choice?
Size by comparing neighboring bores: the 32mm bore yields 402N push at 0.5MPa, whereas a 40mm bore provides 628N. Confirm the AC220V voltage and terminal entry match your control system. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 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 SAUF32X400S-08A FAQ
It delivers 402N push and 345N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) with an AC220V terminal coil. The cylinder body rates to 1.0MPa, but you must size force within the assembled valve's 0.15-0.8MPa operating window.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend on signal by repositioning the integrated valve. Because the valve only routes air, it cannot hold a load without air pressure; use an external rod lock for fail-safe holding.
