Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350S-06A is a genuine double-acting profile-type cylinder with a Ø50mm 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 SAUF50X350S-06A
The SAUF50X350S-06A 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 extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. The -S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
It delivers 982 N push and 825 N pull at 0.5 MPa. The 1/4" cylinder port and M16x1.5 rod thread are fixed by the 50 mm bore. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles 5 cycles/sec. Computed buyer insight: safe working load is roughly 589 N (60% of the 0.5 MPa push), and vertical lift capacity is about 50 kg with a 2:1 margin. Size within the 0.15-0.8 MPa valve range.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X350S-06A Is Used
Diverter Gate Actuation
Uses the integrated valve to switch a sorting flap directly at the conveyor lane without routing air lines back to a central manifold.
Decentralized Pallet Stop
Raises and lowers a pallet stop independently on a packaging line, saving manifold slots and simplifying installation.
Independent Clamp Station
Clamps parts at a standalone machining cell using one AC220V signal, eliminating the need for remote valve plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X350S-06A the Right Choice?
Size by comparing neighboring bores: a 40 mm bore gives 628 N push while a 63 mm bore gives 1559 N at 0.5 MPa. This 50 mm bore yields 982 N push and 825 N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT thread suit your supply. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Because the 4M210 valve limits operation to 0.15-0.8 MPa, never size the assembled unit at 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 loads. 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 SAUF50X350S-06A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) with an AC220V terminal coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating 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; it is not a load lock. For load holding on air loss, install an external rod lock or pilot-operated check valve.
