Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 100mm 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 SAUF50X100S-08A
The SAUF50X100S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One AC220V 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. The -S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.
Operating strictly within the 0.15-0.8 MPa valve window, it delivers 982 N push and 825 N pull at 0.5 MPa. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) and handles up to 5 cycles per second. The cylinder bore port is 1/4" with a PT thread. For sizing, the safe working load is roughly 589 N, and vertical lift capacity is about 50 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 (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 SAUF50X100S-08A Is Used
Diverter Gate Actuation
Drives a localized sorting flap directly at the conveyor edge using one AC220V signal, removing the need to route tubing back to a central manifold.
Independent Clamping Station
Provides self-contained clamping on a multi-station fixture, where the built-in 4M210-08 valve allows each clamp to cycle independently without a remote valve bank.
Decentralized Flap Folder
Folds carton flaps on a moving line, leveraging the compact profile and integrated magnet for precise position confirmation at each machine lane.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X100S-08A the Right Choice?
Size force between the 40 mm bore (628 N push) and 63 mm bore (1559 N push) options at 0.5 MPa. This 50 mm bore provides 982 N push, so verify your load stays under the 589 N safe working threshold. Confirm the AC220V terminal entry meets your control voltage. The rod retracts when energised by default, but you can reposition the valve to extend on signal. Always size pressure within the 0.15-0.8 MPa valve range, 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 loads safely. For this 100 mm stroke, side-load is minimal, but ensure adequate guidance for longer strokes.
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 SAUF50X100S-08A FAQ
It generates 982 N push and 825 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 coil. Although the cylinder body rates to 1.0 MPa, you must size the assembled unit within the 0.15-0.8 MPa valve operating window.
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. Because the valve only routes air, it will not hold the load on air loss—you need an external rod lock for that.
