Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000S-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 1000mm 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 SAUF50X1000S-08B
The SAUF50X1000S-08B is a double-acting profile cylinder with a built-in AirTAC 4M210-08 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 unit of the same bore.
It carries a 50mm bore, a 1/4" cylinder port, and a 1/4" valve port with a 16mm2 flow (Cv 0.89). The DC24V coil offers IP65 protection and switches up to 5 cycles/sec. Size force within the 0.15-0.8 MPa valve window; at 0.5 MPa it pushes 982N and pulls 825N. This yields a safe working load around 589N, or a 50kg vertical lift with a 2:1 margin. The -S suffix provides a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF50X1000S-08B Is Used
Long-Stroke Diversion
Pushes packages across a wide conveyor belt using a single DC24V signal without a central manifold.
High-Bay Ejection
Ejects totes from tall racking where running long remote airlines is impractical.
Decentralised Press
Provides 982N clamping force at independent stations, freeing up valve island slots.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X1000S-08B the Right Choice?
Size between the 40mm bore (628N push @0.5MPa) and 63mm bore (1559N push @0.5MPa). This 50mm bore delivers 982N push at 0.5MPa. Confirm the DC24V terminal entry and PT threads. The cylinder body rates to 1.0MPa but the integrated valve limits operation to 0.15-0.8MPa. The rod retracts when energised; reposition the valve to extend on signal. The valve routes air and does not lock the load—add an external rod lock or pilot-operated check valve for holding. At 1000mm stroke, use external guides to prevent rod bending and side loads.
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 SAUF50X1000S-08B FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) on a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit operates at 0.15-0.8MPa.
By default the rod retracts when energised. You can reconfigure it to extend-when-energised by repositioning the valve. The valve only routes air, so add an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
