Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 450mm 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 SAUF50X450S-08B
The SAUF50X450S-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 makes it shorter than an ISO 15552 cylinder of the same bore. The bore sets the 1/4" cylinder port and M16x1.5 rod thread, while the valve features a 1/4" port, 16 mm2 flow (Cv 0.89), and 5 cycles/s max.
This DC24V terminal-entry coil (IP65) operates within the 0.15-0.8 MPa valve window, delivering 982 N push at 0.5 MPa. The computed safe working load is 589 N, allowing a vertical lift of roughly 50 kg with a 2:1 margin. The -S suffix provides a piston magnet for CMSG/DMSG/EMSG sensors. The valve routes air but does not lock the load.

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 SAUF50X450S-08B Is Used
Decentralized Forming Press
Ideal for a large press where each actuator switches itself via one DC24V signal, removing long tubing runs back to a central manifold.
Inline Divert Gate
Perfect for a 450 mm divert stroke on a conveyor, using the integrated 4M210 valve to save manifold space while handling a 50 kg vertical lift.
Independent Lift Station
Suits a standalone pallet lift in a large facility, leveraging the built-in magnet and valve for local control without extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-08B the Right Choice?
Size force between 0.15-0.8 MPa: this 50 mm bore yields 982 N push at 0.5 MPa, sitting between the 40 mm (628 N) and 63 mm (1559 N) options. Confirm the DC24V terminal entry and PT threads match your supply. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The cylinder body rates to 1.0 MPa, but the assembled unit is strictly limited to the valve's 0.15-0.8 MPa range. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve for held loads. For the 450 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 SAUF50X450S-08B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s) with a DC24V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it is not a load lock, so the piston will drift on air loss. Add an external rod lock or pilot-operated check valve to hold a load.
