Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 500mm 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 SAUF50X500S-08B
The SAUF50X500S-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. It includes a piston magnet for CMSG/DMSG/EMSG switches.
This 50mm bore delivers 982N push and 825N pull at 0.5MPa. The integrated valve limits operation to 0.15-0.8MPa, even though the cylinder body rates to 1.0MPa. With a 1/4" valve port, flow is 16mm2 (Cv 0.89) at up to 5 cycles/sec. The bore dictates a 1/4" cylinder port with an M16x1.5 rod thread. Computed buyer insight: safe working load is roughly 589N (60% of the 0.5MPa push), and vertical lift is about 50kg 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 SAUF50X500S-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. One DC24V signal actuates the 500mm stroke without running long tubing back to a central manifold.
Independent Pack Pusher
Ideal for isolated push-off stations. The built-in 4M210 valve handles the 50kg vertical lift capacity locally, freeing up manifold slots.
Machine Guard Gate
Drives a 500mm access gate with CMSG switches for position feedback. The compact profile saves floor space compared to standard cylinders.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500S-08B the Right Choice?
Size both ways: this 50mm bore pushes 982N at 0.5MPa, sitting between the 40mm (628N) and 63mm (1559N) options. Confirm the DC24V terminal entry and PT threads. The coil retracts the rod by default; reposition the valve to extend-when-energised. Size force strictly within the 0.15-0.8MPa valve window. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve to hold loads. For the 500mm 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 SAUF50X500S-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) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled SAUF must operate within the valve's 0.15-0.8MPa window.
Yes, the default action retracts the rod on energisation, but you can reposition the valve to extend-when-energised. The valve only routes air; it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve for holding.
