Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 700mm 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 SAUF50X700-08B
The AirTAC SAUF50X700-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve on the cap. One DC24V 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 features a 1/4" cylinder port and a 1/4" valve port.
Operating within the valve's 0.15-0.8 MPa range, it delivers 982 N push force at 0.5 MPa. The valve flows 16 mm2 (Cv 0.89) at up to 5 cycles per second. For sizing, the safe working load is roughly 589 N, and it can vertically lift about 50 kg with a 2:1 margin. Because this SKU lacks the -S magnet suffix, it cannot accept a magnetic switch.

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 SAUF50X700-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert lane to actuate a guide. One coil signal per actuator removes the need to trace long tubing runs back to a central manifold.
Long-Stroke Package Pusher
Pushes cartons across a 700 mm roller transfer. The integrated 4M210 valve keeps response time under 0.05 seconds without remote delay.
Independent Machine Clamp
Clamps a workpiece at a remote station. The self-contained DC24V valve frees up manifold slots for other machine functions.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X700-08B the Right Choice?
When sizing, compare against the neighbouring 40 mm bore (628 N push @0.5 MPa) and 63 mm bore (1559 N push @0.5 MPa) to ensure the 50 mm bore fits your load. Confirm the DC24V terminal entry and PT threads meet your electrical and plumbing needs. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. Because the 700 mm stroke exceeds 300 mm, use an external guide to prevent rod bending and side-load wear. The built-in valve routes air but does not hold the load on pressure loss—add an external rod lock or pilot-operated check valve for suspension.
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 SAUF50X700-08B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with a 1/4" port, 16 mm2 flow (Cv 0.89), and a 5 cycle/s limit. The coil is DC24V (IP65). Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised; you can reposition the valve to make it extend-when-energised. The valve only routes air—it is not a lock. On air loss the piston drifts, so add an external rod lock or pilot-operated check valve if you need to hold a suspended load.
