Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75-08B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 75mm 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 SAUF50X75-08B
The SAUF50X75-08B is a double-acting profile cylinder with a built-in AirTAC 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 is shorter than an ISO 15552 cylinder of the same bore. This 50mm bore uses a 1/4" air port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Size force strictly within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it delivers 982N push and 825N pull. This yields a safe working load of roughly 589N, or a 50kg vertical lift with a 2:1 margin. The valve provides 16mm2 flow (Cv 0.89) at up to 5 cycles per second. Because this SKU lacks the S suffix, it cannot take 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 SAUF50X75-08B Is Used
Diverter Gate Actuation
Decentralized sorting lines use this self-switching cylinder to push diverter gates directly at the conveyor, removing the need to run long tubing back to a central valve manifold.
Independent Clamping Stations
Multi-station machining fixtures benefit from the built-in 4M210 valve, allowing each clamping point to operate independently from a single coil signal without consuming manifold space.
Carton Flap Folding
Packaging lines deploy these compact profile cylinders to fold flaps on demand, leveraging the 5 cycles per second speed to keep pace with high-throughput wrapping machines.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75-08B the Right Choice?
When sizing, compare both ways: the 40mm bore neighbor offers 628N push at 0.5MPa, while the 63mm bore offers 1559N. This 50mm bore provides 982N push and 825N pull at 0.5MPa. Confirm the DC24V terminal entry and PT thread meet your control specs. The rod retracts by default when energized, but you can reconfigure it to extend by repositioning the valve. The 4M210 valve limits operation to 0.15-0.8 MPa. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold loads safely. For this 75mm stroke, side-load guides are minimal, but ensure adequate guidance for any stroke over 300mm.
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 SAUF50X75-08B FAQ
It generates 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on DC24V. Although the cylinder body rates to 1.0MPa, you must size force within the valve's 0.15-0.8MPa operating window.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend when energized simply by repositioning the built-in valve. This self-contained switching means no remote valve is needed, saving installation time.
