Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 300mm 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 SAUF50X300-08A
The SAUF50X300-08A 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 has a 1/4 inch cylinder port and an M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it pushes 982 N at 0.5 MPa. The AC220V terminal entry coil offers IP65 protection and responds in 0.05 s or less. The 4M210-08 valve flows 16 mm2 (Cv 0.89) at up to 5 cycles per second. Based on the 0.5 MPa push force, the safe working load is about 589 N, and it can vertically lift roughly 50 kg 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 SAUF50X300-08A Is Used
Inline Divert Gate
Decentralized diverter on a conveyor driven by one AC220V signal, saving manifold space and tubing runs back to a central control panel.
Zone Pusher Actuator
Independent package pusher in a storage system using the built-in 4M210 valve for fast local switching without extra remote plumbing.
Component Clamp Station
Single-station clamping on a large machine bed, actuated directly at the cap valve to simplify assembly and reduce installation time.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300-08A the Right Choice?
Size by checking both neighboring bores: the 40 mm bore pushes 628 N while the 63 mm bore pushes 1559 N at 0.5 MPa. This 50 mm bore gives 982 N push and 825 N pull at 0.5 MPa. Always size force within the 0.15-0.8 MPa assembled valve range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry coil meets your supply. The rod retracts when energized by default, but you can reposition the valve to extend on signal. This SKU lacks the S suffix for a magnet, so it cannot take a magnetic switch. For the 300 mm stroke, use an external guide to prevent rod bending and side-load wear. The valve routes air and is not a lock; to hold a load on air loss, add an external rod lock or pilot-operated check valve.
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 SAUF50X300-08A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4 inch port, Cv 0.89, 5/2 solenoid) running on AC220V. You must size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
Yes, the default action retracts the rod on signal, but you can reposition the valve to make it extend when energised. The valve only routes air; it is not a load lock. If you need to hold a load on air loss, install an external rod lock or pilot-operated check valve.
