Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 300mm stroke and a built-in 4M210-06 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 SAUF50X300S-06A
The SAUF50X300S-06A is a double-acting profile-type cylinder with a built-in AirTAC 4M210-06 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 1/4" cylinder port and M16x1.5 rod thread handle robust tasks.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982 N push at 0.5 MPa. A computed buyer insight: safe working load is roughly 589 N, allowing a vertical lift of about 50 kg with a 2:1 margin. The 1/8" valve port yields a Cv of 0.78 and 5 cycles per second. This -S model includes a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF50X300S-06A Is Used
Decentralized Conveyor Divert
Mounts directly on the line for one-signal diverting. The built-in 4M210-06 valve eliminates long tube runs back to a central manifold.
Packaging Gate Control
Ideal for isolated packaging gates. The AC220V terminal coil switches locally at 5 cycles per second without a remote valve island.
Independent Clamp Station
Perfect for standalone clamping on a large machine. The 50 mm bore yields 982 N push while saving a manifold slot for simpler plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X300S-06A the Right Choice?
Size by comparing neighbors: the 40 mm bore gives 628 N push while the 63 mm bore gives 1559 N at 0.5 MPa. This 50 mm bore provides 982 N push and 825 N pull at 0.5 MPa. Confirm the AC220V terminal entry meets your control voltage. 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 range, not the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For this 300 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 SAUF50X300S-06A FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 with a 1/8" port, Cv 0.78, and 5 cycles/s. The coil is AC220V with terminal entry. Size 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 coil energisation, but you can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This allows flexible machine sequencing without extra remote valves.
