Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 200mm 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 SAUF50X200S-08A
The SAUF50X200S-08A is a double-acting profile-type cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 50mm bore, 200mm stroke, 1/4" cylinder port, and an M16x1.5 rod thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982N push force at 0.5 MPa. The integrated valve provides 16mm2 flow (Cv 0.89) and handles up to 5 cycles/sec. The AC220V terminal entry coil is IP65 rated. With the -S suffix, a piston magnet is present for CMSG/DMSG/EMSG switches. For sizing, the safe working load is roughly 589N, allowing a vertical lift of 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 SAUF50X200S-08A Is Used
Decentralized Clamping
Ideal for independent clamping stations on a large machining line where running individual air lines back to a central manifold is impractical.
Inline Diverters
Powers sorting gates directly at the conveyor edge, using the integrated valve to switch rapidly without extra tubing to a remote bank.
Package Stops
Controls localized package stops on accumulation conveyors, saving manifold space and simplifying installation across long logistics layouts.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X200S-08A the Right Choice?
Size against the 0.5 MPa figures: this 50mm bore pushes 982N, sitting between the 40mm (628N) and 63mm (1559N) options. Confirm the AC220V terminal entry coil matches your supply. 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 lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 200mm stroke, ensure adequate side-load guidance.
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 SAUF50X200S-08A FAQ
It delivers 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) with an AC220V terminal coil. You must size force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
Yes. The default factory setting retracts the rod when energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This self-switching design means no remote valve is needed.
