Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X200S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X200S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 200mm stroke and a built-in 4M310-08 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 SAUF63X200S-08B
The SAUF63X200S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 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 is shorter than an ISO 15552 cylinder of the same bore. This unit includes a piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve has a 1/4 inch port, Cv 1.4 flow, and runs at 4 cycles/sec. The cylinder bore features a 3/8 inch port, M16x1.5 rod thread, and 21 mm cushions. Operating pressure is 0.15-0.8 MPa because the valve limits the 1.0 MPa cylinder body. At 0.5 MPa it pushes 1559 N, giving a safe working load of roughly 935 N or a 79 kg vertical lift 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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 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 SAUF63X200S-08B Is Used
Diverter Gate Actuation
Drives a routing flap on a conveyor line directly from one coil signal, removing the need to trace tubing back to a central manifold.
Decentralized Pallet Stop
Raises and lowers a pallet stop in a packaging cell, using the integrated 4M310-08 valve to cut installation time.
Independent Clamp Station
Powers a clamping jaw on a multi-station machine without consuming a slot in the main valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X200S-08B the Right Choice?
Size force between the 0.15-0.8 MPa valve window; the 63mm bore pushes 1559 N at 0.5 MPa, sitting between the 50mm (982 N) and 80mm (2513 N) options. The DC24V terminal entry coil is IP65 rated. Default action retracts the rod when energised, but you can reposition the valve to extend on signal. The built-in valve routes air and is not a lock, so add an external rod lock or pilot-operated check valve to hold a load. For this 200mm stroke, guide the mechanism to manage side loads. The -S suffix enables sensor tracks.
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 SAUF63X200S-08B FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4 inch port, Cv 1.4, max 4 cycles/sec) running on a DC24V terminal coil. You must size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating.
Yes. The default action retracts the rod when energised, but you can reposition the built-in valve to make it extend on signal. Because the valve only routes air, use an external rod lock or pilot-operated check valve if you need to hold a load without air.
