Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X200-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X200-08B 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 SAUF63X200-08B
The AirTAC SAUF63X200-08B is a double-acting profile cylinder with a built-in 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. The 3/8" cylinder port and M16x1.5 rod thread handle robust tasks.
Operating within the 0.15-0.8 MPa valve window, it delivers a 1559 N push force at 0.5 MPa. The DC24V terminal coil offers IP65 protection and a 0.05 s response. With a 1.4 Cv flow and 4 cycles/s frequency, the safe working load is roughly 935 N, capable of a 79 kg vertical lift with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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 SAUF63X200-08B Is Used
Diverter Gate Control
Decentralized sorting line actuation where one coil signal per gate saves manifold space and simplifies tubing runs.
Machine Tool Clamping
Independent clamping stations on a large machining center benefit from the integrated 4M310-08 valve and 4 cycles/s speed.
Packaging Pusher
Profile cylinder pushers handling cartons use the 935 N safe working load effectively without needing remote valves.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X200-08B the Right Choice?
Size by comparing neighbouring bores: the 50 mm bore gives 982 N push at 0.5 MPa, while the 80 mm bore gives 2513 N. This 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT thread meet your control voltage. The default action retracts the rod when energised, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve limit, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 200 mm stroke, ensure side-load guidance to prevent rod 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 SAUF63X200-08B FAQ
It generates 1559 N push and 1402 N pull at 0.5 MPa, reaching 2494 N push at 0.8 MPa. The built-in valve is a 4M310-08 5/2 solenoid with 1/4" port, 1.4 Cv flow, and 4 cycles/s max. It uses a DC24V terminal coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the built-in valve. This allows flexible machine design without extra remote valves, though the valve only routes air and does not lock the load.
