Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 80mm 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 SAUF63X80S-08B
The SAUF63X80S-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. The bore sets the 3/8" cylinder port and M16x1.5 rod thread, while the valve features a 1/4" port with a Cv of 1.4.
Operating on DC24V with terminal entry, the coil is IP65 rated and switches at 0.05s or less, supporting up to 4 cycles per second. The cylinder body rates to 1.0 MPa, but the integrated valve restricts the assembled working pressure to 0.15-0.8 MPa. At 0.5 MPa it delivers 1559N push force, giving a computed safe working load of roughly 935N or a 79kg vertical lift with a 2:1 margin. The S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF63X80S-08B Is Used
Decentralized Clamping Station
Eliminates valve manifold plumbing by switching the clamp directly from the cap-mounted 4M valve.
Independent Divert Gate
One coil signal drives the 80mm stroke gate, saving manifold slots across long conveyor lines.
Compact Lifting Stopper
Profile barrel saves machine space while delivering 1559N push force for parcel lifting stops.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80S-08B the Right Choice?
Size by comparing the 63mm bore (1559N push at 0.5 MPa) against the 50mm (982N) and 80mm (2513N) neighbours. Confirm the DC24V terminal entry and 1/4" valve port match your supply. Size force strictly within the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder rating. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve for held loads. The 80mm stroke exceeds the 75mm minimum, so no side-load guide is required.
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 SAUF63X80S-08B FAQ
It pushes 1559N and pulls 1402N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/s) running on DC24V. The cylinder body rates to 1.0 MPa, but you must size force within the assembled valve's 0.15-0.8 MPa working window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve on the cap. The valve only routes air; it does not lock the load, so use an external rod lock for holding.
