Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 125mm 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 SAUF63X125-08B
The SAUF63X125-08B 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 unit of the same bore. This 63mm bore uses a 3/8" air port and a 1/4" valve port.
It delivers 1559N push and 1402N pull at 0.5MPa. The safe working load is roughly 935N, allowing a 79kg vertical lift with a 2:1 margin. The integrated valve flows 25mm2 (Cv 1.4) at up to 4 cycles/s. The DC24V coil offers IP65 protection with terminal entry. Size within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating.

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 SAUF63X125-08B Is Used
Diverter Gate
Decentralized sorting line actuator switching itself via the built-in valve, cutting tubing runs to a central manifold.
Clamp Station
Independent machine clamping where the 4M310 valve handles 4 cycles/s directly at the work point without remote plumbing.
Package Stopper
Single-signal routing for a packaging line stop; the compact profile fits tight frames while delivering 1559N push force.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X125-08B the Right Choice?
When sizing, compare this 63mm bore (1559N push @0.5MPa) against the 50mm (982N) and 80mm (2513N) neighbors. The 125mm stroke is standard and above the 75mm SAUF minimum. Confirm the DC24V terminal entry and PT threads suit your control panel. The rod retracts when energized by default; reposition the valve to extend on signal. The assembly runs 0.15-0.8MPa because the valve limits the 1.0MPa cylinder body. This SKU lacks a magnet (-S), so it cannot take a magnetic switch. 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 125mm stroke, side-load is minimal, but always guide the rod.
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 SAUF63X125-08B FAQ
It pushes 1559N and pulls 1402N at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25mm2 flow, max 4 cycles/s). The DC24V coil uses terminal entry. The cylinder body rates to 1.0MPa, but you must size force within the assembled valve's 0.15-0.8MPa operating window.
By default the rod retracts when the coil is energized; you can reposition the valve to extend on signal. The valve only routes air, so it is not a load lock. Without air pressure the piston drifts, so add an external rod lock or pilot-operated check valve for holding.
