Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X160-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X160-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 160mm 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 SAUF63X160-08B
The SAUF63X160-08B 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 63mm bore pushes 1559N at 0.5MPa. The cylinder body rates to 1.0MPa, but the integrated valve limits operation to a 0.15-0.8MPa window.
This unit uses a DC24V terminal-entry coil (IP65, 3.0W) with PT threads. The 1/4" valve port gives 25mm2 flow (Cv 1.4) at up to 4 cycles/s. Based on the 0.5MPa push force, the safe working load is roughly 935N, translating to a vertical lift capacity of about 79kg with a 2:1 margin. The 3/8" cylinder port, Ø20mm rod, and 21mm cushions are fixed by the bore.

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 SAUF63X160-08B Is Used
Diverter Gate Actuation
Uses the integrated valve to switch a sorting flap directly at the conveyor lane without routing air lines back to a central manifold.
Decentralized Pallet Stop
Deploys a stop block on a roller bed using a single DC24V signal, cutting installation time and tubing in large facilities.
Independent Clamp Station
Holds a workpiece in a multi-station cell where each clamp fires individually via its built-in 4M310 valve.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X160-08B the Right Choice?
Size by checking both neighbours: the 50mm bore pushes 982N at 0.5MPa, while the 80mm bore reaches 2513N, so this 63mm bore at 1559N fits mid-range. Confirm the DC24V terminal entry and PT threads match your supply. Default action retracts the rod when energised, but you can reposition the valve to extend on signal. Size all forces within the 0.15-0.8MPa valve range, never the 1.0MPa cylinder rating. The valve only routes air; it is not a lock, so add an external rod lock or pilot-operated check valve to hold loads. For this 160mm stroke, guide the load to manage side-load. Because this SKU lacks the S suffix magnet, it cannot take a magnetic switch.
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 SAUF63X160-08B FAQ
It delivers 1559N push and 1402N pull at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25mm2 flow) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within 0.15-0.8MPa.
Yes. The default action retracts the rod when energised, but you can reconfigure it to extend on signal by repositioning the valve. This self-switching design removes the need for a remote valve.
