Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 150mm 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 SAUF63X150S-08B
The SAUF63X150S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310 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 makes it shorter than an ISO 15552 cylinder of the same bore. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
Operating in the 0.15-0.8 MPa valve window, it delivers a 1559 N push at 0.5 MPa. The 4M310-08 valve has a 1/4" port with a Cv of 1.4 and cycles up to 4 times per second. The bore sets the 3/8" cylinder port and M16x1.5 rod thread. For sizing, the safe working load is roughly 935 N, and vertical lift is about 79 kg 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 SAUF63X150S-08B Is Used
Decentralized Clamping
Ideal for large machining cells where each clamping station uses one coil signal, saving tubing runs back to a central manifold.
Inline Divert Gates
Perfect for diverting packages on a conveyor line, as the integrated valve allows localized control without extra plumbing.
Vertical Lift Stops
Suitable for material lift stops in automated storage systems, providing reliable actuation with a compact profile.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X150S-08B the Right Choice?
Size force between the 50 mm bore (push 982 N) and 80 mm bore (push 2513 N) at 0.5 MPa. This 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. Always size within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Confirm the DC24V terminal entry and PT threads. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Since the 150 mm stroke is below 300 mm, side-load guides are less critical. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load safely.
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 SAUF63X150S-08B FAQ
It delivers a 1559 N push and 1402 N pull at 0.5 MPa, using a built-in 4M310-08 valve with a 1/4" port and Cv 1.4. The DC24V coil operates at 3.0 W with IP65 protection. You must size the force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa.
By default the rod retracts when energised, but you can reconfigure it to extend by repositioning the valve. The 5/2 valve only routes air; it does not lock the piston. If air is lost, the load drifts, so add an external rod lock or pilot-operated check valve for load holding.
