Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X500S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X500S-08B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 500mm 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 SAUF63X500S-08B
The SAUF63X500S-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 is shorter than an ISO 15552 unit of the same bore. This 63mm bore delivers 1559N push and 1402N pull at 0.5MPa. The cylinder port is 3/8" and the rod thread is M16x1.5.
The integrated valve has a 1/4" port, 25mm2 flow (Cv 1.4), and cycles up to 4 times per second. The DC24V terminal coil offers IP65 protection. The cylinder body rates to 1.0MPa, but the valve limits operation to 0.15-0.8MPa. Based on the 0.5MPa push force, the safe working load is roughly 935N, allowing a vertical lift of about 79kg with a 2:1 margin. The S suffix indicates a piston magnet for CMSG/DMSG/EMSG switches.

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 SAUF63X500S-08B Is Used
Decentralized Conveyor Divert
Mounts directly on a diverter arm. One DC24V signal actuates the 500mm stroke without routing long tubes back to a central manifold.
Machine Tool Guard Gate
Operates a large safety door. The integrated 4M310 valve simplifies wiring and the piston magnet supports position confirmation.
Vertical Package Stopper
Lifts items up to 79kg safely. The self-contained valve removes manifold clutter while providing 1559N push force at 0.5MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X500S-08B the Right Choice?
Size this 63mm bore against the neighbouring 50mm (982N push) and 80mm (2513N push) options at 0.5MPa. Confirm the DC24V terminal entry and PT threads meet your control specs. The rod retracts when the coil energises, but you can reconfigure it to extend-when-energised by repositioning the valve. Always size force within the 0.15-0.8MPa valve window, never the 1.0MPa cylinder rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For the 500mm stroke, use external guides to prevent rod bending and side-load 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 SAUF63X500S-08B FAQ
It delivers 1559N push and 1402N pull at 0.5MPa, reaching 2494N push at 0.8MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4M310 family) with a DC24V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the 0.15-0.8MPa valve window.
By default the rod retracts when the coil is energised. You can change it to extend-when-energised by repositioning the integrated valve. Because the valve only routes air, it cannot hold a load without air pressure; use an external rod lock for suspended loads.
