Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450S-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 450mm 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 SAUF63X450S-08A
The SAUF63X450S-08A 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 dictates a 3/8" cylinder port and an M16x1.5 rod thread, while the valve features a 1/4" port. A piston magnet is included for CMSG/DMSG/EMSG switches.
Operating on AC220V (terminal entry, IP65), the integrated valve flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. Size force within the 0.15-0.8 MPa valve window, where it delivers 1559 N push at 0.5 MPa. This yields a safe working load of roughly 935 N, or a 79 kg vertical lift with a 2:1 margin. The cylinder body rates to 1.0 MPa, but the assembled unit is capped by the 0.8 MPa valve limit.

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 SAUF63X450S-08A Is Used
Package Divert Gate
Decentralized diverter on a sorting line where one coil signal per actuator removes the need for a central valve manifold.
Vertical Lift Station
Lifting pallets up to 79 kg with a 2:1 safety margin, using the built-in magnet for position feedback.
Machine Guard Gate
Driving a 450 mm access gate directly from the cylinder cap valve, slashing tubing runs across the machine frame.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X450S-08A the Right Choice?
When sizing, compare neighboring bores: the 50 mm bore offers 982 N push at 0.5 MPa, while the 80 mm bore provides 2513 N. This 63 mm bore gives 1559 N push and 1402 N pull at 0.5 MPa. Confirm the AC220V coil and terminal entry meet your control requirements. The rod retracts by default when energized, but you can reconfigure it to extend by repositioning the valve. Always size within the 0.15-0.8 MPa valve operating range. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 450 mm 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 SAUF63X450S-08A FAQ
It delivers 1559 N push and 1402 N pull at 0.5 MPa, peaking at 2494 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s max) running on AC220V. Although the cylinder body rates to 1.0 MPa, size force within the assembled valve's 0.15-0.8 MPa operating window.
Yes, the default action retracts the rod when energized, but you can swap it to extend-when-energized simply by repositioning the valve. The 5/2 valve routes air and is not a lock; it cannot hold a load on air loss. Install an external rod lock or pilot-operated check valve for secure load holding.
