Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80S-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 80mm 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 SAUF63X80S-08A
The SAUF63X80S-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 63mm bore delivers 1559N push and 1402N pull at 0.5MPa. The cylinder body rates to 1.0MPa, but you must size force within the integrated valve's 0.15-0.8MPa operating window. The 3/8" cylinder port and M16x1.5 rod thread handle robust decentralized tasks.
This model includes a piston magnet for CMSG/DMSG/EMSG switches. The 4M310-08 valve port is 1/4" with a Cv of 1.4, cycling up to 4 times per second. It uses an AC220V terminal entry coil rated IP65. Based on the 0.5MPa push force, the computed safe working load is roughly 935N, translating to a vertical lift capacity of about 79kg 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 SAUF63X80S-08A Is Used
Diverter Gate Actuation
Decentralized sorting line diverter where the integrated valve eliminates long tube runs back to a central manifold, enabling rapid 4 cycle/s switching.
Package Stopper Arm
Independent stopper arm on a packaging conveyor. The built-in 4M310-08 valve routes air directly at the cap, saving manifold space and simplifying maintenance.
Clamp Station Control
Single-station clamping mechanism on a large machine bed. One AC220V coil signal drives the 1559N clamping force without extra remote plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X80S-08A the Right Choice?
When sizing, compare neighbouring bores: the 50mm bore offers 982N push while the 80mm bore provides 2513N at 0.5MPa. This 63mm bore yields 1559N push, so verify your load stays near the 935N safe working threshold. Confirm the AC220V terminal entry and PT thread match your control system. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. Because the valve routes air, it is not a load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 80mm stroke, side-load guides are not strictly required, but always guide longer strokes exceeding 300mm.
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 SAUF63X80S-08A FAQ
It pushes 1559N and pulls 1402N at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) running on AC220V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within the valve's 0.15-0.8MPa window.
Yes. The default factory setting retracts the rod when energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve. This allows flexible machine sequencing without changing your wiring.
