Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 700mm 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 SAUF63X700-08A
The SAUF63X700-08A 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. This 63mm bore uses a 3/8" cylinder port, a Ø20mm rod with M16x1.5 thread, and 21mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers 1559N push force at 0.5 MPa. A practical safe working load is roughly 935N, capable of a 79kg vertical lift with a 2:1 margin. The 1/4" valve port yields a Cv of 1.4 and cycles up to 4 times per second. This AC220V terminal-entry coil is IP65 rated. Without the -S suffix, this SKU cannot take a magnetic switch.

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 SAUF63X700-08A Is Used
Divert Gate Actuation
Decentralized diverters on packaging lines benefit from one coil signal per gate, eliminating long tubing runs back to a central manifold.
Vertical Material Lift
Lifts loads up to 79kg with a 2:1 safety margin at 0.5MPa, using the integrated 4M310 valve to save installation space.
Machine Tool Loading
Pushes parts into machining centers with 1559N force, where the compact profile cylinder and self-contained switching simplify cell design.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700-08A the Right Choice?
Size by comparing both neighboring bores: the 50mm bore offers 982N push at 0.5MPa, while the 80mm bore provides 2513N. This 63mm unit delivers 1559N push and 1402N pull at 0.5MPa. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry matches your supply. The rod retracts when energized; reposition the valve to extend instead. For the 700mm stroke, use external guides to prevent rod bending and side-load wear. The built-in valve routes air but is not a lock; add an external rod lock or pilot-operated check valve to hold loads securely.
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 SAUF63X700-08A FAQ
It generates 1559N push and 1402N pull at 0.5MPa. The built-in valve is a 4M310-08 5/2 solenoid with a 1/4" port, Cv 1.4, and a 4 cycle/sec limit. The coil is AC220V with terminal entry. Size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
No, the built-in valve routes air and is not a load lock; the piston drifts on air loss. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil is energized, but you can reposition the valve to extend when energized.
