Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700-08B 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 SAUF63X700-08B
The AirTAC SAUF63X700-08B is a double-acting profile cylinder with a built-in 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. It uses a 3/8" cylinder port and an M16x1.5 rod thread.
Operating within the 0.15-0.8 MPa valve window, it delivers 1559 N push force at 0.5 MPa. The integrated 4M310-08 valve has a 1/4" port, Cv 1.4, and handles 4 cycles/sec. The DC24V terminal coil is IP65 rated. Based on the 0.5 MPa push figure, the safe working load is roughly 935 N, allowing a vertical lift of about 79 kg with a 2:1 margin. This SKU lacks a magnet, so it cannot accept 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 SAUF63X700-08B Is Used
Divert Gate Actuation
Drives a decentralized lane diverter directly at the conveyor, switching itself with one DC24V signal without routing long tube runs back to a central manifold.
Packaging Pusher
Pushes cartons on a packing line using the 1559 N thrust at 0.5 MPa, saving manifold space while the 4M310 valve handles 4 cycles per second.
Machine Guard Index
Moves a 700mm guard or access door on a large machine, relying on the compact profile cylinder and integrated valve to simplify installation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700-08B the Right Choice?
Size by checking both neighboring bores: the 50mm bore yields 982 N push at 0.5 MPa, while the 80mm bore yields 2513 N. This 63mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT threads suit your control panel. Size all force calculations within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The rod retracts when the coil is energized but can be reconfigured to extend by repositioning the valve. Since the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For the 700mm 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 SAUF63X700-08B FAQ
It delivers 1559 N push and 1402 N pull at 0.5 MPa, reaching 2494 N push at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4) with a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
No, the built-in valve only routes air and is not a lock; the piston drifts on air loss, so add an external rod lock or pilot-operated check valve to hold a load. Additionally, this specific SKU lacks a magnet and cannot accept a magnetic switch.
