Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700S-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 SAUF63X700S-08B
The SAUF63X700S-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 makes it shorter than an ISO 15552 cylinder of the same bore. The bore dictates a 3/8" cylinder port and an M16x1.5 rod thread.
Operating within the valve's 0.15-0.8 MPa window, it generates 1559 N push at 0.5 MPa. A practical computed insight sizes the safe working load at roughly 935 N, with a vertical lift capacity of about 79 kg at a 2:1 margin. The integrated valve provides 25 mm2 flow (Cv 1.4) at a 1/4" port, switching up to 4 cycles per second. The -S suffix adds a piston magnet for CMSG/DMSG/EMSG sensors.

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 SAUF63X700S-08B Is Used
Divert Gate Actuation
Drives a sorting diverter directly at the lane, using the built-in valve to switch locally without routing air lines back to a central manifold.
Vertical Package Lift
Lifts packages using the 79 kg vertical lift capacity, relying on the piston magnet for position confirmation at the top and bottom of the 700 mm travel.
Machine Guard Door
Opens and closes heavy access doors on large machinery, benefiting from the compact profile and self-contained 4M310 valve for fast decentralized cycling.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X700S-08B the Right Choice?
Size by checking both neighboring bores: the 50 mm bore yields 982 N push at 0.5 MPa, while the 80 mm bore yields 2513 N—this 63 mm bore sits comfortably between at 1559 N. Confirm the DC24V terminal entry and PT threads match your control panel. Default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always size force within the 0.15-0.8 MPa valve limit, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. At 700 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 SAUF63X700S-08B FAQ
It pushes 1559 N and pulls 1402 N 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, 25 mm2 flow) running on DC24V. You must size force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
By default the rod retracts when the coil receives a signal. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. This single-signal operation eliminates the need for a separate remote valve.
