Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800S-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 800mm 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 SAUF63X800S-08A
The SAUF63X800S-08A is an extruded aluminum profile-type double-acting 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 63mm bore delivers 1559N push and 1402N pull at 0.5MPa, operating safely within the valve's 0.15-0.8MPa window. The cylinder body rates to 1.0MPa but the assembled unit is capped by the valve limit. It includes a piston magnet for switches.
The integrated 4M310-08 valve has a 1/4-inch port, 25mm2 flow (Cv 1.4), and cycles up to 4 times per second. The AC220V terminal-entry coil is IP65 rated with a 0.05s response. The bore uses a 3/8-inch cylinder port, M16x1.5 rod thread, and Ø8xØ5 PU tube. Computed buyer insight: safe working load is roughly 935N (about 60% of the 1559N push at 0.5MPa), yielding a vertical lift capacity of approximately 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 SAUF63X800S-08A Is Used
Sorting Diverter
Decentralized package sorting where one coil signal per actuator pushes diverters without routing long tubing back to a central manifold.
Vertical Lift Gate
Lifting a 79kg access gate using the 800mm stroke, relying on the integrated 4M310 valve to save installation space on the frame.
Long-Stroke Pusher
Transferring parts along a machine bed where the built-in valve eliminates a remote valve island and the magnet allows position confirmation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X800S-08A the Right Choice?
Size by checking both neighboring bores: the 50mm bore yields 982N push at 0.5MPa, while the 80mm bore yields 2513N. This 63mm unit provides 1559N push at 0.5MPa. Confirm your coil is AC220V with terminal entry before ordering. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energized by repositioning the valve. Always size force within the 0.15-0.8MPa valve operating range, never the 1.0MPa cylinder body rating. The built-in valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. Because the 800mm stroke exceeds 300mm, use external guides to prevent rod bending and side-load damage.
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 SAUF63X800S-08A FAQ
It pushes 1559N and pulls 1402N at 0.5MPa. The built-in valve is a 4M310-08 (1/4-inch port, Cv 1.4, max 4 cycles/s) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window. The cylinder port is 3/8-inch.
Yes. The default action retracts the rod when energized, but you can reconfigure it to extend-when-energized simply by repositioning the valve on the cap. This self-switching design means no remote valve is needed, saving tubing and a manifold slot.
