Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-08A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 900mm 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 SAUF63X900-08A
The SAUF63X900-08A 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 valves and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 3/8" air port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers a 1559 N push force at 0.5 MPa. The 1/4" valve port flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. The AC220V terminal entry coil is IP65 rated. For sizing, the safe working load is roughly 935 N, and vertical lift capacity is 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 SAUF63X900-08A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. One AC220V signal actuates the 900mm stroke without running long tubing back to a central manifold.
Large Machine Guard Door
Opens a wide safety guard on heavy machinery. The built-in 4M310-08 valve handles the 63mm bore flow locally, simplifying the pneumatic layout.
Vertical Material Lift
Raises a 79kg payload in a storage system. The compact profile saves space, while the integrated valve ensures fast response without a remote valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-08A the Right Choice?
Size by checking both neighboring bores: the 50mm bore pushes 982 N and the 80mm bore pushes 2513 N at 0.5 MPa. This 63mm bore gives 1559 N push and 1402 N pull at 0.5 MPa. 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 coil meets your supply. The rod retracts when energized, but you can reposition the valve to extend on signal. Because the 900mm stroke exceeds 300mm, use an external guide to prevent rod bending and side loads. The valve only routes air; add an external rod lock or pilot-operated check valve to hold loads safely.
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 SAUF63X900-08A FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) running at max 4 cycles/s. The AC220V terminal coil is IP65. Size the force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body limit.
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 self-switching design removes the need for a separate remote valve.
