Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-10B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-10B is a genuine double-acting profile-type cylinder with a Ø63mm bore, 900mm stroke and a built-in 4M310-10 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 SAUF63X900-10B
The SAUF63X900-10B 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 is shorter than an ISO 15552 cylinder of the same bore. It uses a Ø20 mm rod with an M16x1.5 thread, a 3/8" cylinder port, and 21 mm adjustable cushions.
Operating within the valve's 0.15-0.8 MPa window, it delivers a 1559 N push force at 0.5 MPa. The 3/8" valve port yields a 30 mm2 flow (Cv 1.68) with a max frequency of 4 cycles/s. The DC24V coil offers IP65 protection with a terminal entry. Based on the 0.5 MPa push force, the computed safe working load is roughly 935 N, translating to a vertical lift capacity of about 79 kg with a 2:1 margin. This 900 mm stroke 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 SAUF63X900-10B Is Used
Decentralized Conveyor Diverter
Mounts directly at the divert station to push packages without routing long tube runs back to a central manifold.
Independent Stacking Gate
Uses its self-contained 4M310 valve to operate a standalone pallet gate, saving a valve island slot in the main cabinet.
Remote Forming Press Ejector
Ejects parts at 4 cycles/s with a 935 N safe working load, driven by a single DC24V signal at the machine bed.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-10B the Right Choice?
Size force between the 50 mm bore (push 982 N) and 80 mm bore (push 2513 N) at 0.5 MPa. This 63 mm bore provides 1559 N push and 1402 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT threads match your control scheme. The cylinder body rates to 1.0 MPa, but you must size force within the built-in valve's 0.15-0.8 MPa operating window. The rod retracts when the coil is energised; reposition the valve to reverse this to extend-when-energised. The valve only routes air, so for load holding on air loss, add an external rod lock or pilot-operated check valve. At 900 mm stroke, 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 SAUF63X900-10B FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa, reaching 2494 N at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 30 mm2 flow) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly in a 0.15-0.8 MPa window.
No remote valve is needed; the integrated 4M 5/2 valve switches the actuator directly from one coil signal. The valve routes air but does not lock the piston, so the load will drift on air loss. Install an external pilot-operated check valve for vertical holding.
