Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-08B 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 SAUF63X900-08B
The SAUF63X900-08B 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 is shorter than an ISO 15552 unit of the same bore. This 63mm bore uses a 3/8" cylinder port, a Ø20mm rod, and M16x1.5 rod-end thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers 1559N push at 0.5MPa. The 4M310-08 valve has a 1/4" port, Cv 1.4, and runs up to 4 cycles/sec. The DC24V coil offers IP65 protection with terminal entry. Computed buyer insight: safe working load is roughly 935N (60% of the 0.5MPa push), suiting vertical lifts around 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 SAUF63X900-08B Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate on a long conveyor line. The integrated 4M310 valve switches the 900mm stroke locally, eliminating long tube runs back to a central manifold.
Remote Machine Guard Gate
Ideal for opening large safety guards on machine perimeters. One DC24V signal drives the 63mm bore, saving manifold space while providing 1559N push at 0.5MPa.
Vertical Material Lift
Raises pallets or totes in automated storage. The 935N safe working load handles vertical lifts up to 79kg with a 2:1 margin, operating safely within the 0.15-0.8MPa valve limit.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-08B the Right Choice?
Size by checking both neighbors: a 50mm bore gives 982N push at 0.5MPa, while an 80mm bore yields 2513N. This 63mm unit provides 1559N push and 1402N pull at 0.5MPa. Confirm the DC24V coil and terminal entry suit your control system. Remember the cylinder body rates to 1.0MPa, but the assembled SAUF operates strictly at 0.15-0.8MPa. The rod retracts when energized by default, but repositioning the valve changes it to extend-when-energized. Without air, the valve only routes flow and the piston drifts; add an external rod lock or pilot-operated check valve to hold loads. For the 900mm stroke, use external guides to prevent rod bending and side-load wear. This SKU lacks a magnet (-S), so it cannot accept magnetic switches.
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 SAUF63X900-08B FAQ
It pushes 1559N and pulls 1402N at 0.5MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, max 4 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit operates strictly within 0.15-0.8MPa.
No. The built-in valve routes air but is not a lock. If air is lost, the piston drifts and the 21mm cushions only decelerate near stroke ends. For load holding, install an external rod lock or pilot-operated check valve. The default action retracts when energized, but you can reposition the valve to extend on signal.
