Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-10A 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 SAUF63X900-10A
The SAUF63X900-10A 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" air port, a Ø20mm rod with an M16x1.5 thread, and 21mm adjustable cushions.
Operating within the 0.15-0.8 MPa valve window, it delivers a 1559N push force at 0.5MPa. The 4M310-10 valve provides 30mm2 flow (Cv 1.68) at up to 4 cycles/sec. The AC220V terminal entry coil is IP65 rated. Based on the 0.5MPa push force, the safe working load is roughly 935N, allowing a vertical lift of about 79kg with a 2:1 margin. Note this 900mm stroke exceeds 300mm, requiring external guide support to prevent rod bending.

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 SAUF63X900-10A Is Used
Long-stroke diverter
Decentralized 900mm stroke pushes diverter arms across wide conveyor belts without routing long tubing runs to a central manifold.
Vertical lift gate
Uses the one-signal 4M310 valve to raise and lower material handling gates, saving a manifold slot while providing 1559N push at 0.5MPa.
Machine guard door
Ideal for opening large equipment access doors where a local AC220V coil signal simplifies wiring and eliminates remote valve plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X900-10A the Right Choice?
When sizing, compare neighbouring bores: the 50mm bore pushes 982N while the 80mm bore pushes 2513N at 0.5MPa. This 63mm unit provides 1559N push and 1402N pull at 0.5MPa. Always size force within the 0.15-0.8 MPa valve operating range, never the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry coil meets your supply. The default action retracts the rod when energised; repositioning the valve switches it to extend-when-energised. Because this 900mm stroke exceeds 300mm, add external guides to handle side loads and prevent rod bending. The built-in valve routes air and is not a lock; the piston drifts on air loss and cushions only decelerate near stroke end. For a held load, add an external rod lock or pilot-operated check valve. This SKU lacks a magnet (-S) and cannot take a magnetic switch.
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 SAUF63X900-10A FAQ
It pushes 1559N and pulls 1402N at 0.5MPa, reaching 2494N at 0.8MPa. The built-in 4M310-10 valve has a 3/8" port, Cv 1.68, and runs at 4 cycles/sec. The AC220V terminal coil is IP65. Size force within the 0.15-0.8 MPa valve window, not the 1.0MPa cylinder body rating.
No, the built-in valve routes air and is not a load lock; the piston drifts on air loss. Add an external rod lock or pilot-operated check valve to hold a load. The rod retracts by default when the coil is energised, but you can reposition the valve to extend-when-energised.
