Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X225-10A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X225-10A is a genuine double-acting profile-type cylinder with a Ø63mm bore, 225mm 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 SAUF63X225-10A
The AirTAC SAUF63X225-10A is a double-acting profile cylinder with a built-in 4M310 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. It features a 63mm bore, 225mm stroke, and a 3/8" air port.
Operating within the 0.15-0.8 MPa valve window, it delivers 1559 N push force at 0.5 MPa. The safe working load is roughly 935 N, allowing a vertical lift of about 79 kg with a 2:1 margin. The integrated 4M310-10 valve has a 3/8" port, Cv 1.68 flow, and switches up to 4 cycles per second. This terminal-entry AC220V coil is IP65 rated, but without an S suffix, this SKU cannot take 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 SAUF63X225-10A Is Used
Decentralized Clamping
Ideal for large machining cells where mounting a local AC220V valve on each clamp avoids long tubing runs back to a central manifold.
Inline Diverters
Provides independent 4M310 valve control for sorting pushes on a conveyor, saving manifold slots while delivering 1559 N force at 0.5 MPa.
Vertical Lift Stops
Handles vertical stopping tasks safely, lifting roughly 79 kg with a 2:1 margin directly from the cap-mounted valve signal.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF63X225-10A the Right Choice?
Size by comparing neighbor bores: the 50mm bore offers 982 N push at 0.5 MPa, while the 80mm bore provides 2513 N. 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 your coil is AC220V with terminal entry. The rod retracts when energized, but you can reposition the valve to extend on signal. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For this 225mm stroke, ensure side-load guidance.
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 SAUF63X225-10A FAQ
It delivers 1559 N push and 1402 N pull at 0.5 MPa, and 2494 N push at 0.8 MPa. The built-in valve is a 4M310-10 (3/8" port, Cv 1.68, 4 cycles/sec max). The coil is AC220V with terminal entry. You must size force within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating.
The built-in valve only routes air; it is not a load lock, so the piston drifts on air loss. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when the coil is energized, but you can reposition the valve to make it extend on signal.
