Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 225mm 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 SAUF100X225S-08B
The SAUF100X225S-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 100mm bore version has a 1/2" cylinder port, an M20x1.5 rod thread, and a 225mm stroke.
The integrated valve features a 1/4" port with a Cv of 1.4 and cycles up to 4 times per second. It operates via a DC24V terminal entry coil rated IP65. Because the valve limits the assembly, size force within the 0.15-0.8 MPa window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 3927 N, yielding a safe working load of roughly 2356 N and a vertical lift capacity of about 200 kg with a 2:1 margin. The S suffix means a piston magnet is included for CMSG/DMSG/EMSG switches.

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 (Ø100mm)

| 0.7 MPa | 5498 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 SAUF100X225S-08B Is Used
Decentralized Press Clamps
Ideal for large stamping machines where running a single DC24V signal to each clamp saves manifold space and complex tubing.
Inline Diverters
Provides independent actuation for sorting gates without a central valve island, simplifying maintenance on long material handling lines.
Modular Assembly Stations
Delivers high push force up to 6282 N at 0.8 MPa for localized pressing operations, keeping pneumatic wiring compact and decentralized.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X225S-08B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore pushes 2513 N while the 100mm bore pushes 3927 N at 0.5 MPa. This DC24V terminal entry model includes a piston magnet for sensors. The default action retracts the rod when energized, but you can reposition the valve to extend on signal. Always operate within the 0.15-0.8 MPa valve range. The integrated valve routes air but does not function as a load lock; add an external rod lock or pilot-operated check valve to hold loads safely. For this 225mm stroke, ensure adequate side-load guidance using SC-series accessories.
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 SAUF100X225S-08B FAQ
It generates 3927 N push and 3681 N pull at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 4 cycles/s max) driven by a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
Yes. The default factory setting retracts the rod when the coil receives a signal. By physically repositioning the built-in 4M310 valve on the cap end, you can switch the action to extend-when-energized. Remember the valve only routes air; it will not hold a load without air pressure.
