Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 450mm 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 SAUF100X450S-08B
The SAUF100X450S-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 makes it shorter than an ISO 15552 cylinder of the same bore. This 100mm bore version has a 1/2" cylinder port, a 25mm rod, and a 450mm stroke with a piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve features a 1/4" port, 25 mm2 flow (Cv 1.4), and runs at 4 cycles/sec. It operates on DC24V with terminal entry. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 3927 N and pulls 3681 N. A practical computed insight: the safe working load is about 2356 N (60% of the 0.5 MPa push), allowing a vertical lift of roughly 200 kg 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 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 SAUF100X450S-08B Is Used
Decentralized Press Clamps
Uses one coil signal per actuator to clamp heavy parts, removing the need for a central manifold and long tubing runs.
Independent Diverters
Mounts directly on diverter arms to push products at 4 cycles/sec without routing separate control lines back to a main panel.
Vertical Lift Gates
Lifts loads up to 200 kg with a 2:1 margin using the integrated 4M310 valve, saving installation space on large storage machines.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450S-08B the Right Choice?
When sizing, compare neighboring bores: the 80mm bore yields 2513 N push while the 100mm bore provides 3927 N at 0.5 MPa. Confirm your coil is DC24V with terminal entry. 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, never the 1.0 MPa cylinder body rating. Because routing air is not locking, add an external rod lock or pilot-operated check valve to hold loads. For this 450mm stroke, use external guides to prevent rod bending and side-load wear. PU tube size is Ø10xØ6.5.
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 SAUF100X450S-08B FAQ
It generates 3927 N push and 3681 N pull at 0.5 MPa. The built-in valve is a 4M310-08 (1/4" port, Cv 1.4, 25 mm2 flow) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
No, the 5/2 valve only routes air and is not a lock. The rod drifts on air loss. The default action retracts when energized, but you can reposition the valve to extend on signal. For load holding, install an external rod lock or pilot-operated check valve.
