Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450S-08A 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-08A
The SAUF100X450S-08A is a double-acting profile-type cylinder with a built-in AirTAC 4M310-08 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 cylinder of the same bore. A piston magnet is included for position sensing.
Operating within the 0.15-0.8 MPa valve window, this 100mm bore delivers 3927N push at 0.5MPa. The 1/4" ported valve flows 25mm2 (Cv 1.4) at up to 4 cycles/sec. The coil is AC220V with terminal entry. Computed insight: safe working load is about 2356N (60% of the 0.5MPa push), yielding a 200kg vertical lift 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-08A Is Used
Machine Tool Clamping
Decentralized clamping on a large machining center. The built-in valve routes air locally, eliminating long tube runs back to a central manifold for each clamp.
Heavy Diverter Gate
Actuating a heavy diverter on a packaging line. One AC220V signal drives the 100mm bore directly at the station, saving manifold space and simplifying wiring.
Pallet Lift Station
Lifting pallets vertically. The integrated 4M310 valve supports up to 4 cycles/sec, while the piston magnet allows CMSG sensors to confirm lift positions.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X450S-08A the Right Choice?
Size both ways: this 100mm bore gives 3927N push at 0.5MPa, while the 80mm neighbour gives 2513N. Confirm the AC220V terminal entry and PT threads. Default action retracts the rod when energised; reposition the valve to extend-when-energised. Size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold loads. For the 450mm stroke, use external guides to prevent rod bending and side-load wear.
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-08A FAQ
It uses a built-in 4M310-08 5/2 valve (1/4" port, Cv 1.4, 25mm2 flow) with an AC220V terminal-entry coil. Push force is 3927N at 0.5MPa and 6282N at 0.8MPa. The cylinder body rates to 1.0MPa, but size force within the 0.15-0.8MPa valve operating window.
By default the rod retracts when the coil is energised; you can reposition the valve to extend-when-energised. The valve only routes air and is not a load lock. On air loss the piston drifts, so add an external rod lock or pilot-operated check valve for load holding.
