Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 450mm stroke and a built-in 4M210-08 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 SAUF32X450-08B
The SAUF32X450-08B is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the rod, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It has a 32mm bore, 1/8" cylinder port, and a 450mm stroke.
The integrated valve has a 1/4" port, 16mm2 flow (Cv 0.89), and switches up to 5 cycles/sec. It runs on DC24V with terminal entry. The cylinder body rates to 1.0 MPa, but the valve limits operation to 0.15-0.8 MPa. At 0.5 MPa it pushes 402N and pulls 345N. This yields a safe working load of about 241N, or a 20kg vertical lift with a 2:1 margin. This SKU lacks a magnet, so it cannot take a sensor.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 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 SAUF32X450-08B Is Used
Decentralized Clamping
Drives independent clamps across a large fixture using one DC24V signal per actuator, removing long tube runs back to a central manifold.
Zone Diverters
Powers individual diverting gates on a conveyor line, saving manifold slots and simplifying installation with the integrated 4M210 valve.
Component Pushers
Pushes parts into test nests at up to 5 cycles/sec, relying on the built-in valve to keep control wiring local to the actuator.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X450-08B the Right Choice?
Size by checking both neighboring bores: the 32mm bore gives 402N push at 0.5 MPa, while a 40mm bore gives 628N. Confirm your coil is DC24V with terminal entry. The rod retracts when energized but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve window, never the 1.0 MPa cylinder rating. The valve only routes air, so add an external rod lock or pilot-operated check valve to hold a load. For this 450mm stroke, use an external guide 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 SAUF32X450-08B FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly in a 0.15-0.8 MPa window.
Yes, the default action retracts the rod when energized, but you can reposition the valve to make it extend when energized. The valve only routes air; it is not a lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve to hold a load.
