Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-06A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 225mm stroke and a built-in 4M210-06 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 SAUF32X225-06A
The SAUF32X225-06A is a compact double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One AC220V 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, and it uses SC-series mounting accessories.
Operating within the 0.15-0.8 MPa valve window, this 32mm bore generates 402N push and 345N pull at 0.5 MPa. The 1/8" ported valve flows 14 mm2 (Cv 0.78) at up to 5 cycles per second. For sizing, the safe working load is roughly 241N (about 60% of the 0.5MPa push), allowing a 20kg vertical lift with a 2:1 margin. The cylinder body rates to 1.0 MPa, but the integrated valve limits the assembled unit to 0.8 MPa. This terminal-entry, PT-thread SKU lacks a magnet (-S), so it cannot accept 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 (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 SAUF32X225-06A Is Used
Decentralized Clamping
Ideal for a multi-station clamping fixture where running individual air lines to a central manifold is impractical, letting this 32mm actuator switch itself directly at the point of operation.
Inline Divert Gate
Perfect for a compact conveyor divert gate that needs a single AC220V signal to actuate, saving space and eliminating the need for a dedicated remote valve island.
Independent Pick Place
Suits a standalone pick-and-place unit where integrated switching simplifies wiring and tubing, avoiding the complexity of a full pneumatic manifold for one motion axis.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-06A the Right Choice?
Size this 32mm bore against the neighbouring 40mm option: the 40mm yields 628N push at 0.5 MPa versus 402N here. Confirm the AC220V terminal entry and PT thread match your control scheme. The default action retracts the rod when energised; repositioning the valve switches it to extend-when-energised. Size all forces within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. With a 225mm stroke, provide side-load guidance to prevent rod bending.
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 SAUF32X225-06A FAQ
It pushes 402N and pulls 345N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) running on an AC220V terminal-entry 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. The 1/8" cylinder port and M10x1.25 rod end are fixed by the 32mm bore.
By default the rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised. The 5/2 valve routes air but does not lock the piston; on air loss the rod drifts. For load holding, install an external rod lock or pilot-operated check valve. Also, this specific SKU lacks a magnet, so it cannot accept magnetic sensors.
