Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 225mm 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 SAUF32X225-08A
The SAUF32X225-08A is a compact double-acting profile cylinder with a built-in AirTAC 4M210 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 unit of the same bore. It uses a 1/8" cylinder port and a 1/4" valve port.
Size force within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 402 N and pulls 345 N. The 4M210-08 valve flows 16 mm2 (Cv 0.89) at up to 5 cycles/s. For sizing, a safe working load is roughly 241 N (about 60% of the 402 N push), and it can vertically lift around 20 kg with a 2:1 margin. This terminal-entry, PT-thread SKU lacks a magnet, so it cannot take 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 SAUF32X225-08A Is Used
Modular Assembly Stations
Dedicated one-valve-per-actuator control for independent clamping modules without routing long tube lines back to a central manifold.
Diverter Gates
Self-switching diverters on conveyors where installing a remote valve island is impractical or too costly to plumb.
Compact Testing Rigs
Space-constrained functional test fixtures that benefit from the short profile barrel and integrated 5/2 valve on the cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-08A the Right Choice?
When sizing, compare both ways: the 32 mm bore gives 402 N push at 0.5 MPa, while the next size up (40 mm) yields 628 N. Confirm this terminal-entry AC220V coil matches your supply. The rod retracts when energised, but you can reconfigure it to extend-when-energised by repositioning the valve. Always operate within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The built-in valve routes air but is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 225 mm stroke, guide the rod end to manage side loads.
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 SAUF32X225-08A FAQ
It pushes 402 N and pulls 345 N at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) driven by an AC220V terminal-entry coil. Although the cylinder body rates to 1.0 MPa, you must size force within the 0.15-0.8 MPa valve operating window.
By default the rod retracts when the coil is energised, but you can reconfigure it to extend-when-energised by repositioning the valve. The valve only routes air and is not a load lock; the piston will drift on air loss. Use an external rod lock or pilot-operated check valve for load holding.
