Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-08B 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 SAUF32X225-08B
The SAUF32X225-08B is a compact double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The 32mm bore delivers 402N push and 345N pull at 0.5MPa, operating within the 0.15-0.8MPa valve window.
The integrated valve offers 1/4" porting, 16mm2 flow (Cv 0.89), and 5 cycles/sec. The cylinder body itself rates to 1.0MPa but the assembled unit is limited by the valve to 0.8MPa. Based on the 402N push figure, the safe working load is roughly 241N, translating to a vertical lift capacity of about 20kg with a 2:1 margin. This terminal-entry, PT-thread model has a 1/8" cylinder port, Ø12mm rod, and uses Ø8xØ5 PU tube.

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 SAUF32X225-08B Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running individual lines back to a central manifold is impractical, switching directly from one local DC24V signal.
Inline Diverters
Provides a self-contained actuation package for conveyor sorting gates, saving installation time and eliminating fragile tubing runs along the frame.
Compact Ejection
Fits neatly into multi-cavity ejection blocks, allowing each 32mm actuator to control its own 5/2 valve cycle without consuming manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225-08B the Right Choice?
When sizing, compare this 32mm bore (402N push at 0.5MPa) against the 40mm bore (628N push) for higher force needs. The 225mm stroke is well within the 1000mm maximum and above the 50mm minimum. Because this SKU lacks the -S magnet suffix, it cannot accept a magnetic switch for position sensing. The rod retracts when the coil is energised by default but can be reconfigured to extend by repositioning the valve. Remember the assembled unit operates at 0.15-0.8MPa, not the 1.0MPa cylinder body rating. The integrated valve routes air but does not lock the load; for vertical holding add an external rod lock or pilot-operated check valve. For this 225mm stroke, ensure adequate side-load guidance using SC-series accessories.
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 SAUF32X225-08B FAQ
It features a 32mm bore, 225mm stroke, and a built-in 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/sec). The DC24V terminal-entry coil delivers 402N push at 0.5MPa. Size the force within the 0.15-0.8MPa valve operating window, as the 1.0MPa cylinder body rating does not apply to the assembled unit.
No, the built-in 5/2 valve routes air but is not a load lock. The rod retracts when energised by default but can be set to extend by repositioning the valve. To hold a load securely on air loss, you must add an external rod lock or pilot-operated check valve.
