Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-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 SAUF32X225S-08A
The SAUF32X225S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210 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. The bore dictates a 1/8" cylinder port and an M10x1.25 rod thread, while the valve port is 1/4". A piston magnet is included for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, this 32mm bore delivers 402N push and 345N pull at 0.5MPa. The 4M210-08 valve provides 16mm2 flow (Cv 0.89) and cycles up to 5 times per second. For sizing, the safe working load is roughly 241N, and it can vertically lift about 20kg with a 2:1 margin. The AC220V terminal entry coil is IP65 rated with a 0.05s response. The cylinder body rates to 1.0MPa, but the assembled unit is limited by the valve to 0.8MPa.

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 SAUF32X225S-08A Is Used
Compact Part Ejection
Ideal for decentralized ejection stations where routing a remote valve line is difficult; the integrated 4M210 valve switches the 32mm bore directly from one AC220V signal.
Inline Diverter Gate
Perfect for mounting a diverter on a conveyor frame. The profile barrel saves space, while the built-in valve eliminates a dedicated manifold block for the actuator.
Small Component Clamping
Provides 402N of push force for clamping small parts. The -S piston magnet allows CMSG/DMSG/EMSG switches to confirm clamp position at the workstation.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-08A the Right Choice?
When sizing this model, compare it against the neighboring 40mm bore if you need more force, as the 40mm yields 628N push at 0.5MPa versus the 32mm's 402N. Confirm your coil voltage is AC220V with terminal entry. The rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. Always size force within the 0.15-0.8 MPa valve range, never the 1.0MPa cylinder body rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 225mm stroke, which is below the 300mm side-load threshold, standard SC-series mounting accessories provide adequate support without needing an external guide.
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 SAUF32X225S-08A FAQ
It uses a built-in 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/s max) on an AC220V terminal entry coil. The 32mm bore generates 402N push and 345N pull at 0.5MPa. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa window.
No, the built-in valve only routes air and is not a lock; the piston will drift on air loss and the cushion only decelerates near stroke end. Add an external rod lock or pilot-operated check valve for holding. By default the rod retracts when energized, but you can reposition the valve to extend-when-energized.
