Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-08B is a genuine double-acting profile-type cylinder with a Ø32mm bore, 250mm 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 SAUF32X250-08B
The SAUF32X250-08B 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 unit of the same bore. The bore sets the 1/8" cylinder port and M10x1.25 rod thread.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 402 N push and 345 N pull at 0.5 MPa. The 1/4" valve port gives a 16 mm2 flow (Cv 0.89) at up to 5 cycles per second. With a DC24V terminal coil (IP65), expect a safe working load around 241 N, or a 20 kg vertical lift with a 2:1 margin. This SKU lacks a magnet, so it cannot accept 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 SAUF32X250-08B Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running individual lines to a central manifold is impractical, letting this actuator switch itself locally.
Inline Diverting
Perfect for small package diverters on conveyors, using the integrated 4M210 valve to achieve rapid 5 cycle/sec sorting without extra tubing.
Compact Gating
Suits tight machine cells where space is limited, using the short profile barrel and self-contained valve to actuate small gates independently.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X250-08B the Right Choice?
Size by force: this 32 mm bore pushes 402 N at 0.5 MPa, sitting between the larger 40 mm bore (628 N) and smaller options. Confirm the DC24V terminal coil and PT threads suit your control panel. The rod retracts when energised but you can reposition the valve to extend on signal. Always size within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. The routed air provides no load holding on pressure loss, so add an external rod lock or pilot-operated check valve for suspended loads. For this 250 mm stroke, ensure side-load guidance to prevent uneven 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 SAUF32X250-08B 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/sec max) running on DC24V. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend when energised simply by repositioning the built-in valve. This self-switching design means no remote valve is needed, saving tubing and manifold space.
