Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 125mm 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 SAUF32X125-08A
The SAUF32X125-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore. This SKU uses terminal entry and has no magnet, so it cannot accept a magnetic switch.
It delivers 402 N push and 345 N pull at 0.5 MPa. The integrated valve flows 16 mm2 (Cv 0.89) at a 1/4" port, cycling up to 5 times per second. Size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. For sizing, the safe working load is roughly 241 N, and it can vertically lift about 20 kg with a 2:1 margin.

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 SAUF32X125-08A Is Used
Compact Clamping Station
Decentralized clamping on a machining line where the integrated valve saves manifold space and simplifies tubing.
Package Divert Gate
Directs small cartons on a conveyor; the 5 cycles per second valve speed matches high throughput sorting.
Component Pusher
Pushes lightweight parts into a fixture using one AC220V signal, removing the need for a remote valve bank.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125-08A the Right Choice?
When sizing, compare this 32 mm bore against the 40 mm neighbor: the 40 mm bore yields 628 N push at 0.5 MPa versus 402 N here, offering a step up if your load exceeds the 241 N safe working estimate. Confirm the AC220V terminal entry matches your supply. The rod retracts when the coil is energised, but you can reposition the valve to extend on signal. Because the valve routes air, it is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 125 mm stroke side-load is minimal, but any stroke over 300 mm requires a guide. The cylinder port is 1/8".
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 SAUF32X125-08A 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) running on AC220V. Although the cylinder body rates to 1.0 MPa, the assembled unit operates strictly within the 0.15-0.8 MPa valve window.
By default the rod retracts when the coil is energised; you can reposition the valve to make it extend instead. The valve only routes air, so it is not a load lock. The piston will drift on air loss, requiring an external rod lock or pilot-operated check valve to hold position.
