Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 300mm 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 SAUF32X300S-08A
The SAUF32X300S-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, saving a manifold slot and tubing for decentralized setups. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This unit has a 300mm stroke and a piston magnet for CMSG/DMSG/EMSG switches.
It features a 32mm bore, 1/8" cylinder port, and an M10x1.25 rod thread. The integrated valve has a 1/4" port with a Cv of 0.89 and cycles up to 5 times per second. The AC220V terminal entry coil is IP65 rated. Size forces within the 0.15-0.8 MPa valve window, not the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 402N and pulls 345N, giving a safe working load of roughly 241N or a 20kg vertical lift 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 SAUF32X300S-08A Is Used
Decentralized Clamping
Ideal for distributed clamping stations where running a manifold line is costly; the integrated valve switches the clamp directly from one AC220V signal.
Inline Diverters
Perfect for conveyor sorting gates that need independent control without extra plumbing, utilizing the 5 cycles per second response rate.
Compact Part Ejection
Fits into tight machine cells to push parts off a line, saving manifold space while providing position feedback via the magnetic piston.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X300S-08A the Right Choice?
When sizing, compare this 32mm bore against the 40mm neighbor which pushes 628N at 0.5 MPa. This 32mm unit provides 402N push and 345N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT threads match your supply. The cylinder body rates to 1.0 MPa but the assembled unit must operate in the 0.15-0.8 MPa valve range. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. The 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 300mm stroke, use external guides to prevent rod bending and side-load 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 SAUF32X300S-08A FAQ
It pushes 402N and pulls 345N 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 must operate within the 0.15-0.8 MPa valve window. The cylinder port is 1/8".
No, the built-in valve routes air but is not a lock. The rod retracts when energised by default but can be set to extend by repositioning the valve. For vertical load holding, install an external rod lock or pilot-operated check valve.
