Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-06A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 225mm stroke and a built-in 4M210-06 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-06A
The SAUF32X225S-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One AC220V terminal coil signal drives the actuator directly, eliminating remote plumbing and saving a manifold slot. The hard-anodized aluminum barrel is shorter than an ISO 15552 cylinder of the same bore, and the -S suffix provides a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the 0.15-0.8 MPa valve window, this 32mm bore generates 402N push and 345N pull at 0.5 MPa. The integrated 4M210-06 valve features a 1/8" port, Cv 0.78 flow, and 5 cycles/sec. The cylinder port is 1/8" with an M10x1.25 rod thread. For sizing, the safe working load is roughly 241N, and vertical lift capacity is about 20kg 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 SAUF32X225S-06A Is Used
Compact Clamping Station
Ideal for decentralized clamping where the built-in 4M210 valve switches the 32mm actuator directly from a single AC220V signal, saving manifold space.
Package Diverter Gate
Provides localized diverting action on a conveyor. The integrated valve minimizes tubing runs back to a central control panel, speeding up assembly.
Small Part Ejection
Delivers fast ejection in tight machine cells. The 5 cycles/sec valve frequency and 225mm stroke handle repetitive small-part rejection tasks efficiently.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X225S-06A the Right Choice?
When sizing, compare this 32mm bore (402N push at 0.5 MPa) against the neighboring 40mm bore (628N push) to ensure adequate force. The safe working load is approximately 241N, yielding a 20kg vertical lift capacity with a 2:1 margin. Confirm the AC220V terminal entry and PT thread meet your electrical specs. The assembled unit operates strictly in the 0.15-0.8 MPa range; although the cylinder body rates to 1.0 MPa, the valve limits the assembly. The rod retracts when energized by default, but you can reposition the valve to extend on signal. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 225mm stroke, provide 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 SAUF32X225S-06A FAQ
It delivers 402N push and 345N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78) 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.
By default the rod retracts when energized, but you can reposition the valve to extend on signal. The valve only routes air; it is not a lock, so you must add an external rod lock or pilot-operated check valve to hold a load securely.
