Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-06A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 125mm 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 SAUF32X125S-06A
The SAUF32X125S-06A is a compact 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 32mm bore delivers 402N push and 345N pull at 0.5MPa, operating within the valve's 0.15-0.8MPa range.
This unit features a 1/8" valve port (Cv 0.78, 14mm2 flow) and a 1/8" cylinder port. It switches at up to 5 cycles/sec using an AC220V terminal entry coil (IP65, class B). The S suffix denotes a piston magnet for CMSG/DMSG/EMSG sensors. For sizing, expect a safe working load around 241N (60% of the 0.5MPa push force) 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 SAUF32X125S-06A Is Used
Clamp Actuation
Decentralized clamping on machining cells where one coil signal per actuator saves manifold space and tubing runs.
Diverting Gates
Independent diverting on packaging lines, using the built-in 4M210 valve to switch directly without a remote island.
Small Part Ejection
Ejecting parts from automated test fixtures, benefiting from the compact profile and 5 cycles/sec max frequency.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X125S-06A the Right Choice?
When sizing, compare this 32mm bore (402N push at 0.5MPa) against the 40mm bore (628N) to ensure adequate force. Verify the AC220V terminal entry coil matches your supply. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Always size within the 0.15-0.8MPa valve window, not 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 for holding. For this 125mm stroke, side-load is minimal, but always guide the load for strokes 300mm or above.
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 SAUF32X125S-06A FAQ
It features a 32mm bore, 125mm stroke, and a built-in 4M210-06 valve (1/8" port, Cv 0.78, 14mm2 flow). The AC220V terminal entry coil switches at up to 5 cycles/sec. It delivers 402N push force at 0.5MPa and must operate within the 0.15-0.8MPa valve pressure 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 allows flexible machine sequencing without altering your electrical control logic.
