Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X175-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X175-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 175mm 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 SAUF32X175-08A
The SAUF32X175-08A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One coil signal drives the rod, 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 32mm bore generates 402N push and 345N pull at 0.5MPa, with a 1/8" cylinder port and an M10x1.25 rod thread.
The integrated valve offers 1/4" porting, 16mm2 flow (Cv 0.89), and 5 cycles/sec. It runs on AC220V via terminal entry. Size force within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. Based on the 0.5MPa push force, the safe working load is roughly 241N, allowing a vertical lift of about 20kg with a 2:1 margin. This SKU lacks the S magnet suffix, so it cannot accept a magnetic switch.

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 SAUF32X175-08A Is Used
Decentralized Clamping
Ideal for clamping stations on a large machining line where running individual air lines to a central manifold is impractical.
Inline Diverting
Provides a compact diverter arm on a packaging conveyor, switching itself locally with one AC220V signal.
Independent Pick-and-Place
Perfect for a small independent pick-and-place head that needs to save space and avoid complex valve manifold wiring.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X175-08A the Right Choice?
When sizing, compare neighboring bores: a 40mm bore yields 628N push versus 402N here, while smaller units lack the thrust. Confirm the AC220V coil and terminal entry match your control system. The rod retracts when energized by default, but you can reconfigure it to extend by repositioning the valve. Always operate within the 0.15-0.8MPa valve pressure range. The valve routes air but does not function as a load lock; add an external rod lock or pilot-operated check valve to hold loads securely. For this 175mm stroke, side loads are minimal, but ensure proper guiding for longer extensions.
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 SAUF32X175-08A FAQ
It delivers 402N push and 345N pull at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/sec) running on AC220V. Although the cylinder body rates to 1.0MPa, you must size force within the 0.15-0.8MPa valve operating window.
No, the built-in valve routes air and is not a load lock; the piston will drift on air loss. Add an external rod lock or pilot-operated check valve for holding. By default, the rod retracts when the coil is energized, but you can reconfigure it to extend-when-energised by repositioning the valve.
