Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X175S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X175S-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 SAUF32X175S-08A
The SAUF32X175S-08A 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 pushes 402N at 0.5MPa within the 0.15-0.8MPa valve window. It includes a piston magnet for position sensing.
The integrated valve delivers 1/4" port flow of 16mm2 (Cv 0.89) at up to 5 cycles/s. The AC220V terminal entry coil is IP65 rated. Based on the 402N push force, the safe working load is roughly 241N, translating to a 20kg vertical lift with a 2:1 margin. The cylinder body rates to 1.0MPa, but the assembled unit operates strictly at 0.15-0.8MPa.

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 SAUF32X175S-08A Is Used
Decentralized Clamping
Ideal for distributed machining cells where each clamping station switches itself directly from one AC220V signal, eliminating long tube runs back to a central manifold.
Inline Diverting
Perfect for conveyor diverters requiring rapid actuation; the 4M210 valve handles 5 cycles/s, and the compact profile fits tight transfer spaces.
Independent Pick-and-Place
Enables standalone pick-and-place units on large assembly machines, saving manifold slots and simplifying installation with its integrated switching.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X175S-08A the Right Choice?
Size by checking both neighbouring bores against the 0.5MPa force figures: this 32mm bore pushes 402N, while stepping up to a 40mm bore yields 628N. Confirm the AC220V terminal entry coil matches your supply. The rod retracts when energised by default; reposition the valve to extend on signal. Size all forces within the 0.15-0.8MPa valve range, not the 1.0MPa cylinder body rating. The valve routes air and is not a lock; for load holding on air loss, add an external rod lock or pilot-operated check valve. For this 175mm stroke, ensure external guidance to manage side loads.
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 SAUF32X175S-08A FAQ
It pushes 402N and pulls 345N at 0.5MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on AC220V. The cylinder body rates to 1.0MPa, but the assembled unit operates strictly within the 0.15-0.8MPa valve window. The cylinder air port is 1/8".
By default the rod retracts when energised, but you can reconfigure it to extend by repositioning the valve. The valve only routes air; it is not a load lock. The piston will drift on air loss, so add an external rod lock or pilot-operated check valve if you need to hold a load.
