Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X160-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X160-08A is a genuine double-acting profile-type cylinder with a Ø32mm bore, 160mm 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 SAUF32X160-08A
The AirTAC SAUF32X160-08A is a double-acting profile cylinder with a built-in 4M210 5/2 solenoid valve on the cap. One coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. This 32mm bore uses a 1/8" cylinder port and a 12mm rod with an M10x1.25 thread.
The integrated 4M210-08 valve features a 1/4" port, 16mm2 flow (Cv 0.89) and runs up to 5 cycles/sec. The AC220V terminal entry coil is IP65 rated with a 0.05s response. Though the cylinder body rates to 1.0MPa, the valve limits operation to 0.15-0.8MPa. At 0.5MPa it pushes 402N and pulls 345N. The computed safe working load is roughly 241N, allowing a vertical lift of about 20kg with a 2:1 margin. This SKU lacks a magnet, so it cannot take 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 SAUF32X160-08A Is Used
Decentralized Clamping
Ideal for a multi-station clamping fixture where running individual lines to a central manifold is impractical, switching directly from one AC220V signal.
Inline Divert Gate
Perfect for a short-stroke divert gate on a packaging line, saving tubing and installation time by mounting the 4M210 valve directly on the cap.
Compact Ejection Station
Fits neatly into a tight machine cell for ejecting small parts, using the integrated 5/2 valve to cycle up to 5 times per second without extra plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X160-08A the Right Choice?
Size by force: this 32mm bore pushes 402N at 0.5MPa, sitting between the 40mm bore (628N) and smaller actuators. Always size within the 0.15-0.8MPa valve window, not the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry coil meets your supply. The rod retracts when energised by default, but you can reconfigure it to extend by repositioning the valve. The built-in valve routes air and does not hold the load on pressure loss; add an external rod lock or pilot-operated check valve for suspended loads. For this 160mm stroke, side-load is minimal, but always guide the rod end. This non-magnet version cannot accept sensors.
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 SAUF32X160-08A 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, 5/2 solenoid) running on an AC220V terminal coil. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8MPa range.
Yes. The default action retracts the rod when energised, but you can reposition the valve on the cap to make it extend instead. This self-switching design means you need only one coil signal and no remote valve, simplifying control wiring.
