Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X160-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X160-08B 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 SAUF32X160-08B
The AirTAC SAUF32X160-08B 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 hard-anodized aluminum barrel is shorter than an ISO 15552 cylinder of the same bore, and the 1/8" cylinder port is fixed by the 32mm bore.
Operating within the 0.15-0.8 MPa valve window, it delivers 402 N push force at 0.5 MPa. The 1/4" valve port yields a 16 mm2 flow (Cv 0.89) with a 5 cycle/s limit. The DC24V terminal coil is IP65 rated. With a 402 N push force, the computed safe working load is roughly 241 N, and it can vertically lift about 20 kg 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 SAUF32X160-08B Is Used
Clamp Station Control
Decentralized clamping in machining cells where the integrated valve provides immediate local actuation without routing long air lines back to a central manifold.
Sorting Diverter Gate
Independent diverter control on a packaging conveyor, using the single coil signal to rapidly switch the 160mm stroke gate and save manifold space.
Compact Ejector Mechanism
Space-constrained ejection of parts from an assembly line, leveraging the shorter profile barrel and built-in 4M210 valve to minimize machine footprint.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF32X160-08B the Right Choice?
Size by checking both neighboring bores: this 32mm bore gives 402 N push at 0.5 MPa, whereas the 40mm bore gives 628 N. Confirm the DC24V terminal entry and PT threads suit your supply. The default action retracts the rod when energized, but repositioning the valve extends it on signal. Size force strictly within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve routes air but does not lock; add an external rod lock or pilot-operated check valve to hold loads. For this 160mm stroke, guide the mechanism to manage side loads. This SKU lacks a magnet and cannot take a sensor.
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 SAUF32X160-08B FAQ
It delivers 402 N push and 345 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5 cycles/s max) with a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
No, the built-in valve only routes air and is not a load lock; the piston drifts on air loss, so use an external rod lock or pilot-operated check valve to hold a load. By default the rod retracts when the coil is energized, but you can reconfigure it to extend on signal by repositioning the valve.
