Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160-08B is a genuine double-acting profile-type cylinder with a Ø50mm 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 SAUF50X160-08B
The AirTAC SAUF50X160-08B is a double-acting profile cylinder with a built-in 4M210-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than a standard ISO 15552 unit of the same bore. This bore uses a 1/4" cylinder port and a Ø20 mm rod with an M16x1.5 thread.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 982 N push force at 0.5 MPa. The integrated valve provides 16 mm2 flow (Cv 0.89) and handles up to 5 cycles per second. For sizing, a safe working load is roughly 589 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 50 kg with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 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 SAUF50X160-08B Is Used
Decentralized Clamping
Ideal for distributed machining cells where routing a manifold to each clamp is impractical, letting one DC24V signal actuate the clamp directly.
Inline Diverters
Fits neatly into conveyor frames to power diverting gates without external valve plumbing, maximizing throughput in tight transfer spaces.
Compact Package Stops
Provides localized package stopping power in high-speed logistics sorters, saving manifold slots and minimizing pneumatic tubing runs.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160-08B the Right Choice?
When sizing, compare this 50 mm bore against its neighbours: a 40 mm bore yields 628 N push at 0.5 MPa, while a 63 mm bore provides 1559 N. This model delivers 982 N push and 825 N pull at 0.5 MPa. Confirm the DC24V terminal entry and PT threads meet your control spec. The rod retracts by default when energised; you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder body rating. Because the valve only routes air, add an external rod lock or pilot-operated check valve for load holding. For this 160 mm stroke, ensure standard side-load guidance.
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 SAUF50X160-08B FAQ
It generates 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-08 (1/4" port, Cv 0.89, 5/2 solenoid) running on DC24V. Although the cylinder body rates to 1.0 MPa, you must size force within the valve's 0.15-0.8 MPa operating window.
This specific SKU lacks a magnet, so it cannot accept a magnetic switch. The valve defaults to retracting the rod when energised, but you can reconfigure it to extend-when-energised simply by repositioning the valve.
