Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-08A is a genuine double-acting profile-type cylinder with a Ø50mm 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 SAUF50X175-08A
The SAUF50X175-08A is a double-acting profile-type cylinder with a built-in AirTAC 4M210-08 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 is shorter than an ISO 15552 cylinder of the same bore. It features a 50mm bore, 175mm stroke, 1/4" cylinder port, and an M16x1.5 rod thread.
The integrated valve supplies a 1/4" port with 16mm2 flow (Cv 0.89) and switches up to 5 cycles/sec. The AC220V terminal-entry coil is IP65 rated with a 0.05s response. Size force within the valve's 0.15-0.8 MPa window; at 0.5 MPa it pushes 982N and pulls 825N. This yields a safe working load of roughly 589N, capable of a 50kg vertical lift with a 2:1 margin. Note this SKU lacks a magnet and cannot take 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 SAUF50X175-08A Is Used
Diverter Gate Actuation
Decentralized sorting line diverter where the integrated valve eliminates long tube runs back to a central manifold, allowing rapid 5 cycles/sec sorting directly at the conveyor.
Independent Clamping Station
Single-station clamping on a multi-station fixture; one AC220V coil signal controls the clamp without consuming a slot on the main valve island.
Carton Flap Folder
Compact packaging machine folder using the 175mm stroke to fold flaps, saving install time by mounting the 4M210-08 valve directly on the cylinder cap.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175-08A the Right Choice?
Size by checking both neighboring bores: a 40mm bore gives 628N push while a 63mm bore gives 1559N at 0.5 MPa. This 50mm bore provides 982N push and 825N pull at 0.5 MPa. Always size within the 0.15-0.8 MPa valve operating window, not the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry matches your supply. The rod retracts when energized but can be reconfigured to extend by repositioning the valve. Because this SKU lacks a magnet, it cannot accept a sensing switch. The valve routes air and does not lock the load; add an external rod lock or pilot-operated check valve for holding. For this 175mm stroke, guide the load to manage side-load stress.
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 SAUF50X175-08A FAQ
It pushes 982N and pulls 825N at 0.5 MPa. The built-in valve is a 4M210-08 (5/2 solenoid) with a 1/4" port, 16mm2 flow (Cv 0.89), and a 5 cycles/sec max frequency. The coil is AC220V with terminal entry. You must size force within the valve's 0.15-0.8 MPa operating window, even though the cylinder body rates to 1.0 MPa.
By default the rod retracts when the coil is energized; you can reconfigure it to extend-when-energised by repositioning the valve. The valve only routes air and is not a lock. If air is lost, the piston drifts and the cushion only decelerates near stroke end. For load holding, install an external rod lock or pilot-operated check valve.
