Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 175mm stroke and a built-in 4M210-06 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 SAUF50X175S-06B
The SAUF50X175S-06B is a 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 extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. This unit includes a piston magnet for CMSG/DMSG/EMSG switches.
It features a 50mm bore, 1/4" cylinder port, M16x1.5 rod thread, and 21mm adjustable cushions. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78, and handles 5 cycles/sec. Operating pressure is 0.15-0.8 MPa, below the 1.0 MPa cylinder body rating. At 0.5 MPa it pushes 982N and pulls 825N, yielding a safe working load of roughly 589N and a vertical lift capacity of about 50kg 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 (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 SAUF50X175S-06B Is Used
Diverter Gate Control
Drives a localized diverter arm directly at the conveyor lane using one DC24V signal, removing the need to trace tubing back to a central manifold.
Decentralized Clamp Station
Actuates a clamping fixture independently on a large welding cell, saving manifold slots and simplifying pneumatic layouts.
Independent Product Pusher
Ejects items from a packaging line with a self-contained valve, cutting installation time and tubing clutter in tight machine spaces.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X175S-06B the Right Choice?
When sizing, compare neighboring bores: a 40mm bore offers 628N push while a 63mm bore provides 1559N at 0.5 MPa. This 50mm bore delivers 982N push and 825N pull at 0.5 MPa. Confirm the DC24V terminal entry coil meets your supply. The rod retracts when energized but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve window, not the 1.0 MPa body limit. The valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For this 175mm stroke, ensure adequate 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 SAUF50X175S-06B FAQ
It delivers 982N push and 825N pull at 0.5 MPa using a built-in 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/sec) with a DC24V terminal coil. The assembled unit operates at 0.15-0.8 MPa, even though the cylinder body rates to 1.0 MPa.
No, the built-in valve routes air and is not a lock. The rod drifts on air loss. For load holding, add an external rod lock or pilot-operated check valve. The default action retracts the rod when energized, but you can reposition the valve to extend on signal.
