Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 125mm 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 SAUF50X125S-06A
The SAUF50X125S-06A is a double-acting profile-type cylinder with a built-in AirTAC 4M 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. It features a 50mm bore, 125mm stroke, and a piston magnet for CMSG/DMSG/EMSG switches.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982N push and 825N pull at 0.5MPa. The integrated 4M210-06 valve has a 1/8" port, Cv 0.78 flow, and handles up to 5 cycles/sec. The cylinder port is 1/4". Computed buyer insight: safe working load is ~589N (about 60% of the 982N push), offering a vertical lift capacity of ~50kg with a 2:1 margin. The AC220V terminal coil is IP65 rated.

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 SAUF50X125S-06A Is Used
Decentralized Clamping
Ideal for clamping stations on a large machining line where running individual air lines back to a central manifold is impractical.
Inline Diverters
Powers sorting gates directly at the conveyor frame using one AC220V signal, eliminating the need for a nearby remote valve bank.
Package Stops
Controls independent package stops across a wide distribution hub, saving manifold slots and simplifying tubing for each actuator.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X125S-06A the Right Choice?
Size by checking both neighboring bores: the 40mm bore yields 628N push at 0.5MPa, while the 63mm bore provides 1559N. This 50mm bore gives 982N push and 825N pull at 0.5MPa. Always size force within the built-in valve's 0.15-0.8 MPa operating range, never the 1.0 MPa cylinder body rating. Confirm the AC220V terminal entry and PT thread meet your electrical specs. The rod retracts when the coil is energized; reposition the valve to reverse this to extend-when-energized. Because the valve only routes air, add an external rod lock or pilot-operated check valve to hold loads safely. For this 125mm stroke, side-load is minimal, but for strokes >=300mm use a guide to prevent rod binding.
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 SAUF50X125S-06A FAQ
It delivers 982N push and 825N pull at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec max) driven by an AC220V terminal coil. You must size the force within the valve's 0.15-0.8 MPa operating window, not the 1.0 MPa cylinder body rating.
By default, the rod retracts when the coil is energized. You can reconfigure it to extend-when-energized simply by repositioning the built-in valve. This self-switching design means one coil signal drives the cylinder directly, with no remote valve required.
