Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 75mm 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 SAUF50X75S-06B
The SAUF50X75S-06B is a double-acting profile-type cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One coil signal drives the cylinder, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. The bore sets the cylinder air port at 1/4" and the rod-end thread at M16x1.5. A piston magnet is included for CMSG/DMSG/EMSG switches.
The integrated 4M210-06 valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and handles 5 cycles/sec. The coil is DC24V with terminal entry and IP65 protection. Although the cylinder body rates to 1.0 MPa, the assembled unit operates within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 982 N and pulls 825 N. For sizing, the safe working load is about 589 N, and it can vertically lift roughly 50 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 (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 SAUF50X75S-06B Is Used
Modular Clamping Station
Provides independent clamping on a machining line. The built-in valve removes the need for a central manifold, keeping the cell compact.
Decentralized Diverter Gate
Switches sorting gates directly at the conveyor. One DC24V signal actuates the gate, slashing tubing runs across the machine frame.
Independent Package Stopper
Acts as a localized stopper on a packing line. The integrated 4M210 valve allows standalone control without consuming manifold space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X75S-06B the Right Choice?
Size this 50 mm bore against its neighbours: a 40 mm bore yields 628 N push at 0.5 MPa, while a 63 mm bore yields 1559 N. This model delivers 982 N push and 825 N pull at 0.5 MPa. Confirm the DC24V terminal entry coil matches your supply. The rod retracts when the coil is energised; you can reconfigure it to extend-when-energised by repositioning the valve. Size force strictly within the 0.15-0.8 MPa valve operating window, never the 1.0 MPa cylinder body rating. The valve routes air and is not a lock—if you need to hold a load on air loss, add an external rod lock or pilot-operated check valve. For this 75 mm stroke side-load is minimal, but for strokes 300 mm or longer 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 SAUF50X75S-06B FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) driven by a DC24V terminal entry coil. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve. The valve only routes air—it does not lock the load, so add an external rod lock if you need to hold position on air loss.
