Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50S-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50S-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 50mm 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 SAUF50X50S-06A
The SAUF50X50S-06A is an extruded aluminum profile-type double-acting 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 50mm bore uses a 1/4" cylinder port, a Ø20mm rod with an M16x1.5 thread, and 21mm adjustable cushions. The S suffix means a piston magnet is present for CMSG/DMSG/EMSG switches.
This model features a 4M210-06 valve with a 1/8" port, 14 mm2 flow (Cv 0.78), and a 5 cycle/s limit. The coil is AC220V with terminal entry (IP65). While the cylinder body rates to 1.0 MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window. At 0.5 MPa it pushes 982 N and pulls 825 N. The computed safe working load is ~589 N (about 60% of the 0.5 MPa push force), offering a vertical lift capacity of ~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 SAUF50X50S-06A Is Used
Decentralized Clamping
Ideal for a machining cell where each clamping station needs independent control without running long tubing back to a central manifold.
Inline Diverters
Perfect for conveyor sorting gates that require a single coil signal to actuate, reducing wiring complexity on the line.
Package Stops
Deploy at individual packing stations to raise package stops on command, saving a valve manifold slot in the control panel.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X50S-06A the Right Choice?
Size by comparing neighbor bores: a 40mm bore yields 628 N push at 0.5 MPa, while a 63mm bore yields 1559 N. This 50mm bore provides 982 N push and 825 N pull at 0.5 MPa. Confirm the AC220V terminal entry and PT threads match your supply. The default action retracts the rod when energized, but you can reposition the valve to extend-when-energized. Always size force within the 0.15-0.8 MPa valve range, never the 1.0 MPa cylinder body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For this 50mm stroke, side-load guides are not critical, but they are recommended for strokes over 300mm.
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 SAUF50X50S-06A FAQ
It delivers 982 N push and 825 N pull at 0.5 MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/s max) with an AC220V terminal coil (IP65). Although the cylinder body rates to 1.0 MPa, the assembled unit must operate within the 0.15-0.8 MPa valve window.
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 one-signal operation means no remote valve is needed, saving installation time and tubing.
