Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 450mm 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 SAUF50X450S-06B
The SAUF50X450S-06B is a double-acting profile cylinder with a built-in AirTAC 4M210-06 5/2 solenoid valve on the cap. One DC24V 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. This 50mm bore unit has a 1/4" cylinder port, an M16x1.5 rod thread, and a 450mm stroke with 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 0.5 MPa. The 4M210-06 valve offers 1/8" ports, 14mm2 flow (Cv 0.78), and 5 cycles/sec. For sizing, the safe working load is roughly 589N (60% of the 0.5MPa push), and vertical lift capacity is about 50kg with a 2:1 margin. Note the cylinder body rates to 1.0MPa, but the assembled unit is limited by the valve to 0.8MPa.

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 SAUF50X450S-06B Is Used
Divert Gate Actuation
Drives a decentralized lane diverter directly at the conveyor, needing only one coil signal and no remote valve manifold.
Packaging Pusher
Pushes cartons off a packing line using the integrated 4M210-06 valve, saving tubing and simplifying maintenance.
Independent Clamp Station
Clamps parts at a standalone machining cell, switching itself locally without consuming a slot on a central manifold.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X450S-06B the Right Choice?
Size by checking both neighbours: the 40mm bore gives 628N push at 0.5MPa, while the 63mm bore provides 1559N. This 50mm bore fits applications needing around 982N push at 0.5MPa. Confirm the DC24V terminal entry and PT threads meet your control specs. The rod retracts when energised but can be reconfigured to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve range, not the 1.0 MPa cylinder rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold loads. For this 450mm stroke, use external guides to prevent rod bending and side-load wear.
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 SAUF50X450S-06B FAQ
It pushes 982N and pulls 825N at 0.5MPa. The built-in valve is a 4M210-06 (1/8" port, Cv 0.78, 5 cycles/sec) running on DC24V. Although the cylinder body rates to 1.0MPa, the assembled unit must operate within the valve's 0.15-0.8 MPa window.
By default, the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the built-in valve. Because the valve only routes air, use an external rod lock or pilot-operated check valve if you need to hold a load.
