Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-06B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-06B is a genuine double-acting profile-type cylinder with a Ø50mm bore, 900mm 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 SAUF50X900-06B
The SAUF50X900-06B is a double-acting profile-type cylinder with a built-in AirTAC 4M210 5-port 2-position solenoid valve mounted on the cap. One coil signal drives the cylinder, 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 SKU lacks a magnet, so it cannot take a magnetic switch.
It delivers 982 N push and 825 N pull at 0.5 MPa. The safe working load is about 589 N, and it can vertically lift roughly 50 kg with a 2:1 margin. The 4M210-06 valve has a 1/8" port, 14 mm2 flow (Cv 0.78), and runs up to 5 cycles per second. The cylinder body rates to 1.0 MPa, but you must size force within the valve's 0.15-0.8 MPa window. The bore's air port is 1/4".

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 SAUF50X900-06B Is Used
Decentralized Conveyor Divert
Mounts directly at a lane diverter on a long conveyor line, using the integrated 4M210 valve to switch the 900 mm stroke without running long tubing back to a central manifold.
Remote Machine Guard Gate
Drives a 50 mm bore safety gate far from the control cabinet. The single DC24V coil signal simplifies wiring while providing 982 N push force at 0.5 MPa.
High-Reach Packaging Pusher
Pushes cartons from a high-level packaging zone using the 900 mm stroke. The built-in valve handles 5 cycles per second, and the profile barrel saves vertical space.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-06B the Right Choice?
Size this 50 mm bore against the neighbours: a 40 mm bore gives 628 N push at 0.5 MPa, while a 63 mm bore gives 1559 N. This model provides 982 N push at 0.5 MPa. Confirm the DC24V terminal entry and PT threads suit your setup. The default action retracts the rod when energised, but you can reconfigure it to extend by repositioning the valve. The assembled unit operates strictly at 0.15-0.8 MPa, never the 1.0 MPa cylinder body rating. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For the 900 mm stroke, use an external guide to prevent rod bending and side-load damage.
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 SAUF50X900-06B FAQ
It generates 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, 5/2 solenoid) running on a DC24V terminal coil. Although the cylinder body rates to 1.0 MPa, the assembled unit operates within a 0.15-0.8 MPa window.
The valve routes air and is not a load lock, so the piston drifts on air loss; add an external rod lock or pilot-operated check valve to hold a load. By default the rod retracts when the coil is energised, but you can reposition the valve to make it extend when energised.
