Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-06A 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 SAUF50X900-06A
The SAUF50X900-06A is a double-acting profile cylinder with a built-in AirTAC 4M210 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 unit of the same bore. This 50mm bore has a 1/4" cylinder port, an M16x1.5 rod thread, and 21mm adjustable cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 982N push at 0.5 MPa. The 1/8" valve port yields a 14 mm2 flow (Cv 0.78) and cycles up to 5 times per second. Based on the 0.5 MPa push force, the safe working load is roughly 589N, translating to a vertical lift capacity of about 50kg with a 2:1 margin. This SKU lacks a magnet and cannot accept a sensor.

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 SAUF50X900-06A Is Used
Decentralized Conveyor Divert
Mounts directly at the divert gate. One AC220V signal actuates the 900mm stroke without tubing back to a central manifold.
Long-Reach Pusher Arm
Ideal for pushing cartons across a wide roller bed. The self-contained valve minimizes install time on long traverses.
Independent Machine Gate
Operates a safety gate on a large machine cell. Saves a valve island slot and simplifies pneumatic plumbing.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X900-06A the Right Choice?
When sizing, compare this 50mm bore (982N push at 0.5 MPa) against the 40mm (628N) and 63mm (1559N) neighbors. Confirm the AC220V terminal entry and PT thread. The default action retracts the rod when energized; reposition the valve to extend on signal. 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 load lock; add an external rod lock or pilot-operated check valve to hold loads. For the 900mm stroke, use external guides 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 SAUF50X900-06A FAQ
It pushes 982N and pulls 825N 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. Although the cylinder body rates to 1.0 MPa, the assembled unit must operate at 0.15-0.8 MPa.
No, the 5/2 valve routes air but is not a load lock; the piston drifts without pressure. Use an external rod lock for holding. The default action retracts on energization, but you can reposition the valve to extend when energized.
