Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 800mm 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 SAUF50X800-06A
The SAUF50X800-06A is a double-acting profile cylinder with a built-in AirTAC 4M210-06 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 uses a 1/4" cylinder port, a 1/8" valve port, and a Ø20mm rod with an M16x1.5 thread.
Operating within the valve's 0.15-0.8 MPa window, it delivers 982N push force at 0.5 MPa. The valve flows 14 mm2 (Cv 0.78) at up to 5 cycles/sec. For sizing, the safe working load is roughly 589N, and vertical lift capacity is about 50kg with a 2:1 margin. Because this SKU lacks the S suffix, it cannot accept a magnetic switch.

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 SAUF50X800-06A Is Used
Conveyor Diverter Gate
Decentralized diverter on a long conveyor line. The integrated valve switches the 800mm stroke directly at the actuator, removing long tube runs back to a central manifold.
Vertical Package Stacker
Lifting packages in a sorting hub. The 50mm bore provides a 50kg vertical lift capacity with a 2:1 safety margin at 0.5 MPa, driven by a single AC220V signal.
Machine Guard Door
Opening large equipment access doors. The self-contained 4M210-06 valve simplifies installation on moving door frames where routing manifold tubing is impractical.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X800-06A the Right Choice?
Size by comparing the 50mm bore (982N push at 0.5 MPa) against the 40mm (628N) and 63mm (1559N) options to match your load. Confirm the AC220V terminal entry and PT threads suit your controls. The rod retracts by default 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 body rating. The built-in valve routes air and is not a lock; add an external rod lock or pilot-operated check valve for held loads. At 800mm 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 SAUF50X800-06A FAQ
It generates 982N push and 825N pull at 0.5 MPa. The built-in valve is a 4M210-06 (5/2 solenoid) with 1/8" ports, 14 mm2 flow (Cv 0.78), and a 5 cycle/sec limit. The coil is AC220V with terminal entry. You must size force within the 0.15-0.8 MPa valve operating window, never the 1.0 MPa cylinder body rating.
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 on the cap. This self-switching design means no remote valve is needed, saving tubing and a manifold slot.
