Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-06A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-06A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 500mm 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 SAUF50X500-06A
The AirTAC SAUF50X500-06A is a double-acting profile cylinder with a built-in 4M210-06 5/2 solenoid valve on the cap. One AC220V coil signal drives the rod, eliminating remote valves and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" cylinder port, M16x1.5 rod thread, and 21mm adjustable cushions.
Operating strictly within the valve's 0.15-0.8 MPa window, it delivers 982N push force at 0.5 MPa. This yields a safe working load of roughly 589N and a vertical lift capacity of about 50kg with a 2:1 margin. The 1/8" valve port gives 14mm2 flow (Cv 0.78) at up to 5 cycles per second. Without a magnet suffix, this SKU 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 SAUF50X500-06A Is Used
Divert Gate Actuation
Decentralized diverters on a packaging line benefit from the integrated valve, cutting tubing runs to a central manifold.
Long-Reach Pusher
The 500mm stroke pushes cartons between zones, with the AC220V terminal connection simplifying machine wiring.
Standalone Clamp Station
A single coil signal drives the clamp, saving a valve island slot while delivering 982N force at 0.5MPa.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X500-06A the Right Choice?
Size force between the 40mm bore (628N push) and 63mm bore (1559N push) options, using the 0.5MPa figures. The 4M210-06 valve limits the assembled unit to 0.15-0.8 MPa despite the 1.0MPa cylinder body rating. Confirm the AC220V terminal entry suits your control system. By default the rod retracts when energised; repositioning the valve switches it to extend-when-energised. Because the 500mm stroke risks rod bending, use an external guide to manage side loads. The valve routes air and is not a lock—add an external rod lock or pilot-operated check valve for load holding.
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 SAUF50X500-06A FAQ
It delivers 982N push and 825N pull at 0.5MPa using a built-in 4M210-06 valve (1/8" port, Cv 0.78, 5 cycles/sec). The AC220V terminal coil runs on 0.15-0.8 MPa; never size the assembled SAUF at the 1.0MPa cylinder body limit.
Yes, you can reposition the valve to make the rod extend-when-energised instead of retract. The 5/2 valve only routes air, so it is not a load lock; the piston will drift on air loss and the cushion only decelerates near stroke end.
