The US Automatic 510010 is the acme screw assembly used inside select Patriot linear actuator arms. The acme screw is the mechanical drive member that turns motor rotation into controlled linear movement, allowing the actuator tube to extend and retract as the swing gate opens and closes. When this part wears, binds, or becomes damaged, the gate may move unevenly, stall under load, make grinding noises, fail to reach limits, or show excessive play in the actuator. Since the screw assembly works with the motor, gearbox, cover tube, limit system, and mounting geometry, the cause of failure should be checked before replacing the screw. A bent gate, tight hinge, poor bracket geometry, damaged cover tube, or contaminated actuator can shorten the life of the new screw assembly.
This compatibility list is based on known US Automatic Patriot service-part usage and should be verified against the original operator label, actuator parts diagram, and existing part number before ordering.
| Manufacturer | US Automatic |
|---|---|
| Product Type | Patriot actuator acme screw assembly |
| Part Number | 510010 |
| Application | Internal screw-drive replacement for Patriot linear actuator |
| Compatible Operator Type | US Automatic Patriot swing gate linear actuator |
| Material / Finish | Steel screw-drive assembly; verify by OEM part |
| Included Components | Acme screw assembly only unless listing states otherwise |
| Notes | Not a complete actuator arm |
If the acme screw failed because of a binding gate or worn hinges, replacing the screw alone may only be a temporary repair. Check gate balance, hinge drag, bracket geometry, and actuator tube damage before reassembly.
Internal actuator service can affect gate travel, limit adjustment, and safe stopping behavior. Disconnect power before service and have a qualified gate technician handle repairs if the actuator binds, the gate moves unexpectedly, or electrical damage is present.
It converts motor rotation into linear actuator movement so the Patriot swing gate arm can extend and retract.
No. It is an internal acme screw assembly, not the full Patriot actuator arm or motor assembly.
Replace it when the screw is worn, damaged, binding, stripped, or confirmed as the cause of poor actuator travel.
Inspect the cover tube, gaskets, motor, limit shaft, limit gear, limit switch assembly, and gate hinge condition.
Yes. A gate that does not swing freely can overload the actuator and damage internal drive components such as the acme screw.
