510010 US Automatic Patriot Actuator Acme Screw Assembly
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.

Technician Note
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.
Before Ordering Checklist
- Confirm the actuator is a Patriot swing gate linear actuator.
- Verify the old screw assembly part number or parts diagram reference is 510010.
- Inspect the 510020 cover tube for dents or corrosion.
- Check the actuator motor, gearbox, gaskets, and limit components for related wear.
- Confirm the gate swings freely by hand before returning the actuator to service.
Professional Advisory
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.
Product Questions & Answers
What does the 510010 acme screw assembly do?
It converts motor rotation into linear actuator movement so the Patriot swing gate arm can extend and retract.
Is 510010 a complete actuator?
No. It is an internal acme screw assembly, not the full Patriot actuator arm or motor assembly.
When should this screw assembly be replaced?
Replace it when the screw is worn, damaged, binding, stripped, or confirmed as the cause of poor actuator travel.
What other parts should be inspected with the acme screw?
Inspect the cover tube, gaskets, motor, limit shaft, limit gear, limit switch assembly, and gate hinge condition.
Can a heavy or dragging gate damage this part?
Yes. A gate that does not swing freely can overload the actuator and damage internal drive components such as the acme screw.
