US Automatic 510350 Ranger 500 Actuator
The US Automatic 510350 is the complete replacement linear actuator used with select Ranger 500 swing gate opener systems. The actuator is the moving arm that mounts between the hinge post and the gate leaf, converting the operator command into controlled push/pull gate movement. This assembly is commonly ordered when the existing actuator has failed internally, has a damaged cable, has excessive mechanical wear, or no longer travels reliably even after battery, board, and gate-hardware problems have been ruled out. It is built around a 16 inch stroke and includes an 8 foot cable harness, so cable routing and control-box location matter. The actuator should be matched to the Ranger 500 parts diagram and installation geometry, especially on dual-gate systems where the cable and connector arrangement must match the correct gate leaf.
Common replacement reasons include stripped or noisy actuator movement, a damaged arm housing, failed internal motor or gear drive, damaged cable harness, water intrusion, or actuator travel that does not respond after control-board and power testing.

Technician Note
The Ranger actuator cable should not be casually spliced or extended without following the manufacturer guidance. Poor actuator cable splices can cause voltage drop, intermittent travel, false limit issues, and premature actuator failure.
Before Ordering Checklist
- Confirm the opener is a Ranger 500 system
- Match the 16 inch stroke and 8 foot cable harness
- Verify single or dual gate actuator position
- Inspect post and gate brackets for damage or misalignment
- Check battery, charger, board output, and gate swing before replacing the actuator
Professional Advisory
A swing gate actuator replacement should be followed by a full travel, obstruction, and safety-device check. If the gate is heavy, dragging, or electrically unsafe, use a qualified gate technician.
Important Ordering Warnings
This actuator should not be used to force a gate that is out of level, has bad hinges, or does not move freely by hand.
Product Questions and Answers
What is included with the 510350 actuator?
It is commonly listed as a complete Ranger 500 linear actuator with a 16 inch stroke and 8 foot cable harness.
Is this actuator for the Ranger 500 only?
It is primarily associated with select US Automatic Ranger 500 swing gate systems. Verify the parts diagram before using it on any other operator.
Can this actuator replace a Patriot arm?
No. Patriot and Ranger 500 actuator families are different and should not be interchanged unless specifically confirmed by US Automatic documentation.
What gate size is this actuator commonly associated with?
Listings commonly reference Ranger 500 applications up to 16 ft and 800 lb, but actual performance depends on gate condition, installation geometry, wind load, and accessories.
Should I replace the control board at the same time?
Not automatically. Test the board output, battery, charger, wiring, and actuator before replacing additional parts.
