VEVOR 0.75HP Electric Motor 1725 rpm, AC 115V/230V, 56 Frame, Air Compressor Motor Single Phase, 5/8" Keyed Shaft, CW/CCW Rotation for Agricultural Machinery and General Equipment

It boasts a big fan to keep it from overheating. Listed for pumps and agriculture machinery. I used mine for my hay elevator and no problems.

Current: 12.0/6.0A; synchronous speed 1800.

I did not find any reviews specifically addressing this question.

While the product description doesn't mention anything about continuous duty operation, customers mostly use it for things like air compressors and other equipment where motors run continuously. Many report it working well in those situations.

This product has ball bearings.
