When selecting a Power Swivel, the most critical factor is the Load Capacity, which should typically range from 150kg to 500kg depending on the application (e.g., heavy-duty recliners or industrial turntables). You must verify the Motor Type, prioritizing brushless DC motors for longevity and quieter operation (noise levels should be <50dB). Additionally, ensure the Rotation Degree meets your needs, whether it is a 360-degree continuous rotation or a limited angle with an auto-reset function. The material should be cold-rolled steel with a thickness of at least 2.5mm to prevent deformation under stress.
