Product Description
Double-Row Ball Slewing Ring Bearing Overview
Double-row ball slewing ring bearings with same diameter balls are engineered for demanding applications including wind turbine generators and concrete pump trucks. In wind energy applications, these bearings are installed at propeller bases for precise variable pitch control, requiring zero clearance, high starting friction moment, and exceptional running accuracy.
