Slewing bearings comprise an inner ring and an outer ring, one of which usually incorporates a gear. Together with attachment holes in both rings, they enable an optimized power transmission with a simple and quick connection between adjacent machine components. The bearing raceways, in conjunction with the rolling elements and cages or spacers, are designed to accommodate loads acting singly or in combination, and in any direction.

Our products are ranging from 200mm to 5000mm, which mainly apply for tunneling equipment, harbor and shipyard cranes, construction equipment, mobile cranes, offshore technology, tower cranes, turning machines, solar energy plants, ship deck cranes, railway crane, man lifts, wind turbines, and more. And we are proud of our designing team and our past achievements and continuous development, we are strongly motivated for the challenges to come. Adaptation to changes in the environment, we do have our own ability to customize varieties specific needs, we will do our best to provide you the most and unparalleled slewing bearing with competitive price, high quality and on-time delivery !
