Slewing Ring is a large-sized bearing with special structure which can sustain the compresive heavy loadings, like radial loading, axial loading and tangible moment. In the most cases, because of its mounting holes, grease holes and sealing device, they can fullfill the different requirements of any main frame in all kinds of working conditions. In other hands, slewing bearing which have the characteristic of cramped construction,, convenient rotary guide, handy installation and easy maintain are widely used in elevating machinery, harbor machinery, mining machinery, constructional engineering machinery, missile launcher and other large-sized rotators。
