slewing bearings can be divided into the following types according to their structures as single row four point contact ball slewing bearing, single row cross roller slewing bearing, double row different ball diameter slewing bearing, three row cylindrical roller slewing bearing and roller/ball combination slewing bearing. 

  • slewing bearings can be divided into the following types according to their structures as single row four point contact ball slewing bearing, single row cross roller slewing bearing, double row different ball diameter slewing bearing, three row cylindrical roller slewing bearing and roller/ball combination slewing bearing. 

    These types of bearings can be further divided into bearings without gears, bearings with external gears and bearings with internal gears.

    This kind of bearings has high load carrying capacity. Under same loads, this kind of bearings has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers.Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials-handling, offshore technology and general mechanical engineering etc.
