Slewing Ring Bearing

• Slewing bearing has four series: Four point contact ball bearings without teeth, outer teeth and inner teeth, double row angle contact ball bearing, cross cylindrical roller bearing, cross taper bearing and three row cylindrical roller compound bearing.
• Four point contact ball bearings have higher static load capacity.
• Cross cylinder roller bearing has high dynamic load capacity, the pre - interference of cross taper roller bearing can make the bearing more rigid and accurate.
• Three rows of cylindrical roller combination bearing due to the increasing of bearing height capacity , a variety of forces are borne by different raceway, so the same force, the diameter of the bearing can be greatly reduced, so that the main engine more compact is a kind of slewing bearing with high capacity.

Our four point contact ball slewing bearing is made up of two seat rings. In this slewing bearing, the balls contact with the circular raceway at four points. The bearing can support axial force, radial force and resultant moment simultaneously.

Our four point contact ball slewing bearings are compact in design and light in weight. They can be applied in slewing conveyors, welding manipulators, middle or small sized cranes and excavators, etc.

Feature

Rotary bearing is widely used in the real industrial , known as: "the joint of machine", its main applications are widely used in: autocranes, rail cranes, port cranes, ships cranes, metallurgical cranes, container cranes, excavators, filling machine, and CT machine standing wave therapy apparatus, navigation, radar antenna tower, missile launcher, tanks and robots, and revolving restaurant, etc.

Slewing bearings are large-sized bearings which can accommodate a combined load, i.e., radial loads and tilting moment. They are usually provided with holes for fixing bolts; internal, external or no gear; and lubrication holes and seals, which allow a compact and economical arrangement. In addition, they often enable the elimination of many components necessary in the classical bearing arrangement.
