Double-row ball slewing bearingFour point contact ball slewing bearing Cross roller slewing bearing Three-row roller slewing bearing Ball and roller combination slewing bearingFour point contact ball slewing ring application in excavator is one of important load supporting parts on a excavator. It is connected with slewing table weldment of complex structure and loads. With finite element method as a tool, a model of finite element calculation is set up for Four point slewing ring of excavator and structural strength and rigidity analysis are conducted on it.

SKF Single row deep groove ball bearings are used in a wide variety of applications, they are simple in design, non-separable, suitable for high speeds and are robust in operation, and need little maintenance. Deep raceway grooves and the close conformity between the raceway grooves and the balls enable deep groove ball bearings to accommodate axial loads in both directions, in addition to radial loads.

XZWD engineers apply their experience and expertise to create a wide variety of solutions to address the most unique bearing challenges, making wanda leading supplier of excavator bearings.

The Single row ball slewing ring bearing feature two fittings for lubrication, spaced 180° apart. Geared races have tapped holes, while non-geared races have through holes. All have integral seals designed to protect against contamination.

Rotary support, also known as turntable bearings, some people also called it: rotation support, swing support.English name are: slewing bearing, slewing ring bearing, turntable bearing, slewing ringRotary support in the real industry is widely used, is known as: "machine joints", between the two objects need to be relative to the rotary motion, but also need to bear axial force, radial force, tipping moment of the machinery Essential transmission parts necessary. With the rapid development of machinery industry, slewing support in the ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries have been widely used.

The quality and the precision of our manufacturing is the key to ensure good running after many dismantling operations of the excavator. Our slew bearings are supplied for ship loaders to load and un-load various commodities.

Slewing bearings are a large bearing capable of withstanding integrated loads and can withstand large axial, radial and overturning moments.

Single row deep groove ball bearings are manufactured as open type (unsealed), sealed and shielded, the most popular sizes of deep groove ball bearings are also produced in sealed versions with shields or contact seals on one or both sides, the bearings with shields or seals on both sides are lubricated for life and are maintenance free. A sealed bearings seals has contact on the bearings inner and outer, a shielded bearings shield has contact on the outer only, and Shielded bearings are primarily intended for applications where the inner ring rotates. If the outer ring rotates, there is a risk that the grease will leak from the bearing at high speeds.
