Internal Gear Tooth Quenched Single Row Ball Slewing Ring Bearing From Excavator

Internal gear tooth quenched single row ball slewing ring bearing from excavator 

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

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 ring
Rotary 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 following slewing we can supply:

Double-row ball slewing bearing
Four 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.

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.

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.

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.
