slewing ring bearings are nearly four decades the gradual rise

slewing ring bearings are nearly four decades the gradual rise in the world of new mechanical parts, which have inner and outer rings, rolling, etc., is a comprehensive large bearings to withstand load, can withstand large axial, radial load and tilting moment. Slewing ring in reality very broad industrial applications, known as: "the machine joint" is subject to the relative rotational movement between the two objects, and the need for simultaneous axial and radial forces, tilting moment by machinery required important transmission components. With the rapid development of the machinery industry, the slewing ring in marine equipment, engineering machinery, light machinery, metallurgical machinery (metallurgical bearing), medical equipment, industrial machinery and other industries has been widely used.
