Slewing rings

Slewing is able to withstand the combined load bearing and can also withstand greater axial and radial load and overturning moment.
slewing ringses are also called wheel bearings, slim ball bearing  some people also call it: rotating support, maneuver support.
Slewing rings is widely used in the real industrial, known as: "the joints of the machine", is subject to the relative rotary motion between two objects, and also withstand axial, radial, overturning moment of machinery necessary for important parts.With the development of machinery industry, pivoting on ship equipment, engineering machinery, light industry, machinery, metallurgy, machinery, medical equipment, industrial machinery and other industries a wide range of applications.
Slewing bearing industry in China has gone through more than 20 years of development, since the JB2300-84 was first published in 1984 in the slewing bearing types, basic parameters and technical requirements for standard, and JB/T2300-1999 in the 1999 amendment of the slewing ring standard,  Other bearing China has been provided with a complete set of development and capacity of slewing bearings are designed, manufactured and tested.
