The Working Principle of Slewing Ring

China slewing ring bearing is a kind of extra-large bearing that can withstand comprehensive loads. Since its shape resembles a plate, it is also called "turntable bearing". It can not only bear large axial load, radial load and overturning moment at the same time, but also can replace the combined use of several sets of ordinary bearings. It is generally suitable for mechanical equipment that bears huge overturning moment and makes relative rotational movement. It is a combined bearing with high efficiency and high load carrying capacity.


China slewing ring bearing generally have a diameter of 0.4 to 10 meters, with mounting holes, internal or external gears, lubricating oil holes and sealing devices. It has the characteristics of compact structure, accurate and stable transmission, flexible rotation, long service life, easy installation and convenient daily maintenance; For different use requirements, the slewing bearing has a variety of structural types to adapt to them, and can meet the needs of the main engine with different manufacturing accuracy levels. Therefore, it can be widely used in hoisting machinery, construction machinery, metallurgical machinery, medical machinery, transportation machinery, food machinery, textile machinery, material processing machinery, military equipment, aerospace equipment, power generation equipment and other fields. It is an indispensable machine part of a mechanical slewing device.


The slewing ring is a very versatile mechanical basic part which is composed of two ferrules, a set of rolling elements and a holder. According to actual usage and design structure, there are different working methods. There are two basic working methods: 

1. The inner ring fixes its supporting function and the outer ring rotates. 

2. The outer ring fixes its supporting function and the inner ring rotates.
