What are the operating principles of slewing bearing

Slewing bearing, a large bearing capacity of bearing combined loads, can simultaneously withstand large axial and radial loads and overturning moments. Some people also call it: rotary bearing, gyratory bearing. Cheap slewing bearing and general slewing bearing generally come with mounting holes, inner or outer gears, lubricating oil holes, and sealing devices, thus enabling the host design to be compact, easy to guide, and easy to maintain. Do you know how they work?

What is a slewing bearing

Slewing bearing is a kind of extra-large bearing that can bear the comprehensive load because its shape is similar to a plate, it is also called "rotary bearing", which can simultaneously bear large axial load, radial load, and tilting moment, and can replace several sets of common bearings used in combination. Large slewing bearings are generally used in machinery and equipment that can withstand huge overturning moments and make relative rotational movements and are a kind of combined bearings with high efficiency and high load-bearing capacity. Only by taking care of the large slewing bearing, we can ensure the efficiency and productivity of the machine.

Characteristics of the slewing bearing

Slewing bearings have mounting holes, internal or external gears, lubricating oil holes, and sealing devices, with a compact structure, accurate and smooth transmission, flexible rotation, long service life, easy installation, and easy maintenance of daily use, and other characteristics. For different use requirements, slewing bearings have a variety of structural types to adapt to it, and can be manufactured with different levels of precision to meet the needs of the host function, and therefore can be widely used in lifting machinery, construction machinery, metallurgical machinery, medical machinery, etc., is a mechanical rotary device on the indispensable machine parts.

Working Principle

Point contact rolling working principle is mainly used for four-point contact ball slewing bearing and cross roller slewing bearing. This working principle for point contact radial-axial force combination to bear the steel ball quality requirements are high, and the track to angle uniform. Face contact rolling combined working principle. The working principle is mainly used for three rows of roller slewing bearing, its advantage is the contact surface is large, bearing force uniform rolling flexible. The main roller-slip combined rolling working principle is mainly used for ball column combined slewing bearing, the eccentricity of this principle is small, long life, with the advantages of roller and ball double structure. Customers can choose according to their needs. Choose the product that suits your needs.

The above is about the working principle of the product. Because of the wide range of applications of slewing bearings, they are now favored by the majority of people in demand.
