How many types does slewing bearing have?

Nowadays, a growing number of people are concerned about the development of industrial components, give that it plays an important role in different situations. Bearing is one of the most important industrial components in the world.

This report will focus on slewing bearing, and the types and characteristics will be clearly shown in the following paragraph.

What's a slewing bearing?

Slewing bearings are a kind of large bearings with a special structure that can withstand large axial load, radial load, and tilting moment at the same time. This bearing is capable of supporting, rotating, driving, and fixing a variety of functions. The large shape is the biggest feature of the turntable bearing.

Common slewing bearings are equipped with mounting holes, lubricating oil holes and sealing devices. These devices allow them to work under different working conditions. In addition, the turntable bearing itself has the features of compact structure, convenient guided rotation, simple installation and maintenance, which can greatly enhance the work efficiency.

At present, slewing bearings are widely used in engineering, mining, metallurgy, wind power, ships, ports, petroleum, chemical, light industry, medical equipment, food, vehicles, robotics, aerospace, radar, and military industries such as large slewing devices. It’s definitely an important part of contemporary industry.

What's the main structure of a slewing bearing?

Slewing bearings are usually composed of four major components such as inner ring, outer ring, rolling body, and isolation block, each of which has a key role.

The working principle is very clear, during the operation of the rotary bearing, due to the core components using slewing support, so it can bear axial force, radial force, which shows that the rotary bearing has a strong bearing capacity compared to ordinary bearings.

It is worth noting that although there are many forms of slewing bearings, the structural composition is basically similar. In other words, no matter how different the style of the turntable bearing is, it still has the same basic framework.

How many types does slewing bearing have?

As mentioned before, regardless of how different the rotor bearing styles are, the basic framework is the same. Therefore, different types of slewing bearing share the same characteristic.

The common types of slewing ring on the market are as follows, single row contact ball slewing ring, double row four-point contact ball slewing ring, three rows roller slewing ring, cross roller slewing ring, double row ball slewing ring and lightweight series slewing ring, the applications to which the different types of slewing ring respond are very different.

For example, a light slewing bearing has the same structural form as a common slewing bearing, is light in weight and has flexible rotation. It is widely used in food machinery, filling machinery, environmental protection machinery and other fields.

Finally, please check the size and type before purchasing it, which is according to your requirements.
