How to use slewing bearing effectively?

With the development of science and technology, the types of innovative materials are becoming increasing. There is no specific definition of an innovative material, it can be found in any industry. To be more precise, a brand-new category of bearing can be considered to be an innovative material.

In this article, the types and characteristics of slewing ring will be clearly indicated, and we will show you how to use slewing bearing effectively.

The types of slewing ring

The types and sizes of slewing rings can be customized according to customer requirements.

According to different characteristics, it can meet the requirements of the host machine under different load conditions. For instance, the four-point contact ball bearing has a higher dynamic load capacity, and the crossed-cylindrical roller bearing has a higher static load capacity.

In addition, common slewing bearing types include fork tapered roller bearings and three-rows of cylindrical roller combination slewing ring bearings, etc.

The characteristics of slewing bearing

Although the slewing ring has a host of categories, it still shares the same structure. Slewing bearings are composed of four major components, which are inner rings, outer rings, rolling elements, isolation blocks.

There is no doubt that slewing bearings have a number of advantages, such as high stability, high load capacity and easy installation. Moreover, there are many different types of slewing bearings, which should always be purchased or customized according to requirements before purchase.

Besides, Normal rotary table bearings are fitted with mounting holes, lubrication holes, and seals. As a result of this series of features, slewing bearings are widely used on large slewing devices such as lifting and transport machines, harbor machines, extractive machines, construction machinery, and missile launchers.

Methods for solving slewing ring noise

Slewing bearings are very durable and have a long service life. However, if they are used over a long period of time, there are problems that are difficult to avoid, such as noise problems, which are one of the biggest problems with slewing bearings.

We have listed the corresponding solutions for the different causes of the error. The first cause of the noise is the presence of foreign matter such as dust in the slewing ring, and the way to solve the problem is to improve the working efficiency. In other words, the slewing ring bearing is cleaned, and bearings, shafts, seat bores, and mating parts are all strictly cleaned before installation to avoid the use of plastic cages made of impure material or embedded with foreign objects. This will improve the sealing properties of the bearings.

Furthermore, incorrect choice of lubricant, insufficient lubricant, or the occurrence of aging hard knots can cause the slewing bearing to make noise, and this noise is not always constant. For this situation, Choose the right lubricant is the only solution, adjust the amount of lubricant, extend the service life of the lubricant, and reasonably determine the replacement cycle.

Finally, regular maintenance  is a very important part of the process. Although slewing bearings are simple to dismantle, many people neglect to carry out regular maintenance. Different types of the slewing ring have different lubricant requirements and this needs to be taken into account.
