  • What is slewing bearing with external gear


    The external gear slewing bearing is a slewing bearing with external teeth. It is a new type of mechanical component. It consists of inner and outer rings, rolling elements and so on, and has external gears on the outside of the bearing. The slewing bearing with external gear is a large bearing capable of withstanding the combined load and can withstand large axial, radial loads and overturning moments at the same time. Read More

  • What is flange slewing bearing


    Slewing bearing is also called turntable bearing, some people also call it: rotating support, gyro support. Slewing support is widely used in the real industry. It is called "the joint of machine". It is an important transmission part of the machinery that needs to rotate relative motion between two objects and bear axial force, radial force and overturning moment at the same time. With the rapid development of machinery industry, slewing support has been widely used in marine equipment, construction machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries. Rotary bearings are mainly divided into light rotary bearings, flange slewing bearings, single row ball rotary bearings, four-point contact ball bearings and other rotary bearings with different structures and functions. Below we introduce the flange slewing bearing, as well as its application and function. Read More

  • Single Row Ball Slewing Bearing Vs Single Row Crossed Roller Slewing Bearing


    There are many types of slewing bearings as "mechanical joints", such as single row ball slewing bearings and single row crossed roller slewing bearings. Since these two kinds of slewing bearings belong to the single row support, many people can't distinguish the two kinds of differences, and they can be randomly selected and used without knowing, which will cause great damage to the machine. This article will help you understand the information about these two slewing bearings. Read More

  • Four point contact ball bearing vs single row ball slewing bearing


    How to choose four point contact ball bearings and single row rotary bearings correctly may be a challenge for many people, especially when there are strict technical, reliability or economic requirements. In these cases, our company can use state-of-the-art analytical methods to provide advanced calculations and simulations to optimize and validate the best design to meet customer needs. Our company has a variety of customized bearings that meet design standards and different diameters to meet the needs of special applications. This paper briefly analyses four point contact ball bearings and single row rotary bearings as well as their characteristics. I hope this article will be helpful to you. Read More

  • Four Point Contact Ball Bearing Design


    With the development of society, more and more machinery has been put into use, bringing great convenience to people's lives. The bearing is an important component in contemporary mechanical equipment. It is used to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The four point contact ball bearing is one of the bearings. This article aims to describe its unique design. Read More

  • Application of four point contact ball bearing


    The four-point contact ball bearing is a radial single row angular contact ball. Slewing bearings have raceways designed to handle two-way axial loads. These bearings require minimal space and can withstand both pure axial loads and combined loads. These bearings are used in a variety of industries to provide greater precision and safety. This paper also analyzes the ball motion and sliding friction in the bearing, which can understand the bearing more concisely. Read More
