slewing drive application

Slewing drives function with standard worm technology, in which the worm on the horizontal shaft acts as the slewing drive for the gear. The rotation of the horizontal screw turns a gear about an axis perpendicular to the screw axis. This combination reduces the speed of the driven member and also m

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.

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.

Dual axis slew drive application

The dual axis slew drive is a new type of rotary product, usually called a slewing bearing, which is usually composed of a worm, a slewing ring, a case, a motor and the like. Since the core components are slewing bearings, they can simultaneously withstand axial forces, radial forces, and tipping moments. Compared with the traditional rotary products, the dual axis slew drive has the characteristics of simple installation, easy maintenance and more installation space saving. Slewing drives are mainly used in aerospace, tower cranes, excavators, construction machinery, conveyor machinery, elevators, aerial work, satellite receiving systems, solar tracking systems and many other industries.

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.
