Basic Structure and Structural Characteristics of Angular Contact Ball Bearings

Angular Contact Ball Bearing

Basic Structure

Angular contact ball bearings are a common type of rolling bearings. Their basic structure includes inner ring, outer ring, steel ball, cage and seal (optional). Below is a detailed description of each component:

Inner Ring: It is usually cylindrical and installed on the shaft. The raceway on the inner ring is used to accommodate the steel balls.

Outer Ring: It is usually cylindrical and installed inside the outer bearing housing. The raceway on the outer ring is used to accommodate the steel balls.

Steel Balls: These steel balls are located between the inner and outer rings. They roll on the raceways and support the load of the bearing.

Cage: The cage is the component used to maintain the position of the steel balls and ensure that they are evenly distributed. It can be made of different materials such as metal or plastic.

Seals (optional): Some angular contact ball bearings have seals to prevent dust, dirt, and fluids from entering the inside of the bearing, thereby increasing the life of the bearing.

Structural Features

Angular contact ball bearings have some notable construction features that give them advantages in specific applications:

Angular Contact: The design of angular contact ball bearings allows them to carry both radial and axial loads, making them useful when carrying loads from multiple directions simultaneously.

High Stiffness: Due to the contact angle between the ball and the raceway, angular contact ball bearings usually have high stiffness and can provide stable support, especially at high speeds.

High Accuracy: Angular contact ball bearings generally have high accuracy and are suitable for applications requiring precise position control, such as machine tools and precision instruments.

Various Sizes and Series: Angular contact ball bearings are available in different sizes and series to suit the needs of various applications.

Separated Structure: Some angular contact ball bearings adopt a separated inner and outer ring structure to facilitate installation and maintenance.

High-speed Resistance: Due to their design and high stiffness, angular contact ball bearings are suitable for high-speed rotational applications.

High Temperature Resistance: Some angular contact ball bearings use special materials and lubricants to improve high temperature resistance.

In summary, angular contact ball bearings are a multifunctional bearing type whose unique structure and characteristics make them suitable for a variety of industrial applications, including machine tools, automobiles, wind turbines, aerospace and other fields. It can simultaneously withstand multi-directional loads and high stiffness, which makes it ideal choice for high-performance applications.
