Angular Contact Ball Bearings Industry knowledge

1.What is an angular contact ball bearing?


Angular contact ball bearings are a special type of rolling bearings that are designed to withstand high axial loads. Unlike ordinary deep groove ball bearings, the angular contact ball bearing forms a fixed angle with the bearing axis, which is called the contact angle. The existence of the contact angle enables the bearing to withstand loads from different directions at the same time, especially axial loads.
The contact angle of angular contact ball bearings is usually between 15 degrees, 25 degrees or 40 degrees. The larger the contact angle, the greater the axial load the bearing can withstand, but the radial load bearing capacity will be relatively reduced. When designing, the angles of the inner and outer rings of the angular contact ball bearing are skewed so that the contact point between the ball and the inner and outer rings during rotation always remains in a stable position. This design effectively reduces friction and wear and improves the running accuracy and life of the bearing.
Angular contact ball bearings are widely used in applications that require high precision, high speed and high load. For example, in machine tool spindles, angular contact ball bearings can withstand the high axial loads generated by the spindle when it rotates at high speed while providing excellent radial support. In motors and aerospace equipment, the low friction characteristics and high stability of angular contact ball bearings are also indispensable. Due to their excellent performance, angular contact ball bearings are widely used in industry and have an extremely important position.

2. What are the main applications of angular contact ball bearings?


The main application areas of angular contact ball bearings cover multiple industries, mainly due to their ability to withstand both radial loads and high axial loads. Here are some common application scenarios:
Machine tool spindles: In machine tool spindles, angular contact ball bearings bear key load tasks. Due to the high axial loads generated by the spindle when rotating at high speeds, the high load-bearing capacity of angular contact ball bearings makes them an important part of machine tool spindles. These bearings ensure that machine tools remain stable and precise at high speeds and high loads.
Electric motors: Angular contact ball bearings in electric motors can withstand the high axial loads generated during the operation of the motor while supporting high speed operation. This allows the motor to operate efficiently while maintaining a long service life.
Aerospace: In the aerospace field, angular contact ball bearings are used in aircraft engines and control systems. Due to the extremely harsh operating environment of aerospace equipment, the high precision and high load capacity of angular contact ball bearings are key factors to ensure the reliable operation of the equipment.
Automotive industry: In the automotive industry, angular contact ball bearings are used in powertrain systems and steering systems. Their high load-bearing capacity and low friction characteristics help improve the performance and safety of automobiles.
Wind turbines: In wind turbines, angular contact ball bearings are used to support the rotation of wind turbine blades and withstand the axial load generated by wind. Their reliability and durability are crucial to the stability of wind power generation.

3. How to choose the right angular contact ball bearing?


When choosing the right angular contact ball bearing, you need to consider several key factors to ensure the best performance of the bearing in a specific application. Here are the main aspects to pay attention to when choosing:
Contact angle: The contact angle is a key factor affecting the performance of angular contact ball bearings. Depending on the size of the axial load in the application, it is crucial to choose the right contact angle. Common contact angles are 15 degrees, 25 degrees, and 40 degrees. Larger contact angles can withstand greater axial loads, but their radial load capacity is relatively low. Therefore, it is necessary to determine the most suitable contact angle based on the actual load conditions.
Bearing material: The material of angular contact ball bearings has an important impact on their performance. Commonly used materials include high carbon chromium steel, stainless steel, and ceramic materials. High carbon chromium steel has good strength and wear resistance and is suitable for general industrial applications; stainless steel has excellent corrosion resistance and is suitable for use in harsh environments; ceramic materials have extremely high hardness and wear resistance and are suitable for high load and high speed applications.
Lubrication method: Lubrication is crucial to the operation of the bearing. Angular contact ball bearings are usually lubricated with grease or oil. Grease is suitable for use under high temperature and high load conditions, while lubricating oil is suitable for use under high speed operation and low temperature environment. Choosing the right lubrication method can reduce friction and wear and extend the service life of the bearing.
Size and installation requirements: When choosing angular contact ball bearings, you also need to consider their size and installation requirements. The size of the bearing should match the design requirements of the equipment to ensure the correct installation and operation of the bearing. At the same time, the assembly accuracy of the bearing should be considered to ensure the overall performance of the equipment.
Supplier and technical support: Choosing a reliable supplier is the key to ensuring the quality of bearings. Professional suppliers such as Ningbo Sanya Bearing Co., Ltd. can provide detailed technical support and suggestions to help users choose the most suitable angular contact ball bearings. The supplier's technical support can help solve problems in installation and maintenance to ensure the best performance of the bearing.
