The Production Process of Angular Contact Ball Bearings and Application in Mechanical Equipment

Oct 10, 2023

Angular contact ball bearings are a common rolling bearing with the characteristics of high precision, high speed, high efficiency, etc., and are widely used in various mechanical equipment. Angular contact ball bearings will be introduced in detail below.

Structural features of angular contact ball bearings

Angular contact ball bearings have a compact structure and are mainly composed of bearing seats, outer rings, inner rings, steel balls, and cages. The bearing seat is one of the important components of angular contact ball bearings. It not only provides support for the bearing but also affects the accuracy and stability of the bearing. The outer ring and inner ring are the outer and inner rolling element tracks of the angular contact ball bearing, respectively. The steel balls and cage keep the rolling elements in the correct position and evenly distributed.

Angular contact ball bearings find extensive application in a range of mechanical equipment. The following are some application examples of angular contact ball bearings:

Single-row angular contact ball bearings: can be used in machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, small car front wheels, differential pinion shafts, etc.

Double row angular contact ball bearings: This bearing can be used in oil pumps, Roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery, etc.

Aligning ball bearings: can be used in woodworking machinery, textile machinery drive shafts, vertical seated self-aligning bearings, etc.

In addition, angular contact ball bearings are also used in endoscopic systems of medical devices, aerospace, thermal power plants, and other fields.

How to select angular contact ball bearings?

When selecting angular contact ball bearings, comprehensive considerations need to be made based on the actual working conditions and usage environment.

Working speed: The speed of angular contact ball bearings is relatively high, generally reaching several thousand rpm or even higher. When selecting angular contact ball bearings, the impact of operating speed on bearing performance needs to be considered. Generally speaking, the higher the precision and the faster the rotation speed, the higher the price of the bearing.

Load-carrying capacity: The load-carrying capacity of angular contact ball bearings depends on factors such as their structural size, material, accuracy level, etc. When selecting angular contact ball bearings, the selection needs to be based on the actual working load to ensure that the bearing has sufficient load-bearing capacity.

Installation method: The installation method of angular contact ball bearings has a great impact on the performance and service life of the bearing. When selecting angular contact ball bearings, you need to choose according to the actual installation method to ensure that the ball bearing is installed correctly, stably, and reliably.

Precautions for using angular contact ball bearings

When using angular contact ball bearings, you need to pay attention to the following points:

Lubricant selection: Lubricant is one of the important factors affecting the performance and service life of angular contact ball bearings. When selecting lubricants, you need to choose according to the actual working conditions and usage environment to ensure that the type and amount of lubricant are appropriate.

Assembly accuracy: The assembly accuracy of angular contact ball bearings has a great impact on their performance and service life. When assembling angular contact ball bearings, professional equipment and technology are required to ensure that the assembly accuracy meets the requirements.

Sealing performance: The sealing performance of angular contact ball bearings has a great impact on its performance and service life. When using angular contact ball bearings, you need to pay attention to maintaining good sealing performance of the bearing to prevent water, dust, and other impurities from entering the inside of the bearing.

In short, when using angular contact ball bearings, you need to pay attention to assembly accuracy, lubricant selection, sealing performance, and other factors to ensure their normal operation and extend their service life. Also, choose the best angular contact ball bearing supplier.

What is the manufacturing process of angular contact ball bearings?

The manufacturing process of angular contact ball bearings can be divided into the following steps:

Select raw materials: According to the specifications and performance requirements of the bearing, select appropriate raw materials or blank forms, such as bars, wires, etc.

Turning: Turn the blank to process the inner and outer rings of the bearing.

Heat treatment: Heat treatment is performed on the inner and outer rings of the bearing after turning to improve the mechanical properties and hardness of the material.

Grinding: Grind the heat-treated inner and outer rings of the bearing to obtain higher dimensional accuracy and surface roughness.

Grinding or polishing: Grind or polish the inner and outer rings ground of the bearing to obtain a smoother surface and lower surface roughness.

Final inspection of parts: Conduct a final inspection of the processed bearings to ensure that they meet the design requirements and quality standards.

Anti-rust: Perform anti-rust treatment on qualified bearings to extend their service life and prevent rust.

Storage: Put the anti-rust bearings into storage, waiting for assembly and use.

It should be noted that the above are only general steps for manufacturing angular contact ball bearings. Actual production may vary due to different specifications, materials, and process requirements. At the same time, attention needs to be paid to quality control and environmental protection during the production process to ensure the bearing quality and reliability.
