How to choose the right bearing you want

 

 

 

Abstract:

Bearings play a vital role in various mechanical engineering. Choosing the correct bearing can not only improve the operating efficiency of the equipment, but also extend the service life of the equipment. Therefore, it is extremely important to have a thorough understanding of the bearing selection principles and processes. This article will discuss in detail the key factors and steps for bearing selection.

Key factors in bearing selection

1. Load size and type

Bearing selection must first consider the size and type of load. This includes radial loads, axial loads and combined loads. For large loads and impact loads, bearings with higher load-bearing capacity need to be selected, such as cylindrical roller bearings or tapered roller bearings. For small loads, you can choose deep groove ball bearings or angular contact ball bearings.

2. Speed

The speed of the bearing is also an important selection factor. Generally speaking, the higher the speed, the higher precision the bearings need to be selected. For equipment running at high speeds, deep groove ball bearings or angular contact ball bearings are usually chosen.

3. Temperature conditions

The temperature of the working environment also affects the selection of bearings. For high temperature environments, you need to choose bearings that can withstand high temperatures, such as high temperature bearings. For low temperature environments, it is necessary to choose bearings with good low temperature performance, such as low temperature bearings.

4. Environmental conditions

Environmental conditions, including pollution levels, humidity, corrosiveness, can affect bearing selection. For environments with serious pollution, it is necessary to choose bearings with good sealing performance. For environments with high humidity or corrosiveness, bearings with anti-corrosion properties can be selected.

Steps of bearing selection

1. Determine load and speed conditions

First, it is necessary to accurately determine the load and speed conditions that the bearing needs to withstand. This includes the radial load, axial load and combined load that the bearing needs to bear during the operation of the equipment, as well as the operating speed of the equipment.

2. Select bearing type

Depending on the load and speed conditions, the type of bearing can be determined. For example, for large loads and impact loads, you can choose cylindrical roller bearings or tapered roller bearings. For equipment running at high speeds, you can choose deep groove ball bearings or angular contact ball bearings.

3. Determine bearing size

Determine the size of the bearing based on the design and space conditions of the equipment. This includes the bearing’s inner diameter, outer diameter, and width.

4. Select bearing material and sealing form

Select the appropriate bearing material and sealing form according to the temperature, pollution level, humidity and other conditions of the working environment. For example, for high temperature environments, high temperature bearing materials can be selected. For severely polluted environments, bearings with good sealing performance can be selected.

5. Check calculation

Finally, based on the basic rated life of the bearing and the service life requirements of the equipment, a check calculation is performed to ensure that the selected bearing can meet the use requirements of the equipment.

Bearing selection is a complex and important process that requires consideration of many factors, including load, speed, temperature and environment. Only correct selection can ensure the excellent performance of the bearing in the equipment, improve the operating efficiency of the equipment, and extend the service life of the equipment.
