The selection of bearing models needs to consider the following factors:

1. Bearing carrying capacity: Select the appropriate bearing carrying capacity according to the required load.

2. Bearing speed: select the appropriate bearing speed according to the equipment speed and working conditions.

3. Environment and manufacturing materials: According to the requirements of the use environment and manufacturing materials, select bearings with characteristics such as corrosion resistance, wear resistance, and tensile resistance.

4. Installation method and adjustment requirements: According to the equipment installation method and adjustment requirements, choose different types of bearings such as self-alignment and adjustable bearings.

5. Maintenance and maintenance: According to the maintenance and maintenance requirements of the bearings, choose bearings that are easy to maintain and clean.When making bearing

 selection, the following judgment criteria can be used:

1. Specification: According to the standard size required by the equipment, select the bearing specification that meets the requirements.

2. Quality: Choose brand bearings with good reputation and quality assurance to ensure their service life and quality.

3. Applicability: Select the applicable bearing type according to the operating environment and working conditions of the equipment.

4. Reliability: Choose a tested and verified bearing model to ensure its reliability and safety.

In short, selecting the appropriate bearing type requires comprehensive consideration of various factors to ensure the normal operation and high-efficiency performance of the equipment.
