Factors affecting sealing of deep groove ball bearing

The sealing performance of deep groove ball bearings is related to its service life, work efficiency and the stability and safety of the entire equipment. Let's talk in detail about several key factors that affect the sealing performance of deep groove ball bearings.

1. Seal structure design

Common bearing seal types are contact seal and non-contact seal. Contact seals are generally used to prevent external impurities from entering, while non-contact seals are more used to reduce the loss of internal lubricants. Whether the sealing design is reasonable directly determines the sealing effect.

2. Selection of sealing materials

The material of the seal also has a significant impact on the sealing performance of the bearing. Usually the material is divided into rubber seal, plastic seal and metal seal. Among them, the rubber seal has low cost but poor wear resistance, while the metal seal is resistant to high temperature but complex installation. The selection of the appropriate sealing material needs to be determined according to the working environment and specific needs of the bearing.

3. Use of lubricants

The lubricant is not only responsible for reducing friction, but also plays a sealing role to a certain extent. The use of appropriate lubricants can not only effectively improve the smoothness of bearing operation, but also prevent the entry of dust and moisture.

4. Environmental conditions

High temperature, high humidity, high dust and even high corrosive environment will seriously affect the sealing effect. Therefore, when purchasing bearings, these external conditions must be fully taken into account, and corresponding countermeasures must be made, such as the selection of high-temperature lubricants or additional dust-proof devices.

In summary, there are many factors that affect the sealing performance of deep groove ball bearings, including sealing structure design, sealing material selection, lubricant use, installation and maintenance and environmental conditions. Each factor is interlinked and cannot be ignored. May wish in practical applications, combined with the specific needs of the equipment and the working environment, multi-dimensional consideration, to achieve the best sealing performance, so that your mechanical equipment runs more stable and efficient.
