Why do bearings use seals?

What is the basic concept of bearing life?
It is mainly based on the number of possible completions after a bearing shows symptoms at the beginning (for example, peeling or cracking due to wear).
What are bearings and their types?
Bearings are mechanical components consisting of rolling elements and inner and outer rings that are usually used in rotary or linear shaft applications. There are several different types of bearings, including bearings and roller bearings, linear measurement, and possibly rolling.

Why do motors need bearings?
The purpose of the bearing in the motor is to support and position the bracket, keep the air gap small and convenient, and facilitate the movement of the load from the shaft. The bearing should be able to run at low and high speeds while sliding to reduce friction losses.

High speed vacuum cleaner?
Contact angular contact thrust ball bearings for ceramic balls can also significantly increase speed/temperature.

The effect of sunlight device on thin-walled bearings
Install their own sealing devices on the supporting end faces, but many people don’t know what the sealing devices do? Let's take a look at what effect the sealing device has on thin-walled bearings.
1. The grease (oil) inside the bearing remains unchanged during use to ensure that the bearing remains lubricated;
2. Protect the baby's dust or odor from entering the inner cavity of the bearing to prevent injury.
The sealing structure of the sealing ring is consumer's, so the sealing effect is also different. If there is a gap between the sealing ring and the rotating shaft, non-contact sealing, the smaller the gap, the smaller the sealing effect, but the shaft is allowed to pass; the opposite is true. If there is no gap between the sealing ring and the rotating shaft, it is called a contact seal. The contact hug of the contact lip of the sealing ring, the sealing effect is visible, but the shaft is allowed to be small, and vice versa. The research content is to research and develop the corresponding sealing device under different working conditions in deep water, as well as the melting property of the sealing ring material and the corresponding grease.
