What is a thin-walled bearing seal?

There are corresponding sealing devices installed on both ends of the bearing, but many people dont know what the sealing device does? Lets take a look at the role of the sealing device for thin-walled bearings.

1. Keep the grease (oil) inside the bearing from being lost during use to ensure that the bearing is in a lubricated state;

2. Protect the dust or harmful gases outside the bearing from entering the inner cavity of the bearing to prevent damage to the bearing.

The sealing structure of the sealing ring is diverse, so the sealing effect is also different. There is a gap between the sealing ring and the rotating shaft, which is called a non-contact seal. The smaller the gap, the better the sealing effect, but the smaller the allowable shaft speed; the opposite is true. There is no gap between the sealing ring and the rotating shaft, which is called a contact seal. The larger the contact area of the sealing ring contact lip, the better the sealing effect, but the smaller the allowable shaft speed, and the opposite is true. The main research content of sealing technology is to research and develop corresponding sealing devices for different working conditions, as well as the compatibility of the sealing ring material and the corresponding grease.
