Sealing device has two main function:
① to prevent the outside dirt, such as metal particles, dust, dirt, moisture, sour gas and others;
② to prevent the lubricant inside the bearing overflow, in order to ensure good lubrication.

If the seal is poor, spherical roller bearings conditions will be deteriorated, greatly reducing its service life.

If the lubricants leakage, not only waste oil, pollute the environment, but also spherical roller bearings will burn out because of the lack of oil;
Intrusion of hard dirt outside can cause indentation on the rolling surface, and reducing spherical roller bearings working life.Outside the corrosive medium intrusion, spherical roller bearings will rust, resulting in bearing failure.

So bearing seal is very important,if you want to learn more about sealed spherical roller bearings, please feel free to contact us.
