What function does the external sealing device of the bearing play?

Prevent external impurities from entering: During the operation of bearings, they may be affected by dust, moisture, foreign objects, etc. in the external environment. If these impurities enter the interior of the bearing, it may cause damage to the bearing or prevent it from operating normally. The external sealing device can effectively prevent these external impurities from entering the interior of the bearing and protect the bearing from damage by the external environment.

Prevent lubricant leakage: When bearings are in operation, lubricants are needed to reduce friction and wear and improve operational efficiency. However, if the sealing performance of the bearing is poor, the lubricant may leak out, which not only affects the lubrication effect of the bearing but also may cause environmental pollution and safety issues. The external sealing device can ensure the sealing performance of the bearing and prevent the leakage of the lubricant.
