      Bearing is a kind of commonly used mechanical hardware product. Good bearings need to have excellent sealing performance in the process of use. At present, the sealing of bearings can be divided into two types: self-contained sealing and external sealing. Generally, self-contained sealing is relatively simple, and the cost is relatively low. The external sealing performance device of bearings is made of sealing devices with various performance inside the installation of end covers,In order to improve the external sealing performance, some factors need to be considered in the sealing process.
    The factors to be considered for bearing external sealing are:
    1, bearing lubricant and type grease and lubricating oil;
    2The working environment of the bearing and the size of the occupied space;

   3. advantages of shaft support structure, allowable angle deviation;

   4. circumferential speed of sealing surface; 5. Working temperature of bearing; 6. Manufacturing cost 

According to the requirements of bearing working condition and working environment for sealing degree, 

various sealing forms are often used in engineering design to achieve better sealing effect.
