Plus the choice of seal bearing the main factors should be considered

Bearing the seal can be divided into two categories own seal and the added seal. The so-called sealed bearings are the bearing comes into its own manufacturing unit with the sealing performance. Such as bearings with dust cover, seals, etc.. This sealed space is small, installation and removal easy, cost is relatively low.
    Plus the so-called bearing sealing device is installed within the end cap and other manufactured with a variety of performance seals.
    Plus the choice of the bearing seal should consider the following several main factors:
    a. types of bearings and lubricants (grease and oil);
   b. manufacturing costs.
    c. sealing the surface of the circumferential speed;
    d. bearing work environment, the size of space;
    e. axis supporting structure advantages, allowing the angle deviation;
    f. bearing operating temperature;
        Plus seal is divided into non-contact and contact of two. Are as follows:
     
    A contact seal
    Contact seal is sealed with the relative motion of parts in contact with no gap in the seal. This seal because seals and direct contact with the piece, the work of friction in the large, heat is large, could easily lead to poor lubrication, easy to wear contact surface, resulting in sealing effect and performance. Therefore, it is only suitable for medium and low speed working conditions. Contact seals are commonly used in felt seal, rubber cups sealing structure, used in different occasions.
    According to work status and working conditions bearing on the sealing requirement of engineering design is often the comprehensive use of various seal forms, in order to achieve a better seal.

B non-contact seals
    Non-contact seal that seals the relative motion of parts with no contact, and proper sealing gap. This form of seal, in the work of little friction heat, no wear, especially for high-speed and high temperature condition. Non-contact type seal commonly used with gap, labyrinth and gaskets of different structure type, and so were used in different occasions.
    Non-contact seals the gap to as small as possible is better.
