Overview of Sealed spherical roller bearing

wallpapers News 2021-07-22
The sealed spherical roller bearing includes an inner ring and an outer ring. A cage is arranged between the inner ring and the outer ring. Rollers are arranged on both sides of the cage between the inner ring and the outer ring. It is characterized by the inner ring and the outer ring. There are end caps for sealing the inner end of the bearing on both end faces of the ring. The sealed end cover can effectively protect the internal structure of the bearing from external aggressions, prolong the service life of the bearing, and enable the bearing to run for a long time under complex environmental conditions such as high temperature, high pressure, and heavy load.
 
Spherical roller bearings are universally applicable to various machines. The ordinary roller bearing generally includes an inner ring and an outer ring. A cage is arranged between the inner ring and the outer ring. Both sides of the cage are evenly distributed with axial pockets, and the pockets on both sides are arranged in a cross shape. There are rollers in each pocket, and the rollers are drum-shaped spherical rollers. The inner surface of the outer ring and the corresponding inner ring raceway of the roller are both spherical. A circumferential boss is processed in the middle of the inner surface of the cage, and the inner surface of the circumferential boss and the inner surface of the inner ring are in a contact-like sliding fit, and the inner ring guides the movement of the cage.
 
However, because spherical rollers are generally used in harsh working conditions, if this ordinary spherical roller bearing is directly installed in the above environment, the inside of the bearing is easily contaminated, which greatly reduces the life of the bearing and affects the equipment. Normal operation.
 
Sealed spherical roller bearings can be widely used in places with relatively harsh environments, such as steel metallurgy, mining, petrochemical, papermaking, cement manufacturing, and other engineering machinery fields. Sealed end caps are provided to effectively protect The internal structure of the bearing is protected from external aggressions, which prolongs the service life of the bearing and enables the bearing to run for a long time under complicated conditions such as high temperature, high pressure, and heavy load.
