The structure and components of a tapered roller bearing usually include the following important elements:
Inner Ring: The inner ring is the internal ring of a bearing, usually mounted on a rotating shaft. It has a cylindrical or tapered outer surface, which is used to make contact with the rollers and transmit the load. The inner ring usually has bearing mounting holes, oil grooves and oil holes .
Outer Ring: The outer ring is the outer ring of the bearing, usually mounted in the bearings seats or inside the shell. It has a cylindrical or conical inner surface that is compatible with the inner ring, and is also used to contact with the rollers and transfer the load. The outer ring usually has fixed screw holes, sealing device mounting seat, bearing seat and other features.
Rollers: Rollers are the main rolling elements of tapered roller bearings, they are located between the inner and outer rings and are responsible for bearing and transferring loads. These rollers usually have a conical shape, so they are called tapered rollers. The number, size and arrangement of the rollers will vary depending on the size and design of the bearing.
Cage: A cage is used to maintain the spacing of the rollers, ensuring that they are evenly distributed between the inner and outer rings. Cages can be made of metal or plastic and are designed to help minimize friction and maintain the correct position of the rollers.
Seals: Some tapered roller bearings may be equipped with seals to prevent the ingress of dust, contaminants and lubricants while maintaining lubrication inside the bearing. Seals can be rubber seals or metal sealing cover.
Lubricant: Tapered roller bearings require a proper lubricant to minimize friction, cool bearing components and extend the lifespan. The lubricant, usually bearing grease or oil, is distributed to the rolling surfaces through grooves and holes in the bearing.
These components work together synergistic-ally to enable tapered roller bearings to withstand and transmit a wide range of radial and axial loads to support the motion of rotating shafts. Their construction and design vary according to different application requirements and bearing specifications.
WEEYH is jointly formed by China's top agricultural machinery parts factories, focusing on the R&D and production of agricultural machinery parts. About 200,000 sets of agricultural machinery related parts are produced by WEEYH'S factories and sent to the world every year.
