Thrust Ball Bearing Classification for SKF Rolling Bearings
Source: Bearing Network | Date: November 2, 2013
Thrust ball bearings are a type of rolling bearing designed to support axial loads. They are commonly used in applications where the primary load is in one or both directions along the axis of rotation. SKF, a leading manufacturer of bearings, offers several types of thrust ball bearings tailored for different operational needs. One-way thrust ball bearings are designed to handle axial loads in a single direction. These bearings typically consist of a shaft collar, a raceway, and a set of balls and cages. The design allows for easy assembly and disassembly since each component can be separated. They are often used in applications where the shaft must be fixed in one direction. However, they are not suitable for radial loads. There are also smaller versions available, such as those with flat or spherical seats, which allow for some misalignment between the housing and the shaft. Spherical seats may require additional components like spherical cushions, which can be ordered separately. Two-way thrust ball bearings, on the other hand, can support axial loads in both directions. They include two races and two sets of balls and cages, allowing the bearing to accommodate forces from either side. Like their one-way counterparts, these bearings are not designed for radial loads. They are ideal for applications where the shaft needs to be fixed in both directions. Angular contact thrust ball bearings are another type that can handle both axial and radial loads, making them suitable for high-speed applications. These bearings have a contact angle that allows them to manage combined loading conditions. They are often used in equipment requiring high stiffness and low friction, such as drilling machines or precision machinery. Cylindrical roller thrust bearings are designed for heavy axial loads and offer high rigidity while occupying minimal axial space. These bearings are typically one-way, meaning they can only support loads in a single direction. They come in single-row or double-row configurations, with the latter offering increased load capacity. The cylindrical rollers are slightly tapered at the ends to reduce edge stress and improve performance. These bearings are often used in applications where impact resistance is important. In many cases, cylindrical roller thrust bearings are sold as separate components, such as the roller and cage assembly, shaft ring, and seat. This modular approach allows for greater flexibility in installation and maintenance. Whether you're working with hydraulic excavators, industrial machinery, or other high-load applications, understanding the classification of SKF thrust ball bearings can help you choose the right solution for your needs.
