Angular contact bearings are designed to accommodate combined radial and axial loads. There are several types of angular contact bearings, including Four Point Contact Ball Bearings and Double Row Angular Contact Bearings. Let's look at each of them:
Four Point Contact Ball Bearing: This type of bearing consists of inner and outer rings with a single row of balls positioned between them. The design allows for the bearings to withstand radial, axial, and moment loads simultaneously. The four-point contact design enables the bearing to handle both radial and axial loads in both directions. These bearings are commonly used in applications where there are significant axial loads or when the shaft needs to be supported in both radial and axial directions while allowing for some misalignment.
Double Row Angular Contact Bearing: Unlike the single row of balls in a four-point contact bearing, double row angular contact bearings have two rows of balls. These bearings are designed to accommodate higher axial loads compared to single row angular contact bearings and can also support higher radial loads. The arrangement of the balls enables these bearings to handle both axial and radial loads in both directions. They are often used in applications where there are high axial loads or where the shaft requires additional support to handle both radial and axial forces.
Both types of angular contact bearings have their advantages and are selected based on the specific requirements of the application, including load capacity, speed, and space constraints. Additionally, factors such as lubrication, sealing, and maintenance requirements also play a role in choosing the appropriate type of angular contact bearing for a given application.
