Single row angular contact ball bearings can only withstand axial load in one direction. When such bearings are subjected to pure radial load, they must be installed and used in pairs because the line of action of the rolling body load and the line of action of the radial load are not in the same radial plane, resulting in an internal axial component.
Single Row Angular Contact Ball Bearings
Single row angular contact ball bearings can only support axial loads in one direction. This type of bearing usually requires adjustment relative to another bearing. Its bearing ring has two shoulders, high and low, and cannot be separated.
Four Point Contact Ball Bearing QJ type
Four-point contact ball bearings are separable bearings that can withstand bidirectional axial loads. It belongs to radial single row angular contact ball bearing. Compared to double row bearings, the axial space occupied is significantly reduced. The contact angle of SKF four-point contact ball bearings designed by QJ is 35° or 45°. The inner ring is a flat inner ring. This allows more balls to be installed in the bearing, which can give the bearing a higher load-carrying capacity. The rotation speed of the four-point contact ball bearing is very high and the operation is very stable, and its double half-ring can be removed from the whole set of bearings and installed separately, so the four-point contact ball bearing is mainly used in the engine.
Double Row Angular Contact Ball Bearings
The double row angular contact ball bearing design is two single row angular contact ball bearings arranged back to back. This type of bearing has the same design as a single row angular contact ball bearing, but takes up less axial space. Bearings are non-separable.
Understanding Angular Contact Ball Bearings: Essential Components for Industrial Equipment
Angular contact ball bearings are pivotal components in the realm of industrial equipment, particularly in applications requiring high-speed rotation and precise motion. Unlike standard ball bearings, which accommodate radial loads, angular contact ball bearings are designed to handle both radial and axial loads simultaneously, making them indispensable for various mechanical systems.
