Angular contact ball bearings are designed to accommodate combined radial and axial loads while operating at high speeds. There are several types of angular contact ball bearings, each designed for specific applications and load conditions.
Single Row Angular Contact Ball Bearings: These bearings have a single row of balls with an inner and outer ring raceway. They can accommodate axial loads in one direction and radial loads. They are typically used in pairs or sets to accommodate axial loads in both directions.
Double Row Angular Contact Ball Bearings: These bearings have two rows of balls with an inner and outer ring raceway in each row. They can accommodate axial loads in both directions as well as radial loads. They provide higher radial load-carrying capacity compared to single row angular contact ball bearings.
Four-Point Contact Ball Bearings: Also known as QJ bearings, these bearings have four points of contact between the balls and the raceways. They can accommodate axial loads in both directions as well as radial loads. They are often used in applications where there are significant axial and radial loads, such as in machine tool spindles and robotics.
Thrust Angular Contact Ball Bearings: These bearings are designed to accommodate predominantly axial loads. They have raceways in the form of washers with grooved raceways for the balls. They are used in applications where high axial loads need to be supported, such as in automotive steering systems and machine tool spindles.
High-Precision Angular Contact Ball Bearings: These bearings are designed for applications that require high precision and accuracy, such as in machine tool spindles and precision instruments. They are manufactured with tighter tolerances and higher quality materials to ensure consistent performance and reliability.
Each type of angular contact ball bearing has its own advantages and is selected based on the specific requirements of the application, including load capacity, speed, precision, and operating conditions.
