What are the arrangements of angular contact ball bearings?

An angular contact bearing arrangement refers to the configuration of angular contact bearings within a mechanical system. Angular contact bearings are designed to accommodate combined radial and axial loads by enabling angular movement between the inner and outer races. This arrangement allows for efficient transmission of both radial and axial forces, making angular contact bearings suitable for applications where high precision and load-carrying capacity are required.

There are several common configurations for angular contact bearing arrangements, each suited for specific applications and load conditions:

Single-Row Angular Contact Bearings

In this arrangement, a single angular contact bearing is used to support both radial and axial loads. The inner and outer races have a contact angle, typically between 15 and 40 degrees, which allows the bearing to carry axial loads in one direction while still accommodating radial loads. Single-row angular contact bearings are commonly used in applications such as machine tools, pumps, and gearboxes.

Double-Row Angular Contact Bearings

Double-row angular contact bearings consist of two rows of balls and raceways, arranged back-to-back or face-to-face. This arrangement enables the bearing to support higher axial loads and moment loads compared to single-row bearings. Double-row angular contact bearings are commonly used in applications such as automotive wheel hubs, conveyor systems, and agricultural machinery.

Tandem Arrangement

In a tandem arrangement, two single-row angular contact bearings are mounted in series, with one bearing positioned behind the other along the shaft axis. This configuration allows for increased axial stiffness and load-carrying capacity, particularly in applications with heavy axial loads or alternating axial loads in both directions.
