    1. Understanding Angular Contact Ball Bearings (approximately 200 words)

    Angular contact ball bearings are specialized types of ball bearings designed to handle combined radial and axial loads simultaneously. Unlike radial ball bearings, which primarily support radial forces, angular contact ball bearings are capable of withstanding both axial and radial forces due to their specific design features.

    These bearings consist of inner and outer rings with a cage containing a set of balls. The inner race is typically mounted on a shaft, while the outer race remains stationary. The balls are arranged in a contact angle, usually between 15 and 40 degrees, allowing them to transmit both radial and axial loads efficiently. The contact angle determines the bearing's load capacity and the ability to withstand thrust forces.
