The term angle of contact in the context of ball bearings refers to the angle formed between the direction of the load and a line perpendicular to the bearing axis. In the case of angular contact ball bearings, this angle is specifically designed to optimize the bearing's ability to support combined radial and axial loads, as well as pure axial loads in a specific direction.

The companies plan to invest heavily in research and development to bring the new materials to market as quickly as possible. They also plan to work closely with customers to ensure that the new materials meet their specific needs and requirements.
