Precision ball bearings are used for high precision applications in a variety of markets, including aerospace, health, machine tool, robotics and general industry.Ball bearings with shields or seals for protection can be lubricated to last for the operating life. Sometimes ball bearings are also called “deep groove ball bearings.

Precision balls are used in critical aeronautical bearings, guidance system balls for space and military applications, precision valves, automotive bearings and other applications where higher precision is necessary. Precision balls are defined by grade: The lower the number of the grade, the more precision to which the ball is manufactured.
