Precision 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.

With high running accuracy, high-speed performance and high system rigidity, super-precision bearings are ideal for machine tools and other precision applications such as rolling mills, racing cars and marine vessels. The bearings also minimize noise, vibration and heat generation.
