High accuracy: Precision balls are manufactured to strict tolerances in diameter, roundness, and surface finish.

Grades: Defined by numerical grades (e.g., Grade 3 to Grade 50). The lower the grade number, the higher the precision. For example, Grade 50 is considered precision, while Grade 100 is semi-precision

Materials: Commonly made from stainless steel, chrome steel, ceramics, or plastics depending on the application
