Precision Chrome Steel Bearing Balls from Germany
High-precision chrome steel balls used as rolling elements in ball bearings for semiconductor wafer grinders and polishers. These balls ensure smooth rotation and minimal friction during the grinding process to achieve flatness tolerances on semiconductor wafers. Classified under 8482.91.0090 as 'other' balls for bearing parts, distinct from needles or standard rollers.
