The mill rotor bearings, which are mounted in a steel housing, are two (2) cylindrical roller bearings, NU 316 ECM/C3, and one (1) grooved ball bearing, SKF 6316 C3. The bearings have failed several times over a period of two (2) years. Before this time, the mill had no recorded bearing failures (as confirmed by the CMMS).

Bearing rings and balls are not perfectly round and the balls and raceways, even after extensive fine grinding and polishing, are not perfectly smooth. There are machining imperfections in the form of rough or uneven surfaces which will cause one ring to move or oscillate radially in relation to the other causing bearing vibration and noise.

• bearings withstand static misalignment of the shaft of +/− 3 degrees. • Designed for normal operation between −20° C and 100° C. • Wide inner ring ball bearings deliver greater shaft support. • high-strength housings are suited for most industrial applications. • bearings are prelubricated and ready for immediate installation.

2.1 Machining ball rolling elements. In the grinding process of balls, the balls are placed on a cast iron plate with grooves parallel to the grinding wheel. The process takes place over several stages which can be grouped into two overarching phases: rough grinding and finish or lapping operations. 2.1.1 Rough grinding.
