Machine Tool Spindle Ball Bearings - Alpine Bearing

Ball Bearing Description. Ceramic balls are 50% lighter than steel balls, and because they are almost perfectly smooth, they exhibit vibration levels 2-7 times lower than conventional steel ball bearings. These bearings also run at significantly lower operating temperatures, and allow running speeds to increase by as much as 25%.

High Speed Bearings for Machine Tool Spindles - ScienceDirect

A major car manufacturer reports that the greatest part of machines down time is due to spindle bearings failure, despite the fact that their loads are generally very low. It is Shown in this paper that the main reason for these early failures is thermal instability of the bearings/spindle/spindle housing assely, that leads to uncontrolled hertzian stresses and hence to bearing destruction.
