  • High Speed Bearings for Machine Tool Spindles |

    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 assembly, that leads to uncontrolled hertzian stresses …

    1994-9-15 · The example in the diagram, figure 6, shows a comparison of bearings for a high speed internal grinding spindle. At a speed of 40,000 r/min the radial stiffness of a particular hybrid bearing has been reduced to 70 % of the static stiffness, while for a comparable bearing with steel balls the stiffness has been reduced to 61 %.

    2019-4-1 · To lubricate bearings to achieve ultra-high-speed revolution, we adopted air-oil lubrication, in which air is used with a small amount of oil. Using the minimum necessary oil along with air and accurately supplying it to the boundary between the ball and the race provides sufficient lubrication while preventing the temperature from rising.
