| Abstract | Low temperature-rise is an important technology in bearings for machine tool main spindles. Bearings with low temperature-rise enable energy saving by reducing power consumption cooling system for machine tools. This is effective in improving machining accuracy as it reduces thermal extension. It is also effective in improving machining effi ciency as it increases the high-speed capability of the spindle. Although we are creating a lineup of the angular contact ball bearing and cylindrical roller bearing, which had low temperature-rise and were excellent in high velocity rotation performance when used by machine tool main spindles, we would like to incorporate further low temperature rise technology in order to improve product appeal. |
