Application of Ceramics to NU-Type Cylindrical Roller Bearings for Machine Tool Main Spindles - December 2011

Masatsugu Mori, Takuji Kobayashi

The article "Application of Ceramics to NU-Type Cylindrical Roller Bearings for Machine Tool Main Spindles" appeared in the December 2011 issue of Power Transmission Engineering.

Summary
Bearings used to support main spindles on machine tools must be capable of higher speed and greater rigidity. This is true in that any main spindle that turns together with a tool or work piece mounted onto it is one of the critical machine tool components that directly affects machining efficiency and accuracy of the machine tool; and, the bearings that support the main spindle are the most critical machine elements on the machine tool.
