The company’s aerospace and superprecision facilities produced high-performance ball
bearings and cylindrical bearings for ultra high-speed and ultra high-accuracy applications in the
aerospace, medical and dental, computer disk drive, and other industries. Those bearings utilized
ball- and straight-rolling elements and were in the superprecision end of the bearing industry. A
majority of Timken’s aerospace and superprecision products were custom-designed bearings and
spindle assemblies. They often involved specialized materials and coatings for use in
applications that subjected the bearings to extreme speed and temperature.
