Precision Machine Tool Bearings Precision Machine Tool Bearings With over 20 years of experience in the machine tool spindle service market, SPS Spindle has an extensive amount of technical experience in precision machine tool bearings, and bearing applications.Precision Angular Contact Ball Bearings are also known as machine tool & spindle bearings. These 15° contact angle bearings are manufactured to supe dimensional tolerance standards and can handle very high speeds.

Precision angular contact ball bearings for spindles and lead screws are the basic components of machine tools. Their performance directly affects the speed, rotation accuracy, rigidity, vibration resistance, noise, temperature rise and thermal deformation of the machine tool, thus affecting the precision and surface quality of the machined parts.
