High precision specifications are standard. A Robust series of angular contact ball bearings for sustaining axial loads that achieves high-speed and high rigidity performance. The BTR series has a contact angle of 40° that features both high thrust rigidity and low heat generation properties.Angular contact ball bearings Available in a wide selection of designs and materials – including four ISO dimension series in numerous executions – these bearings can be incorporated into virtually every application where precision bearings are required.

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.
