Super Precision High Speed Angular Contact Ball Bearings are designed for rigid, high speed, high tolerance applications. Spindle bearings used in pairs in a ‘back to back’ or ‘face to face’ arrangemet can support axial forces on both directions and moments. Bearings in a tandem arrangement can only support axial loads in one direction.

 

In angular contact ball bearings for high speeds, small internal axial forces appear after changes in rotational speed which are caused by centrifugal forces acting on the elements of bearings and on the spindle, as well as by the gyroscopic moment.Bearing has developed new ultra-high speed Angular Contact Ball Bearings using the new cage “SURSAVE" for the main spindle of machine tools. This cage is applied to the series of ultra-high speed angular contact bearings. Low NRRO, low heat generation and high-speed performance are achieved with the newly developed cage“SURSAVE”.
