Standard spindle bearings are single-row angular contact ball bearings with high precision and rigidity, specially designed for use in machine tools, spindle systems and high-speed drives. Thanks to optimised raceway geometries and defined contact angles (usually 15° or 25°), they can reliably absorb combined radial and axial forces.
The bearings are available in various preload classes and accuracy grades and offer excellent concentricity properties combined with smooth running behaviour. Depending on the design, they are open or sealed, grease-lubricated or designed for oil lubrication.
Thanks to their precise manufacturing, high speed limits and stable thermal properties, standard spindle bearings ensure consistently high machining quality and process reliability – even under demanding operating conditions.
