Description
Pair Precision Angular Contact Bearings: Spindle bearings are super-precision single row angular contact ball bearings with solid outer and inner rings, ball and cage assemblies and solid window cages.
Benefits: Due to their very narrow tolerances, the spindle bearings are particularly suitable for applications involving the highest requirements for guidance accuracy, such as bearing arrangements for main spindles in machine tools.
