NSK - 5304C3 - Double Row Angular Contact Ball Bearings

NSK comprehensive range of angular contact ball bearings is designed to meet the ever-evolving requirements of equipment manufacturers.
Angular contact ball bearings feature a contact angle that sustains significant axial loads in one direction at the same time as radial loads.
Since an axial component is generated when radial load is applied, these bearings are typically used in pairs or multi-bearing sets., The structure of angular contact ball bearings produces an axial component when a radial or combined load is applied; therefore, two opposed bearings or a multi-bearing arrangement are used.
A preload is often used to increase the rigidity of single-row angular contact ball bearings, particularly in the main spindles of machine tools where high running accuracy is crucial.
