FAG | B71904C-2RSD-TP4SUL | Bearing

Single-row super precision sealed angular contact spindle bearing that cannot be dismantled. The bearing has solid inner and outer rings and ball-and-cage assemblies with solid window cages. Due to their extremely tight tolerances, they are particularly suitable for applications that require high guidance accuracy and suitability for high speeds. Spindle bearings are commonly used for main spindles in machine tools. Additionally, this bearing is designed as a universal bearing. Universal bearings with the same deviation in the inner ring bore and outer diameter can be combined in different arrangements. For example, when the load capacity of a single bearing is insufficient, two matching bearings can be used in a tandem arrangement to support axial loads in one direction only.
