Overview
This high-precision angular contact ball bearing set is engineered specifically for demanding industrial applications requiring exceptional rotational accuracy and speed. Designed with a compact footprint, the unit features a 0.98-inch bore diameter and a 1.85-inch outside diameter, with a total width of 0.47 inches. The construction utilizes advanced phenolic resin cages, which provide superior thermal stability and significant weight reduction compared to traditional metal cage alternatives. These bearings are supplied as a matched pair within a four-unit package, ensuring optimized preload settings that deliver enhanced rigidity and minimal axial runout. This configuration makes them an ideal solution for machine tool spindles and precision instrumentation where strict tolerance control and consistent operational efficiency are critical.
Key Features
Matched pair configuration for optimized preload and increased system rigidity Phenolic resin cage construction offers excellent thermal resistance and reduced rotational mass Precision ground races ensure minimal axial runout and smooth high-speed operation Compact design with a 0.98-inch bore fits standard high-precision spindle requirements Superior dimensional stability under varying temperature conditions Engineered for extended service life in continuous duty cycles
