Cylindrical roller bearings; Separate thrust collars; Boundary dimensions

This document specifies the external dimensions and tolerances for separable thrust collar components used within roller bearing assemblies. It establishes a uniform framework for ensuring interchangeability and compatibility across various mechanical systems worldwide. The standard outlines precise measurements for critical features, including outer diameter, width, and chamfer dimensions, facilitating consistent manufacturing and assembly processes. By defining these geometric parameters, it supports the integration of thrust bearings in applications requiring axial load support, such as automotive transmissions, industrial machinery, and aerospace components. Adherence to these dimensional guidelines enables engineers to select appropriate parts with confidence, reducing the risk of misalignment or premature wear. The information presented focuses solely on the technical specifications required to produce and verify these separable thrust collar elements, serving as a reference for quality control and design validation in the production and maintenance of rotating machinery components.
