This document specifies а method for the determination of the endurance limit in fatigue of bearing materials alone (not attached to steel backing).
Abstract
Overview
ISO 7905-2:2021 specifies a laboratory method to determine the endurance limit in fatigue of metallic plain bearing materials tested as standalone specimens (i.e., not bonded to steel backing). The method uses a polished, cylindrical specimen and an axial oscillating load to reproduce the cyclic stresses that cause bearing fatigue. Results are presented as stress–number (S–N or Wöhler) curves and evaluated statistically to define endurance limits under controlled test conditions.
Key topics and requirements
- Specimen geometry and surface finish: Cylindrical specimens manufactured in accordance with the standard’s figure and polished to be representative of production bearing surfaces. Surface roughness is specified as **R
