This document defines, describes and classifies the characteristics of damage occurring in service to hydrodynamically lubricated metallic plain bearings and journals. It assists in the understanding of the various characteristic forms of damage which can occur. Consideration is restricted to damage characteristics which have a well-defined appearance and which can be attributed to particular damage causes with a high degree of certainty. Various appearances are illustrated with photographs and diagrams.

Overview - ISO 7146-1:2019 (Plain bearings - Part 1: General)

ISO 7146-1:2019 defines, describes and classifies the visual and physical damage characteristics that occur in service on metallic, hydrodynamically lubricated plain bearings and journals. The standard focuses on damage forms with a well-defined appearance that can be attributed to likely causes with a high degree of certainty. It illustrates various appearances using photographs and diagrams and provides practical guidance for consistent damage characterization and analysis.

Keywords: ISO 7146-1:2019, plain bearings, hydrodynamic bearings, metallic plain bearings, bearing damage, damage characterization, bearing inspection, tribology, failure analysis.

Key topics and technical content

Definitions and terminology related to bearing damage and indicators of damage.

Systematic description of damage causes and their characteristic appearances, including:

Static overload and dynamic overload
Wear by friction
Overheating
Insufficient lubrication (starvation)
Contamination (particles and chemicals)
Cavitation erosion
Electroerosion
Hydrogen diffusion
Bond failure

Relationship between observed appearance and probable cause (damage characterization).

Detailed sections on:

Damage to the bearing surface (typical appearances, possible causes, examples)
Damage to the bearing back (including dynamic overload and wear)
Special positions of damage appearances

Practical guidelines for damage analysis, organized into a stepwise procedure (Step 1 through Step 5) to support systematic investigations.

Illustrative content: photographs, diagrams and an informative annex with example use of tabular guidance.

Practical applications - who uses this standard

Maintenance and reliability engineers conducting root-cause analysis of bearing failures.

Tribologists and failure analysts diagnosing wear, erosion, contamination and electrochemical damage.

OEMs and design engineers specifying bearing materials and lubrication systems for rotating machinery.

Inspection teams, asset managers and laboratory technicians preparing visual and photographic reports for warranty or forensic investigations.

Training and quality assurance programs aiming for consistent classification and reporting of bearing damage.

Related standards and notes

ISO 7146-1:2019 is Part 1 (General) of the ISO 7146 series; consult other parts of the series and related ISO standards on bearings and lubrication for complementary test methods, dimensional standards and material specifications.

The document is primarily a descriptive and diagnostic aid - it does not replace test procedures but supports consistent visual classification and interpretation of bearing damage.

For reliable bearing maintenance, use ISO 7146-1:2019 together with machine-specific maintenance practices, lubricant specifications and material data to achieve accurate failure diagnosis and effective corrective actions.
