ISO 7148 Tribological Performance Testing of AM Bearing Materials
The ISO 7148 standard is a critical tool for manufacturers and quality assurance teams in the aerospace and automotive industries. This testing ensures that additive manufactured (AM) bearing materials meet or exceed stringent tribological performance criteria, which are crucial for the reliability and longevity of components used in these sectors.
Quality managers, compliance officers, and R&D engineers rely on this test to verify that the properties of AM bearings align with the mechanical demands they will face in use. The testing process involves subjecting specimens under controlled conditions to simulate real-world operating environments, ensuring that any potential weaknesses are identified before components enter service.
The ISO 7148 standard is particularly important for aerospace and automotive applications due to the high-stress environments these industries operate in. Tribological performance encompasses a range of factors including wear resistance, friction behavior, and load-carrying capacity. Ensuring that AM materials meet these criteria not only enhances product reliability but also helps reduce maintenance costs and extend operational lifetimes.
Testing involves the use of specialized tribometers capable of replicating the dynamic conditions under which bearings operate. Specimens are subjected to varying loads, speeds, and lubrication types to assess their performance across a range of operating parameters. This ensures that the materials used in AM processes can withstand the rigors of real-world applications.
The process begins with careful specimen preparation, ensuring that each sample is representative of the final product. Once prepared, the specimens are subjected to a series of tests designed to evaluate their tribological properties under controlled conditions. The results provide critical insights into how well the materials perform in terms of wear resistance and frictional behavior.
Compliance officers will find this testing particularly valuable as it provides clear, quantitative data that can be used to demonstrate adherence to industry standards. R&D engineers benefit from a deeper understanding of material performance under specific conditions, which can inform process improvements and innovation. For procurement teams, the results offer reassurance that the materials they source meet the highest quality standards.
The testing procedure typically involves several stages: specimen preparation, initial inspection, tribological testing, data analysis, and reporting. Each step is meticulously documented to ensure reproducibility and traceability of results. The final report includes detailed descriptions of test conditions, performance metrics, and any deviations from expected behavior.
By adhering to the ISO 7148 standard, manufacturers can demonstrate their commitment to quality and reliability, ensuring that AM components perform as expected in critical applications. This not only enhances customer confidence but also supports ongoing efforts to improve product design and manufacturing processes.

The scope of ISO 7148 tribological performance testing encompasses a wide range of parameters that simulate the operational conditions faced by bearings in real-world applications. Specimens are prepared with specific surface finishes and dimensions to ensure accurate representation of final products.
The testing process begins with initial inspection of each specimen, ensuring they meet predefined quality criteria before proceeding to tribological tests. The tribometer applies controlled loading, speed, and lubricant conditions to assess wear rates, friction coefficients, and load-carrying capacities under various operating scenarios.
Data collected during these tests is analyzed using advanced software tools that provide detailed insights into the performance of each material. These analyses are then compiled into comprehensive reports, which serve as a reference for quality assurance teams and R&D engineers.
