The wear resistance of oil bearings refers to the ability to withstand wear, measured by wear volume or service life. To achieve wear resistance, it primarily depends on the properties of the raw materials, as well as the organizational structure and lubrication conditions. For instance, materials with a spheroidal structure are highly wear-resistant.

To ensure sufficient self-lubricating properties, iron-based oil-impregnated bearings must possess certain porosity and open pore degree on the working surface, with the pores being as interconnected as possible. Only then will the self-lubricating performance of such bearings be stable.
