A spherical roller bearing is a type of rolling element bearing that is designed to accommodate heavy radial loads and moderate to high axial loads in both directions. It consists of an inner ring with two raceways, an outer ring with a spherical raceway, and barrel-shaped rollers that are positioned between the raceways. The rollers are guided by a cage, which maintains their spacing and orientation.
In the event of a bearing failure, conducting a failure analysis can help identify the root cause and prevent future failures. Common causes of spherical roller bearing failures include inadequate lubrication, contamination, excessive loading, misalignment, improper handling during installation or removal, and fatigue. Understanding the failure mode can guide corrective actions and improve overall system reliability.
Preload is a predetermined internal axial load applied to a bearing to improve its rigidity and eliminate clearance in the rolling elements. However, spherical roller bearings are typically used without preload, as their design and self-aligning capability allow them to accommodate misalignment and operating conditions without the need for preload.
