Those with heavy damage or fractures are generally only fit for recycling. The remanufacturing process therefore begins with an expert assessment of bearing condition, to determine both suitability for remanufacture and the type and extent of work required. An important aspect that is often overlooked is to assess bearing condition in the context of its application, taking into account the bearing load, lubrication conditions and time in operation; this enables the nature of the problem that has caused the damage to be fully understood.
