Deformations: Bearing deformations can occur in several different ways. Excess heat can cause metal flow, which can result in rib face deformations in the bearing cones. Deformation can cause rollers to skew and the bearing to lock up entirely.
Fatigue spalling: This is a type of damage to the metal surface. Inclusion spalling results from oxides or other hard inclusions in the steel of the bearing. Point surface spalling occurs because a raised surface or debris exceeds the thickness of the bearing lubrication film. In both types of spalling, the metal will begin breaking away from the raceway.
Handling damage: Damage caused by rough transport or installation often exhibits as denting or nicking—raised metal due to contact with roller/ball edges.
Cage damage: Bearings that were dropped or incorrectly installed often result in cage damage. When this occurs, rollers/ balls tend to skew and bind, and the cage ring gets obstructed during operation or installation.
Preload/overload damage: Excessive bearing preload or overload can damage roller bearings in different ways. Preload settings that are too tight could also lead to cone bore contraction. Full race width fatigue spalling can occur due to heavy loads that create a layer of lubricant and high temperatures.
When Should You Replace Your Bearing?
It can be difficult to know when to replace your roller bearing since the amount of time between the initial damage and when the bearing becomes unserviceable can differ significantly. High-speed bearings can be destroyed in seconds. Low-speed bearings can take months to break down. Early diagnosis of a damaged bearing is essential so that the bearing can be replaced before it fails completely, at which point it can also damage the machine and other components.
Noting early indications of damage allows bearings to be replaced during regular bearing maintenance, preventing costly, unexpected downtime due to bearing failure. Inspectors should monitor machines for unusual noise, vibration, and temperature. Identifying and addressing the causes of these symptoms will prevent further damage to the system.
