The fatigued surfaces result from repeated deformation between roller and raceways. The stress cycle of this action is a function of load and speed and causes high stresses at the roller and raceway contact. Generally, such damage runs to a depth of .002 inch or less. The material at the contact area is fatigued by the bending action and will be the nucleus for coarse grain spalling, if operation continues until the material stress limit is reached.
By grinding away the fatigued material, new contact surfaces are provided and in conjunction with the proper geometry, a new bearing is manufactured. The process of remanufacturing is as complex as new manufacturing, for tolerance, finishes and geometry. Calculations, dimensions, angles and finishes must meet the accuracies of a new bearing.
The savings to our customers result from using the existing races as raw material for the remanufactured bearing. The savings can be substantial, while providing a bearing equal to or better than the original. The savings is not only in money but, in time, as the raw material is already delivered.
