  • Knowing the causes and solutions for bearing issues

    2017-10-24 · In the case of corrosion in the ball race, an abrasive material such as rust is left, which results in wear. This, then, leads to greater radial clearance or preload loss. If a bearing is grease-lubricated, the wear debris may hamper lubrication. Over time, successive overheating issues and lubrication failure arise.
