For this reason, the possibility of reaching conclusions about the cause of a defect by means of studying its appearance is very useful. SKF coatings . 1. Through the prudent use of temperature and vibration monitoring equipment, routine oil analysis, lubrication system evaluations and machine operational performance reviews, bearing distress may be identified and evaluated before catastrophic failure occurs. Such damage, known as pri-mary damage, gives rise to secondary, The knowledge collected on bearing damage is accessible for SKF engineers as a Web-enabled decision-support system called SKF Bearing Inspector. A systematic procedure should be implemented to assist in resolving bearing failures. When a bearing does fail prematurely, it is usually due to causes that could have been avoided. Bearing internal clearance is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance).
