What Are the Causes of Machine Tool Bearing Raceway Spalling?
Raceway spalling in machine tool bearings is a serious form of surface fatigue that results from repeated stress, poor lubrication, misalignment, or contamination. This leads to material flaking on the raceway surface, causing vibration, loss of precision, and eventual bearing failure. Understanding the root causes and implementing proper maintenance, lubrication, and load control are essential to extending bearing life and maintaining machining accuracy.
