    A newly developed diagnosis system detects several critical states at the same time (1). Te procedure serves for the determination of over-lubrication and under-lubrication, ageing of lubricant, pollution of lubricant by coolant or water, damage to the race surfaces due to abrasive wear or fatigue as well as overload. The experiments discussed in this article show, among other things, that the measuring of the temperature at the outer bearing ring is a suitable method for determine changes in the lubrication.
