Application of tribology for enhancing the life of sugar mill roll bearing and journal* [Full subscriber]

Sugar mill roll top journal bearing functions predominantly under boundary lubrication regime due to heavy load and small sliding velocity. This bearing is prone to ingress of juice/bagasse and other contaminants due to their floating condition. In many cases, the design of the mill roll top journal bearings and their lubricating grooves happen to be insufficient to reduce the temperature rise and consequently thermal expansion of the mating components. This leads to premature failures of roll top journal bearings. Thus, an attempt has been made herein to design and develop an improved sugar mill roll top journal bearing by application…
