A recycler was experiencing regular failures of a mounted bearing unit on an optical sorting conveyor. In the three months after installation of the machine, a total of 5 bearing failures were recorded. An NSK application engineer examined the application and determined that vibration and lubrication issues were causing the bearing to fail prematurely. NSK recommended using SNN Plummer Blocks combined with NSKHPS Spherical Roller Bearings.
