A customer was experiencing repeated bearing failures on their blade saw pulleys within the cake cutting units. Bearings were failing every 4-6 weeks with approximately 20 bearing sets beign changed annually. Investigation by NSK showed the failures were caused by the ingress of water and hard particulates. NSK recommended replacing the standard bearings with NSK Molded-Oil units. With tested bearings life lasted up to 26 weeks, this improved productivity and offered cost saving in replacement and maintenance time.
