Bearing Arrangement - an overview | ScienceDirect Topics

WTW (Bill) Cory, in Fans and Ventilation, 2005 10.10.1 Introduction. Whatever the bearing arrangement or type of bearing used, the bearings must be sealed to prevent contaminants and moisture entering the bearing in addition to retaining the lubricant. When seals are an integral part of a rolling element bearing, the bearing can be greased and sealed for life.
