WebdN values can be assigned to bearing types and their components such as retainers and lubricants. For example precision angular contact bearings should be limited to around 850,000 dN. Deep groove radial ball bearings with standard metal retainers should not exceed around 250,000 dN. WebBearing series designations consist of an identification for the bearing type and the dimension series. The most common series designations are shown in table 1 . The … WebThe higher the DN number, the greater the frictional heat that will be generated by the bearing. DN values above 350,000 produce a significant amount of heat, and require oil circulation through a cooler to maintain the proper oil viscosity in the bearing. Small oil consoles will solve the problem and result in a pump with a high MTBF. metier bachelor commerce
