WebJan 20, 2014 · tbuelna (Aerospace) 21 Jan 14 22:22. crunchie12268-. Oil lubed rolling element bearings, like your cylindrical roller bearing, incur two basic types of mechanical loss- frictional loss and viscous loss. With a high DN bearing, the viscous losses will predominate. With a lower DN bearing, the friction and viscous losses may be fairly similar. N = bearing speed. This is the maximum amount of revolutions per minute (RPM) that the bearing will move. The DN factor of a bearing is obtained by multiplying the median diameter (A + B)/2 by RPM, and sometimes by a correction factor. This correction factor may vary from manufacturer to manufacturer. See more DN Factor, also called DN Value, is a number that is used to determine the correct base oil viscosity for the lubrication of various types of bearings. It can also be used to determine if a bearing is the … See more For a single or double row cylindrical bearing, the following formula would be used to obtain the DN factor. It includes a correction factor of 2: See more Once the DN factor of a bearing has been obtained, it can be used to consult grease selection charts in order to determine the correct lubricant. Viscosity must be matched to the needs of the bearing in order to obtain maximum efficiency, and to avoid lubricant … See more WebPrefix DN or NPS usage is applicable to steel valves bearing PN or Class (3.1) designations.
