S Bearings, EZO bearings, Bearing Relubriion Services - Detailed Information on Types of Bearing Lubriion

Greases have speed ratings sometimes called “DN” ratings. The calculation for the “DN” of an appliion is as follows: Speed in rpm x (bearing ID + bearing OD) ÷ 2. Assume a bearing rotates at 20,000 rpm. The bearing ID is 8mm and the OD is 22mm. The above formula produces a DN of 300,000 so the grease should be rated above this figure.

Noise measurement in ball and roller bearings - ICT

It tends to occur with relatively large bearings used under a radial load, especially in cylindrical roller bearings, but sometimes also in ball bearings. It seems due to the friction between the outer ring and the rolling elements, but it is not clear if this contact is happening in the load zone or in the no-load zone.
