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.
