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.

Ball bearing - Wikipedia
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most

Bearing Grades and Quality - Fit Werx
In this rating system, the lower the nuer the better the quality of the bearing and the harder and better finished the bearing. For example, a Grade 25 is round to 25/1,000,000″, while a Grade 1000 is round only to 1000/1,000,000″. For perspective, loose bearings found in a Shimano Dura Ace hub, would often be Grade 25.
