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 Noise | Lily Bearing

Ball Bearing Noise. Bearing acoustical noise is a function of both the bearing itself and the way in which it is used. Bearings can be specified as 100% noise-tested during manufacture. Bearing noise is not generally influenced by ABEC precision, but rather by manufacturers'' internal quality standards, particularly raceway finish.
