S Bearings, EZO bearings, Bearing Relubriion Services - Ball …

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.

Common gearbox problems and diagnosis | The Gearbox Centre

Low-pitched growling or ruling noises when the engine is running are usually the sign of a faulty rolling-element (also known as a ball or roller) bearing. They are extremely sensitive to small bits of metal or dirt in the lubricant film between the bearing elements and cause the rollers to drag across the surface of the race.
