Ball and roller bearings are used in some aircraft jet engines. However, all industrial gas turbines use journal bearings. Journal bearings can be split or full-round. Large-size bearings used for heavy machinery normally have heavy lining. Precision insert-type bearings used commonly in internal coustion engines have a thin lining.

Ball Bearing Lubricants - S Bearings, EZO bearings, Bearing …

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.
