High-speed bearings can be classified in various ways, such as by rolling element type, load direction, or structural configuration. Common classifications for high-speed applications include high-speed ball bearings (e.g., angular contact ball bearings, deep groove ball bearings) and high-speed roller bearings (e.g., cylindrical roller bearings, tapered roller bearings, spherical roller bearings). Classification based on specialized technology and materials includes hybrid ceramic ball bearings, which utilize ceramic rolling elements.
Examples of high-speed ball bearing models include angular contact ball bearings such as FAG B7236E.T.P4S.UL, NTN 7215BDT, and NTN 7210CDB, as well as deep groove ball bearings such as FAG 6314-Z, NTN 6918LLB, and NTN 6319N. Examples of high-speed roller bearing models include spherical roller bearings such as NSK 23030CCK/W33, NTN 22348BKD1+H2348, FAG 2220, and NACHI 24128EW33; cylindrical roller bearings such as NTN NJ210, SKF N2328, and NSK HJ2211E; tapered roller bearings such as TIMKEN 95512/95927CD, NSK 30336, TIMKEN 2582/2523, and NSK 48620; and the KOYO 29417 thrust roller bearing. Examples of other bearing types include the IKO TAF1-9512536 needle roller bearing and the NSK 51206 thrust ball bearing.
