Martin Bearing MaintenanceBearing Prefixes
Prefixes are used to identify components of a bearing and are usually then followed by the designation of the complete bearing, or to avoid confusion with other bearing designations. For example they are used in front of designations for tapered roller bearings according to a system described in ANSI/ABMA Standard 19 for (predominantly) inch bearings.
