Bearing designations | SKF |
The basic designations of SKF tapered roller bearings start with the letter T, e.g. T2ED 045. Designations established prior to 1977 are based on the system shown under Basic designations, e.g. 32206 . Metric bearings with the designation prefix J follow the ABMA designation system, which is used for inch bearings (ANSI/ABMA Std. 19.1).
