Identification Code. Inch design tapered roller bearings are numbered in an identical manner or reference is made to the universal number by all producers. Therefore, an identification code for the use of bearing users to provide a universal language for describing and identifying these products is not required.
Individual Component Part Numbers.Unlike other bearing types, tapered roller bearing cones and cups are individually numbered. The cone is assembled with rollers and a cage, and when used with a cup, makes a complete bearing assembly. Both cone and cupnumbers are required to identify a complete bearing assembly. The cone number followed by the cup number is the preferred practice.
The bearing series indication will be related to the maximum theoretical bore of the bearing or the diameter of the cone at the small end of the roller, in order that smaller numbers will indicate smaller sizes of bearings and larger numbers will indicate larger sizes of bearings.
For the present, the series numbers indicated by the absence of any digit or by the single digit 0 to 9 inclusive, have been reserved for future development of extremely small sized tapered roller bearings, if required.
Likewise, the numbers 900 to 999, inclusive,have been reserved for future development of extremely large bore tapered roller bearings, if required.
The selection of the basic series indication in relation to the maximum theoretical bore of the bearing will then be in accordance with the tabulation below.
Cup numbers will be indicated by the digits 10 to 19, inclusive, the first cup made to minimum section in any series starting with the number 10. If more numbers are required in any series,numbers 20 and up will be utilized where available.
Cone numbers will be indicated by the digits 30 to 49, inclusive, the first cone made to minimum section in any series being numbered 49.If more numbers are required for the cones in any one series, number 29 and below will be utilized where available.ANSI ABMA 19.2 pdf free download.
