ABMA 19.2:2013 pdf free.Tapered Roller Bearings,Radial Inch Design
The bearings listed in the Boundary Dimension Tables (3-6) are those in common use. The tables are designed to minimize the number of inch design tapered roller bearings, yet satisfy present and future needs of bearing users. These tables do not contain any indication as to availability of bearings.ABMA maintains a clearinghouse of dimensions affecting tapered roller bearing interchangeability for additional part numbers not listed in this standard.
Bearing mounting designs must afford adequate clearance for the cage. It should be noted that often the small end of the cage extends beyond the faces of the cup and cone.Consult the bearing manufacturer for additional information and application. See Figure 1.
The effective load center of the bearing is a theoretical point about which moments are taken to determine bearing loads or reactions. In using the effective load center, only externally applied loads need to be considered. The location of the effective load center is shown in the manufacturer’s catalogue. Consult the bearing manufacturer for additional information and application.See Figure 1.
Table 1 shows the types of tapered roller bearing assemblies which appear in the Boundary Dimension Tables, with a brief description and a typical ilustration of each type.Other types of single row, two row, and four row tapered roller bearing assemblies, with or without spacers,are available. Individual bearing manufacturers should be consulted for further details.
Bearing assembly types TDI, TDO and TDOCD listed in Table 1 are not shown with spacers.These bearing assembly types can be furnished by the manufacturer with spacers. Spacers are made of both hardened and unhardened steel of numerous configurations. Table 2 lists common types of spacer design along with their type designations. Consult individual manufacturers for availability. When these bearing assembly types are fitted with spacers, they are furnished as pre-set assemblies in which the spacers have been finished to size to establish a pre-determined axial clearance within each bearing assembly. Therefore component parts from one assembly are not interchangeable with similar assemblies even if made by the same manufacturer. Because spacer assemblies are pre-set by the manufacturer,spacers are generally not sold separately.ABMA 19.2 pdf free download.
