The external dimensions of the bidirectional thrust angular contact ball bearings specified in this standard adopt the external dimensions of similar bearings in the world. This standard will replace all the contents of JB/T 6362-92, expand the size range of the 2344 and 2347 series, add the size tables of the 2349 and 2349X series, and incorporate JB 5386-91 into the technical requirements for finished products of bidirectional thrust angular contact bearings Incorporated, the size range is expanded, and the bearing preload grouping section is added. This standard specifies the overall dimensions and finished product technical requirements of 2344, 2347, 2349, and 2349X series bidirectional thrust contact ball bearings for machine tool spindles. This standard applies to the manufacturing, inspection and acceptance of bearings.
