JB/T 6362-1995 Rolling bearings Bidirectional thrust angular contact ball bearings for machine tool spindles

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.

JB/T6362 | | tt | Shou. This standard replaces the content of JB/T6362-92 "Rolling Bearing Bidirectional Thrust Angular Contact Ball Bearing Outline Dimensions", expands the size range of the 2344 and 2347 series, adds the size tables of the 2349 and 2349X series, and replaces the J13538691 machine The technical requirements for finished products of bidirectional thrust angular contact ball auxiliary bearings in "Supplementary Technical Conditions for Ball Main and Auxiliary 1 Precision Rolling Bearings" are opened and expanded to a wide range of sizes. The provisions for grouping of preloaded bearings are added.
This standard will replace JB/T6362·92 and partially replace JB5386--91 from the date of implementation.
Appendix A of this standard is a reminder appendix.
This standard is proposed by the National Rolling Bearing Standardization Technical Committee. This standard is administered by the Luoyang Bearing Research Institute of the Ministry of Machinery Industry. This standard was drafted by: Harbin Bearing Co., Ltd. This standard was drafted by: Yong Taifang, Pang Jun. This standard was first formulated in 1992.
