Foreword
This Standard was drafted in accordance with the rules given in GB/T
1.1-2009.
This Standard replaces GB/T 4663-1994 Rolling bearings - Cylindrical thrust
roller bearings - Boundary dimensions. Compared with GB/T 4663-1994, in
addition to the editorial modifications, the main technical changes are as
follows.
- added “Terms and definitions” and “Codes” (see Clause 3, Clause 5 of
this Edition);
- added models and dimensions for 11 series of bearings of some
one-way cylindrical thrust roller bearings (see Table 1 of this Edition,
Table 1 of Edition 1994);
- added the structural type and boundary dimensions of two-way
cylindrical thrust roller bearings (see Table 2, Table 3 of this Edition);
- deleted “old and new bearing code contrast” (see Annex A of Edition
1994).
This Standard was proposed by China Machinery Industry Federation.
This Standard shall be under the jurisdiction of National Technical Committee
on Rolling Bearings of Standardization Administration of China (SAC/TC 98).
