13、12-1999 National foreword This British Standard has been prepared under the direction of the Mechanical Engineering Standards Committee and forms part of a series implementing corresponding International Standards in the development of which the United Kingdom has played an active part. This Part of
14、 this British Standard is identical with ISO 6278:1980 “Needle roller bearings Track rollers Boundary dimensions” prepared by Technical Committee ISO/TC 4, Rolling bearings, of the International Organization for Standardization (ISO). Terminology and conventions. The text of the International Standa
15、rd has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following.
