16、hed and draft International Standards prepared by Technical Committee ISO/TC 4, Rolling bearings, of the International Organization for Standardization (ISO). In particular, the new ISO symbols for dimensions and tolerances have been adopted in this revision of BS 3134 and the series designations an
17、d boundary dimensions of the bearings comply with those given in ISO 355:1977 “Rolling bearings Metric tapered roller bearings Boundary dimensions and series designations”. Addenda to ISO 355 (in course of preparation) will cover the boundary dimensions of double row bearings and of flanged cups for
18、 roller bearings. These details will be added to BS 3134 in due course. In the light of metrication, it has been decided not to include inch series bearings in this edition. In support of industrys recommendation that the United Kingdom should change to the metric system, users should wherever possi
19、ble adopt metric bearings sizes for all new design applications. Where ball bearings, cylindrical and spherical roller bearings, instrument precision bearings, needle roller bearings, airframe bearings and accessories for use with rolling bearings are concerned, reference should respectively be made
20、 to the following British Standards: BS 292, Dimensions of ball bearings and cylindrical roller bearings1). BS 3469, Instrument precision rolling bearings (ball bearings). BS 5773, Metric needle roller bearings. BS 2SP, 89 Airframe bearings (roller bearings). BS 5646, Rolling bearings: accessories.
21、NOTETo facilitate the typesetting and printing of this standard, Table 1, Table 7, Table 8, Table 9, Table 10 and Table 11 and Figure 1 are identical with Tables 1, 2, 3, 4, 5 and 6 and Figure 1 in ISO 355:1977 which have been adopted in toto. In these tables, the comma has been used throughout as a
22、 decimal marker. In British Standards, it is current practice to use the full point on the baseline as the decimal marker. However, for the sake of uniformity in this standard the layout of Table 2, Table 3, Table 4, Table 5 and Table 6 is identical with the ISO layout. A British Standard does not p
23、urport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside fron
24、t cover, pages i and ii, pages 1 to 16, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. 1) To be revised to include spherical roller bearings.
