11、bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental

12、and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directive

13、s, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies c

16、rights reservedIntroduction Four-point-contact ball bearings are radial single-row angular contact ball bearings with raceways that are designed to support axial loads in both directions. The axial clearance values apply to bearings supporting pure axial load in both directions, which are not mounte

17、d or preloaded and are not being subjected to any external load (i.e. with no measuring load being applied). Depending on the design of the bearing and verification method, some dispersion of the results of measurements can be experienced due to verification uncertainties. Manufacturers and users ar

NOTE For the convenience of users of this part of ISO 5753, the following definitions are reproduced. 3.1 axial internal clearance Gabearing capable of taking axial load in both directions, non-preloaded arithmetical mean of the axial distances

22、 through which one of the rings may be displaced relative to the other, from one axial extreme position to the opposite extreme position, without being subjected to any external load NOTE 1 The mean value includes displacements with the rings in different angular positions relative to each other and

23、 with the set of rolling elements in different angular positions in relation to the rings. NOTE 2 For a measurement to be valid, at each limiting axial position of the rings in relation to each other, their relative radial position, and the position of the rolling elements relative to the raceways,

24、shall be such that the one ring has actually assumed the extreme axial position in relation to the other ring.
