14、dardization) is a worldwide federation of national standards bodies (ISO member 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
15、 to be represented on that committee. International organizations, governmental 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 S
16、tandards are drafted in accordance with the rules given in the ISO/IEC Directives, 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
17、International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13
18、012-2 was prepared by Technical Committee ISO/TC 4, Rolling bearings, Subcommittee SC 11, Linear motion rolling bearings.

20、ort rails. These items, referred to as accessories, can aid in the application of the sleeve type linear ball bearings to achieve the desired criteria of smooth, accurate, low-friction linear motion free from chatter or stick-slip. The appropriate selection of bearing housing type, shaft and shaft s
21、upport should be established between the manufacturer and the user. This part of ISO 13012 was developed to be used with ISO 10285.

Included in this part of ISO 13012 are the boundary dimensions and other related dimensions
44、of sleeve type linear ball bearings series 5 as specified in ISO 10285:2007. The housings specified in Tables 1 and 2, and the corresponding sleeve type linear ball bearings should be supplied by the same producer. The reason for this is that the fixation of the bearings in the housings is specified
45、 by the producer and is not covered by this part of ISO 13012. 5.2 Housings for series 5 sleeve type linear ball bearings This part of ISO 13012 includes the following housing designs for series 5 linear ball bearings: closed and adjustable flangeless housings for series 5 sleeve type linear ball be
46、arings (Table 1); open and open adjustable flangeless housings for series 5 sleeve type linear ball bearings (Table 2). 6 Shaft support rails This part of ISO 13012 includes the following shaft support rails for sleeve type linear ball bearings: standard height shaft support rails for series 5 sleev
47、e type linear ball bearings (Table 3). 7 Shaft support blocks This part of ISO 13012 includes the following shaft support blocks for sleeve type linear ball bearings: flanged shaft support blocks for series 5 sleeve type linear ball bearings (Table 4). 8 Shafts 8.1 Material Shafts covered by this pa
48、rt of ISO 13012 are precision hardened and ground steel shafts in both solid and tubular section. They are manufactured from high quality carbon steel or high quality carbon chrome steel and are either surface hardened or through hardened. 8.2 Heat treatment 8.2.1 Surface hardened shafts The cylindr
49、ical surface of the shafts is heat treated to provide a basically uniform effective depth of hardening and a surface hardness of not less than 653 HV (58 HRC) over the entire operating length. The effective depth of hardening shall be determined in accordance with ISO 3754. This effective depth of hardening is the distance from the outside surface of the shaft to a material layer at which the hardness is approximately 80 % of the specified minimum surface
