15、on of surface texture in technical product documentation DIN ISO 13012-2:2010-02 Introduction The use of sleeve type linear ball bearings can be facilitated by the selection of bearing housings, shafts, shaft support blocks and shaft support rails. These items, referred to as accessories, can aid in

16、 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 support should be established between the manufacturer and the

17、user.

Included in this part of ISO 13012 are the boundary dimensions and other related dimensions of sleeve type line

39、ar 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 by the producer an

41、pen 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 sleeve type linear ball

42、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 bl ocks for series 5 sleeve type linear ball bearings (Table 4). 8 Shafts 8.1 Material Shafts covered by this part of ISO 13012 ar

43、e 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 cylindrical surface of th

44、e 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 di

45、stance from the outside surface of the shaft to a material layer at which the hardness is approximately 80 % of the specified minimum surface hardness. End faces of shafts may remain unhardened. 10 DIN ISO 13012-2:2010-02 8.2.2 Through hardened shafts The shafts shall be heat treated to give a surfa

46、ce hardness of no less than 653 HV (58 HRC) over the entire operating length. 8.3 Geometrical tolerances 8.3.1 Tolerance class The precision hardened and ground solid and tubular shafts are specified in one diameter tolerance class to match the sleeve type linear ball bearing and housing series 5. 8

47、.3.2 Geometric form The geometric form of the tolerance class is controlled by the following features: a) circularity (roundness): variation of shaft outside diameter in a single plane; b) cylindricity (taper, concavity, convexity): variation of mean shaft outside diameter; c) straightness (per metr

48、e). These tolerances for the class are shown in Table 5. A method for measuring straightness is illustrated in Figure 5 and defined in Table 5. 8.3.3 Shaft length tolerances These tolerances are given in Table 6. 8.3.4 Chamfers The shaft ends are provided with chamfers to facilitate entry of the sha

49、ft into the sleeve type linear ball bearing. The ends of shafts with machined end faces are usually provided with chamfers that are shallow in the radial direction and long in the axial direction. The length of the chamfer is shown in Table 5. Shafts for use with sealed sleeve type linear ball bearings shall have a chamfer angle less than 30. 8.3.5 Surface roughness The roughness of the cylindrical surface of the steel shaft is given in Table 5 in accordance with ISO 1302. 9 Bou
