This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents"
drafted:
This document replaces GB/T 24604-2009 "Thrust Angular Contact Ball Bearings for Rolling Bearing Machine Tool Screws", and GB/T 24604-
Compared with:2009, except for editorial changes, the main technical changes are as follows:
a) Added ZKLN, ZKLF bidirectional thrust angular contact ball bearings and FU and FUB cylindrical single bearings with flanged housings
The structural type, code method and external dimensions of the element (see Figure 2 to Figure 4, Chapter 6, Table 7 to Table 9 and Appendix A);
b) Added the housing material, heat treatment quality and tolerance requirements for the FU type cylindrical unit with flanged housing (see 9:1:1 and
table 11);
c) Added the preload and starting friction torque requirements for ZKLN and ZKLF double-way thrust angular contact ball bearings (see Table 16);
d) The requirements for the amount of grease and grease filling are added (see 9:8);
e) Modified the inspection rules for bearing contact angle and starting friction torque (see Table 17, 9:3 of the:2009 edition):
