Foreword
This standard rule according to GB/T 1.1-2009 given draft.
This standard replaces GB/T 16940-1997 "linear motion bearings linear ball bearings - Boundary dimensions and tolerances", and
GB/T 16940-1997 compared to the main technical changes are as follows.
--- Modify the "standard name" (see cover and first page, and the 1997 version of the cover page);
--- An increase of some normative references (see Chapter 2);
--- Modify some of the terms and definitions (see Chapter 3, Section 3 of the 1997 edition);
--- Modify some symbols (see Chapter 4, Chapter 4 of the 1997 edition);
--- The dimensions table merge, delete the 2 series, 4 series, an increase of 5 series, also an increase of some 1 Series Overall feet
Inches (see Table 1, 1997 edition of the Tables 1 to 4);
--- Remove the 4 series of open type bearing structure diagram (see Fig. 3, 1997);
--- Remove the tolerance level of the L6M level, increasing the level and L6JA L6J level (see Chapter 6, Chapter 7, 1997 edition);
--- Increased tolerances are not applicable instructions bearing type (Table 3, Table 5, Table 7, Table A.1 footnote);
--- Added the stipulated tolerances (see 6.3);
--- Bearing tolerances of the basic scheme was changed to "informative appendix" (see Appendix A, 1997 edition Table 5);
--- Delete the provisions of the code method (1997 edition Appendix A).
This standard uses the translation method identical with ISO 10285.2007 "Rolling sleeve type linear ball bearings - Boundary dimensions and tolerances."
Correspondence between the consistency of the standards of international documents and normative references of the following documents.
--- GB/T 4199-2003 Rolling defined tolerances (ISO 1132-1.2000, MOD)

Introduction
Linear motion rolling linear motion different from the support provided by rotational movement of this type of bearing the standard of using balls as rolling elements,
In about the axis of the cylindrical body of the bearing raceway for several pieces of closed loop motion.
Linear ball bearings are usually used for one or more of the following requirements.
a) smooth low friction movement, no crawling or vibration;
b) the relative linear movement between the bearing and the shaft, only a small force.
The above requirements and other requirements, the proper use of various types of linear motion rolling bearings (closed sleeve type,
Adjustment sleeve type, sleeve type opening) to achieve. The user should consult the manufacturer and the type and size of the bearing a reasonable choice.
