Wheel Luoyang bearing code representation

Bearing Code by simply code and post code form.Fundamental code is divided into three parts, Luoyang bearing the first part of the code structure types and drive types, central rolling diameter (for more than two rows of rolling element bearings for maximum rolling element diameter), Luoyang bearing heart weight rear rolling circle diameter (for two rows above the rolling bearing body weight for maximum heart rolling circle diameter) 1, structure type code according to the rules in Table 1. 01 four-point contact ball bearings; 02 double Reducing ball bearings; 11 interspersed cylindrical roller bearings; 13 with three-row cylindrical roller bearings. 2, Slewing Bearing transmission type code according to the rules in Table 2. 0 Toothless; an outer involute cylindrical gear teeth smaller modulus; 2 Luoyang bearing involute cylindrical gear outer teeth larger modulus; 3 involute cylindrical gear teeth within a smaller modulus; 4 involute cylindrical gears inner teeth larger modulus. 3, the fundamental rules of the code compiled Fundamental code layout, the structure type code and transmission type code writing for the front, middle and rear with between.
