The Composition of the Fundamental Code of the Carousel Bearing

The fundamental code is divided into three parts, the front is the construction type and the drive type code, the middle is the rolling body diameter (for the bearing of the two rows or more rolling body is the maximum rolling body diameter), and the rear is the rolling weight centiyuan diameter (for the bearing of the two rows or more rolling body is the maximum rolling weight centiyuan diameter)

1.       the stereotyped code according to the rules of Table 1.

01 four-point contact ball bearings; 02 double-row off-diameter ball bearings; 11 interspersed cylindrical roller bearings; 13 three rows of cylindrical rollers with bearings.

2.       the transmission type code according to the rules of table 2.

0 toothless; 1 gradual open line cylindrical gear outer teeth smaller module; 2 gradual open line cylindrical gear outer teeth larger module; 3 gradual open line cylindrical gear inner teeth smaller module; 4 gradual open line cylindrical gear inner teeth larger module.

3.       the basic code preparation rules

When the basic code is arranged, the stereotype and the transmission type code are written in a series, and the "." is used between the front, center and rear. Separated.
