slim ball bearing components are respectively

 1.according to the number of rolling body, divided into:

1) single row bearings -- with a rolling body bearing;

2) double row bearings -- with two rows of rolling bodies bearing;

3) multi row bearing - slim ball bearing‍ with more than two rows of rolling bodies bearing, such as the three column, four row bearings.

2.according to their components are respectively, divided into:

1) respectively, has respectively bearing bearing components;

2) can not be separately - bearing in the final after supporting bearings, rings are not bearing any free respectively.

3.according to their structural shapes high precision bearings‍ (such as with or without filling slots, with or without inner, outer ring and ring shape, structure, retaining edge very

To non retaining frame) can also be divided into structural types.                                                        ‍
