Detailed Description

The present invention will be further described with reference to the following examples.

The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. The condition in the embodiment can be further adjusted according to concrete condition the utility model discloses a it is right under the design prerequisite the utility model discloses a simple improvement of method all belongs to the utility model discloses the scope of claiming.

The utility model provides a sealed bearing please refer to fig. 1-4, including interior ring 1, the outside of interior ring 1 is provided with outer ring 3, has all seted up second spout 11 (see fig. 4) on outer ring 3 and the interior ring 1, can make outer ring 3 and interior ring 1 rotate through first ball 7 through second spout 11.
