Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a bearing with liner structure, includes bearing shell 1, bearing inner shell 2 and

ball

4, and 1 inboard of bearing shell rotates through ball 4 and sealing washer 5 and is connected with bearing inner shell 2, and terminal surface fixedly connected with dull polish circle 7 before the bearing inner shell 2, and the spacing hole 15 of second has been seted up to the terminal surface inboard before the bearing shell 1, has seted up maintenance hole 3 in the middle of the 1 outside of bearing shell.
