Description

Split type bearing

Technical Field

The utility model relates to the technical field of bearings, in particular to a split bearing.

Background

Bearings are an important component in contemporary mechanical devices. Its main function is to support the mechanical rotator, reduce the friction coefficient in the course of its movement and ensure that its rotation precision bearing can be divided into rolling bearing and sliding bearing. The rolling bearing is a common standard component, has the advantages of low friction coefficient, small starting resistance and the like, and is convenient to design, use, lubricate and maintain.
