What are the benefits of preload for bearings?

The so-called bearing clearance refers to the amount of movement when the bearing is not mounted on the shaft or the bearing box, when the inner ring or the outer ring is fixed on one side, and then the unfixed side is moved in radial or axial direction.

Tiejian Heavy Industry self-developed main bearing of roadheading machine, entering the stage of batch engineering applications

Main As the core key components, the bearings work in underground tunnels for a long time, and their reliability and safety requirements are extremely high. Once a failure occurs, it is difficult to dismantle and replace them, which will lead to construction paralysis and cause huge losses. In the past, due to the lack of test and application data support, it is difficult to effectively verify the reliability of the product, and it is difficult to promote the engineering application.

Lingbi bearing: “into” the development of the Guzhong highland

In recent years, Lingbi County to seize the Yangtze River Delta regional integration and development, northern Anhui to undertake industrial transfer agglomeration area construction, the county's new urbanisation to make up for the shortcomings and strengthen the weakness of the demonstration of the construction of major national strategies, anchored in bearing characteristics of the industry as the leader of the main direction of the development of intelligent equipment manufacturing industrial clusters, and strive to build a high-quality bearings in the country has an important influence on the production base.
