Rolling basic application range

The operation of the sliding friction between the shaft and the shaft seat becomes rolling friction, thereby reducing the friction loss of a precision mechanical components, called Rolling. What is the working principle of a rolling bearing is it? Mainly used in what areas? What kind of performance? Here I come to tell you the relevant knowledge, I hope for your help.
 
Rolling is the use of rolling friction principle work support member having a small friction, easy to start, acceleration fast, compact, "three" (standardization, serialization, universal) high level, modern adaptation of various mechanical requirements performance and service life and easy maintenance features.
 
Rolling widely used in industrial (machine tools, mining, metallurgy, petrochemical, textile, electrical, medical, engineering machinery and various types of equipment, the instruments), agriculture (tractors and other agricultural machinery), transport (railway locomotives, cars, motorcycles vehicles, ships, aircraft, etc.), defense (ships, tanks, missiles, etc.), aerospace (satellites, rockets, spacecraft, etc.), household appliances (electric fans, washing machines, vacuum cleaners, video recorders, etc.), office machinery (copiers, Computer hard drives, etc.) and high-tech (atomic energy, nuclear reactors, etc.) and other fields, and are closely related to people's livelihood. Approximately 80% of the world bearing applied to industrial and agricultural machinery, automobiles, trains, aircraft and other transportation equipment. The accuracy of various types of host work, performance, longevity, reliability, and various economic indicators, are closely related with the bearing; in particular, the development of science and technology, all kinds of bearing host made a lot of special requirements, which in turn and promote the development of the bearing industry, development and production of many kinds of special bearings.

In modern society, bearing the world's entire industrial development necessities in the economic development has a very important position. You can drive the world's level of development.
