It is one of the largest comprehensive bearing manufacturing enterprises in China's bearing industry.
As a professional bearing manufacturer, LYC after nearly 60 years of development, has a national technology center, according to user needs, design and manufacture of nine types, various precision levels up to more than 10,000 varieties of bearings and bearings related to special equipment, with aviation engine bearings, rail vehicle bearings, special bearings for major equipment and other core technologies, products are widely used in national defense and military industry, aerospace, wind power generation, The products are widely used in national defense and military industry, aerospace, wind power generation, rail transportation, automobile and motorcycle, mining and metallurgy, engineering machinery, machine tools and motors, etc. LYC is the birthplace of the bearings with the largest processing diameter and the highest degree of precision in China, and is also the production base of the domestic bearings with the widest dimensions, the widest coverage of applications, and the most complete varieties of bearings, and maintains a number of records of China's bearing industry. In particular, LYC has successfully provided supporting bearings for the “Shenzhou” series and the “Chang'e” spacecraft, which demonstrates its strong technical research and development strength.

Wafangdian Bearing Wafangdian is the birthplace of China's bearing industry, where the first bearing of New China was born, so there is “China's hometown of bearings” reputation, “China's Bearing Capital”, bearing this advantageous industry in recent years has been expanding and development, with a large number of bearing manufacturers, can produce 10 types of bearings of more than 40,000 specifications, the products sell well at home and in more than 80 countries and regions. A large number of bearing manufacturers, can produce 10 types of bearings, more than 40,000 kinds of specifications, the products sell well at home and in more than 80 countries and regions, and built a large bearing professional market - Wafangdian Bearing Economic and Trade Center, became the distribution center of bearing products. Casting products are exported to East Asia, Southeast Asia, Australia and North America, known as the Northeast casting base. In the “2009 National Top 100 counties (cities) in the evaluation of economic strength” ranked 27, ranked first in the northeast county (city). With Harbin, Luoyang and known as the country's three major bearing origin, but production and sales are more than the sum of the two.
Strong industrial agglomeration capacity. Wafangdian is an important R & D and production base of China's bearing industry, and is also the largest bearing industry agglomeration area in China. There are more than 600 local bearings and supporting enterprises; more than 260 large-scale enterprises; last year, the bearing industry revenue of 18.8 billion yuan, accounting for 1/5 of the domestic bearing enterprises. products covering 9 types, selling well at home and exported to more than 80 countries and regions. 2009 bearing related enterprises output value of 11.8 billion yuan, accounting for the national industrial output value of bearings of 20.3%.
Abundant human and technical resources. There are 1 national-level technology center and 4 Dalian municipal-level technology centers, mastering core and key technologies. Engaged in the bearing manufacturing industry more than 50,000 skilled workers, bearing industry sales, logistics, processing services related to industry personnel more than 100,000 people, accounting for the total number of employees in the same industry 16.3%.
Wafangdian City, the bearing industry development goal is: by 2015, the bearing industrial output value to reach 50 billion yuan, market share accounted for more than 1/3 of the country, the output value of related industries to reach more than 100 billion yuan, to become “Liaoning's only, China's largest, the world's leading” bearing industry manufacturing base and the national major equipment manufacturing base. To this end, Wafangdian has been fully prepared.
