For the development of China's Industry, bearing has become a widely used industrial products and the request on bearing's performance also enhanced. But the greatest weakness of China's bearing industry is that we can't produce high tech bearing which is of particular need. So we can only import high tech bearing from other countries, for example, bearing used in auto, machine tools, rail way, petrochemical, textile and metallurgy industries are all imported goods. To produce high tech bearing, numerical control equipment take a very important role. So learning enough technologies on numerical control equipment will be the major task of China's bearing industry. That means technical communication between China and other countries in this area will become frequent.
