轴承广泛应用于矿山机械、精密机床、冶金设备、重型装备与高档轿车等重大装备领域和风力发电、高铁动车及航空航天等新兴产业领域。中国生产的轴承主要为中低端轴承和小中型轴承，表现为低端过剩和高端缺乏。与国外相比，在高端轴承和大型轴承方面存在较大差距。
Bearings are widely used in mining machinery, precision machine tools, metallurgical equipment, heavy equipment, high-grade cars and other major equipment fields, as well as wind power generation, high-speed rail cars, aerospace and other emerging industries. The bearings produced in China are mainly middle and low-end bearings and small and medium-sized bearings, which are characterized by low-end surplus and high-end lack. Compared with foreign countries, there is a big gap between high-end bearings and large bearings.
中国高速铁路客车专用配套轮对轴承全部需要从国外进口。在航空航天、高速铁路、高档轿车及其他工业领域用的关键轴承上，中国轴承在使用寿命、可靠性、Dn值与承载能力等方面与先进水平存在较大差距。
All the bearings of the special wheel sets for high-speed railway passenger cars in China need to be imported from abroad. In the key bearings used in aerospace, high-speed railway, high-grade cars and other industrial fields, there is a big gap between China's bearings and the advanced level in terms of service life, reliability, DN value and bearing capacity.
