At present, the market environment of cross tapered roller bearings in China is changing, and the policy environment of industrial development is also changing.The government, accustomed to using stimulus to drive growth, is now relying on sweeping reforms to find new impetus for growth.The transformation and upgrading of enterprises used to be promoted by administrative means, but now they are more forced by market forces.
Similarly, in terms of product technology and industrial scale, China's cross-tapered roller bearing industry has made great breakthroughs.In the process of the development of the cross tapered roller bearing industry, China's market has always adhered to innovation and development, and strengthened the technical exchanges with developed countries, which greatly improved the strength of the cross tapered roller bearing industry in China and the market competitiveness of the products.Many influential brands of precision bearings have emerged at home and abroad.Although in recent years, the level of international competitiveness of products has also been improved, but most of them are concentrated in the middle and low end areas. Such products have low added value, and some high precision cross tapered roller bearings still need to rely on imports.
Taking precision machine tool spindle bearing as an example, spindle bearing as the basic accessories of machine tool bearing, its performance directly affects the machine speed, rotation accuracy, rigidity, anti-chatter vibration cutting performance, noise, temperature rise and thermal deformation, etc., and then affects the precision of processed parts, surface quality, etc.For CNC machine tools, machining centers and other high-speed, high precision machine tool spindle support, we need to choose P4 and to the superior ultra-precision bearings.With the rapid development of numerical control technology, "compound, high speed, intelligence, precision, environmental protection" has become the main trend of today's machine tool industry technology development.Among them, high speed machining can effectively improve the machining efficiency of the machine tool and shorten the machining cycle of the workpiece.This requires the machine tool spindle and its related components to adapt to the needs of high-speed machining.At present, the machine tool industry's demand for P4 and its superior ultra-precision angular contact ball bearings is about 150,000 sets, about half of which comes from famous foreign bearing companies such as SKF bearings.n addition to psychological factors and brand effect, the technical performance and reliability of bearings are the main reasons for machine tool customers to choose imported cross-tapered roller bearings.
