The gap between domestic bearings and import bearings

At present domestic bearing development progress, slowly had formed the industrialization, the world market for about ten percent of the Chinese domestic bearing factory bearing, sales volume occupies the world third. But compared with the imported bearing industrial world powers, domestic bearing still has certain gap. Main show is the high technology, high precision, high value-added products proportion is low, the stability of the products need to further improve and improvement. Now from the domestic bearing and imported bearings of the difference between 1 and the accuracy of bearing, although the size deviation and rotating precision of domestic bearing and imported bearings have been very close. But with SKF bearing imports, there is still a gap on the discrete degree. Foreign research and application of the already 'beating non-repeatable this fine rotation precision index, while China is still blank in this aspect research. 2, in terms of vibration, noise and different tone, Japan has launched silent and silent bearing, China bearing vibration of extreme levels compared with Japan bearings, usually to a difference of more than 10 db. 3, in the life and reliability, deep groove ball bearing, for example, foreign brand products generally for calculating the life of a life of more than 8 times ( Up to 30 times above) , reliability is more than 98% ( Or the pursuit of life, such as host) , and the life of the Chinese bearings are generally only for calculating the 3 to 5 times of life, the reliability is approximately 96%. 4, performance at high speed, the foreign brand products of DmN value up to 4 x 106 mm r/min, while China bearing is only 2 times 106 mm r/min. Although domestic bearing and imported bearings have a lot of difference, but after the Chinese people of must have developed a more high quality bearing products, also can have a lot of excellent bearing enterprise was born.
