Changzhou Yunfan bearing has been specialized in the R & D and production of needle roller bearings for 14 years. Now it can produce a full range of needle roller bearings. Located in Houyu, Wujin, Changzhou, Jiangsu Province, it is a professional manufacturer of a full range of needle roller bearings. The main series are: roller bearing, solid ring needle bearing, combined bearing, inner ring, stamping outer ring needle bearing, plane thrust needle bearing, needle cage assembly and non-standard needle bearing, with more than 3000 different specifications. Products are widely used in construction machinery, machine tools, textile, printing, automatic production equipment and machining center tool library. The company's product specifications are complete, the implementation of mass production, perennial equipped with sufficient stock, to provide you with fast service.

The company has complete technical equipment and first-class production and testing equipment. In 2005 through ISO9000 quality system certification, product quality is stable and reliable. Since the launch of the company's own brand YFB, with excellent product quality and perfect service, it has been well received by customers. 70% of the products are exported to European and American markets and have established long-term cooperative relations with many customers at home and abroad.

In terms of materials, the main body of our bearing is made of high-quality bearing steel: GCr15, and the cage is made of ST12. At the same time, we use salt bath quenching, which is to heat and quench the workpiece with molten salt. The results show that the salt bath heating is faster and better than the ordinary air medium furnace, the decarburization and oxidation loss is smaller, and the heat treatment deformation is smaller because the workpiece is heated in the hanging state.

GCr15 is a kind of high carbon chromium bearing steel with low alloy content. After quenching and low temperature tempering, it has high hardness, uniform structure, good wear resistance and high contact fatigue property.
