Luoyang Bearing Science&Technology Co.,Ltd.

Model Number: 2344 Brand Name: ZYS Key Specifications/Special Features: ZYS double direction thrust ball bearings refer to angular contact thrust ball bearings, which have two dimension series, 2344 and 2347. 2344 series are fit for the small end of taper hole of double row cylindrical roller bearings, with 2347 series for the large end.As for ZYS double direction angular contact thrust ball bearing, one circumferential oil groove and three symmetric lubrication holes are set up in the middle of outer ring. Lubricant is lead into the space between the two-row rolling elements and cage assemblies, thus lubrication will be realized through the rotation of bearing.ZYS angular contact thrustbearings have such advantages as high precision, good rigidity, low temperature rise, high speed and convenient fixing and removing.1). About ZYS companyZYS was formerly known as Luoyang bearing research institute, which was founded in 1958 and was the only first-class comprehensive research institute in China bearing industry. As it became one member of China National Machinery Industry Corporation in 1999, the former institute was transformed into the science and technology enterprise. Then Luoyang Bearing Science & Technology Co., Ltd. was established in 2001. ZYS is a high-tech enterprise, which focuses on the research and development of "high-tech, precise, cutting-edge, specialized and special" bearing products, which are applied to the mainframes of national economic construction in various fields and national defense construction.
