ZYS rotary table bearings are axial/radial cylindrical roller bearings, are composed of two thrust roller bearings and a radial cylindrical roller bearing with the combination of axial and radial preload. For the convenience of transportation and mounting, use two or three symmetrical fixing screws to fasten the two shaft washers in order to prevent collision between rolling elements and rings, and avoid bad influence on bearing accuracy. This kind of bearing can support great radial and axial pressure and overturning moment with high rigidity, so it is especially used for large rotary table and large turntable.
ZYS 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. It was listed at Shenzhen Stock Exchange with stock code 002046 in 2005.
