Do you know ZYS Bearing code?
Mar 08, 2018

     Bearings are parts that fix and reduce the load friction coefficient during mechanical transmission. When other parts make relative motion on the shaft, the bearing can be used to reduce the friction coefficient in the process of power transfer and to keep the center of the shaft fixed. According to the different friction mode, ZYS bearing can be divided into rolling bearing and sliding bearing.

     According to the different function, design of bearings, there are many types of ZYS bearings, including ZYS needle roller bearings, ZYS self - aligning ball bearing, ZYS deep groove ball bearings, ZYS self - aligning roller bearing, ZYS thrust bearings, ZYS joint bearings, ZYS combined bearings, ZYS rolling mill bearings, etc.

      A complete bearing code is composed of a base code and one or more supplemental codes. The base code is used to indicate the type of bearing, the basic design of the bearing, dimensions of bearings. Supplementary codes refer to components of bearings that are of different construction or other characteristics from the basic design.
