Extended Inner Ring Ball Bearings
Extended inner ring ball bearings are also called extended inner ring bearings or wide inner ring bearings,it is ball bearings with a extended inner ring,they mean the width of inner ring is longer than the width of outer ring in extended inner ring bearings, they are designed for special applications. Usually, the extended inner ring ball bearings or wide inner ring bearings are specially designed to replace the need for additional locational flange in applications.Establihsed in 2007,Zhangzhou Runstar Bearings Manufacturing Co.;Ltd is a professional extended inner ring ball bearings manufacturer in China, we have has a full dimention of extended inner ring ball bearing or wide inner ring bearings for choices, with or without flange at request.Runstar has the material of chrome steel,stainless steel or hybrid ceramic for extended inner ring ball bearings or wide inner ring ball bearings for choice, the most pop in market for extended inner ring ball bearings is with stainless steel
Extended inner ring ball bearings are also called extended inner ring
bearings or wide inner ring bearings,it is ball bearings with a extended inner
