背襯軸承
背襯軸承專用于多輥薄板軋機,用于軋制電力冷軋硅鋼片,汽車工業用優質薄板,鍍層板及不銹鋼板等技術附加值高的薄板。該類軸承本身直接作為支撐輥使用,在結構上外徑壁厚遠遠大于普通軸承,外徑的徑向跳動和組裝后壁厚尺寸的相互差極小。軸承的額定動負荷較大,能在重負荷下進行高精度旋轉。
Backing  bearing
   
      Backing bearing is specially used for thin plate multi-roll mill. It is used to roll technical value added thin plates, such as cold rolling silicon steel plate for electric industry, quality thin plate for automobile industry, coated plate and stainless steel plate, etc. This type of bearing itself serves as a backup roll. In structure its outer diameter wall is much thicker than that of an ordinary bearing. Furthermore, the radial run out of outer diameter and the mutual difference in wall thickness dimensions after assembly are extremely small. The rather high live load rating of the bearing allows high precision rotation under heavy loads.
