一、概述陶瓷滚动轴承是一种新开发的高性能轴承，具有耐高温、耐磨、耐腐蚀及无磁性等优良特性，能够满足多种特殊使用环境的要求。而混合式陶瓷轴承（只有滚动体为陶瓷材料坝u特别适用于高速场合。随着高速磨削及切削技术的发展，正逐渐用混合式陶瓷轴承替代钢制高速机床主轴
First, an overview of ceramic roller bearings is a newly developed high-performance bearings, with high temperature, wear-resistant, corrosion-resistant and non-magnetic and other fine features to meet a variety of special requirements for the use of the environment. The hybrid ceramic bearings (only the rolling material for the ceramic dam u is particularly suitable for high-speed occasions. With the development of high-speed grinding and cutting technology, hybrid steel bearings are gradually replacing steel high-speed machine tool spindle
