摘　　要：针对滚动导卫的导辊和轴承过早失效而引起的使用寿命低下的问题,分析出其产生原因为导辊的材质和孔型选择不当、轧件尺寸控制不当,导辊冷却质量不好等几方面,通过施行优选导辊、控制料型尺寸、保证充分的冷却等改进措施,有效降低了导辊和轴承的消耗量,降低了生产成本,提高了经济效益。The problem of rolling guide short life due to premature failure of roller and bearing is analyzed and causes are inappropriate roller material and pass selection, improper stock dimension control and poor roller cooling. Improvement measures are taken, such as carefully selecting roller, controlling raw material shape and dimension and ensuring sufficient cooling, in order to effectively reduce roller and bearing consumption, lower production cost and increase economic benefit.
