Aligning roller bearing is an important mechanical part，Usually used in heavy load, vibration, high speed or high temperature and other harsh working environment,Self-aligning roller bearing is an important mechanical part, often used in heavy machinery, mining equipment, metallurgical equipment and construction equipment and other industries. According to the different use environment and application requirements, self-aligning roller bearings can be divided into the following types: 1. CC series: inner ring bevel and axis line at one point, the outer ring bevel and axis line at the same point, suitable for high speed, heavy load and impact load and other high strength applications 2. CA series: the inner cone and the axis line intersect at a point, the outer cone is small, suitable for high speed, high temperature and frequent vibration applications. 3 MB series: inner ring bevel and axis line at one point, outer ring bevel and axis line at different points, suitable for high speed, vibration and impact load small applications. 4. E series: inner ring bevel and axis line at one point, outer ring bevel and axis line at the same point or different points, suitable for high speed and large amplitude applications. The above are common types of aligning roller bearings. Generally, appropriate bearing types are selected according to the different use environment and application requirements.Aligning roller bearing is an important mechanical part，Usually used in heavy load, vibration, high speed or high temperature and other harsh working environment,
