Roller bearing sealing assembly

According to one aspect of the present disclosure, a rotor for a railway roller bearing seal assembly is provided. The rotor includes an annular body rotatable about a central axis and including a radially inner ring and a radially outer ring. The annular body includes an intermediate portion connecting the radially inner ring and the radially outer ring and separating the radially inner ring from a base of the annular body in a first direction. The annular body further includes a pocket at least partially formed by the intermediate portion, and a snap-fit portion axially between the base and the free end of the radially inner ring. The snap-fit portion of the annular body is configured to form a snap-fit connection with a snap-fit member of an oil slinger extending into the pocket. 根据本公开的一个方面，提供了一种用于铁路滚子轴承密封组件的转子。该转子包括可绕中心轴线旋转并且包括径向内环和径向外环的环形主体。该环形主体包括连接径向内环和径向外环并在第一方向上将径向内环与环形主体的基部隔开的中间部分。环形主体还包括至少部分地由中间部分形成的凹穴，以及轴向地位于基部和径向内环的自由端部之间的卡扣配合部分。环形主体的卡扣配合部分被构造成与延伸到凹穴中的抛油环的卡扣配合构件形成卡扣配合连接。
