    • PURPOSE: A sealing part of a rolling bearing is provided to improve sealing efficiency, and to reduce sealing friction at high RPM by decreasing initial sealing stress owing to centrifugal force in increasing RPM. CONSTITUTION: A rolling bearing(1) for a clutch disengagement unit for a motor vehicle clutch, comprises an outer bearing ring(2) and an inner bearing ring(3), an inner chamber, a bearing ball(5) and disengagement levers. The outer bearing ring is surrounded by a primary leg(12.1) of a sealing cap. A secondary leg(12.2) is directed radially inward and combined with a plate seal(13) with a sealing lip that runs along the inner bearing ring. The sealing lip is bent outward or inward in the axial direction in the end for the fixed bearing ring, and the plate seal is pressed between the second leg of the outer rotating ring and the front by axial stress at initial stage.
    • 目的:提供一种滚动轴承的密封部分,以提高密封效率,并通过减小由于增加RPM的离心力引起的初始密封应力,降低高RPM时的密封摩擦。 构成:用于机动车辆离合器的离合器分离单元的滚动轴承(1)包括外轴承环(2)和内轴承环(3),内室,轴承球(5)和分离杆。 外轴承环由密封帽的主支腿(12.1)包围。 副腿(12.2)径向向内指向,并与具有沿内轴承环延伸的密封唇的板密封件(13)组合。 密封唇在固定轴承环的端部沿轴向向外或向内弯曲,并且板密封件在初始阶段通过轴向应力在外旋转环的第二腿和前部之间被按压。
