一种防尘效果好的深沟球轴承组件 技术领域
 本实用新型属于轴承技术领域，涉及一种防尘效果好的深沟球轴承组件。
 背景技术
 深沟球轴承原名单列向心球轴承，是应用最广泛的一种滚动轴承。其特点是摩擦阻力小，转速高，能用于承受径向负荷或径 向和轴向同时作用的联合负荷的机件上，也可用于承受轴向负荷的机件上， 例如小功率电动机、汽车及拖拉机变速箱、机床齿轮箱，一般机器、工具等。其中轴承座是轴承的配套组件，用于限制轴承的位置，同时便于轴承与其他结构的装配，但在实际应用过程中，受其他因数影响，可能需要将轴承设置在边角或角落，导致常规的轴承座无法满足装配需求，或者装配麻烦，同时由于边角和角落处杂质清理不便，相比其他装配位置杂质更容易堆积，可能导致杂质进入轴承座内，从而加剧磨损，影响轴承组件的使用寿命。
