618、619系列薄壁深沟球轴承
该类轴承摩擦系数小,极限转速高,结构简单,制造成本低,易达到较高制造精度。尺寸范围与结构形式多样,应用于精密仪表、低噪音电机、汽车、摩托车及通用机械等行业,是机械工业中使用广泛的一类轴承。主要承受径向负荷,也可承受一定量的轴向负荷。当增大轴承径向游隙时,具有一定的角接触球轴承的性能,可以承受径、轴向联合载荷。在转速较高又不宜采用推力球轴承时,也可用来承受纯轴向载荷。与深沟球轴承规格尺寸相同的其它类型轴承比较,此类轴承摩擦系数小,极限转速高。但不耐冲击,不适宜承受重载荷。
深沟球轴承属于不可分离型轴承!这类轴承具有结构简单、工作期间无需经常保养等优点,而且价格相对便宜。是一种使用极其广泛的向心轴承,适用于在高速运转的工况条件下使用。
