双向推力型
标准系列双向推力球轴承,是专为承受双向轴向载荷而设计的推力轴承产品。其结构由轴圈、座圈、中圈及两组钢球保持架组件构成,其中中圈安装在轴上,两侧分别与轴圈和座圈配合,从而实现双向轴向定位与承载。该轴承可同时承受来自两个方向的轴向载荷,适用于轴需要双向固定且轴向力交替变化的场合。 需特别强调的是,双向推力球轴承不具备任何径向承载能力,在安装和使用过程中必须确保轴与轴承座之间仅存在轴向载荷,不得承受径向力,否则将导致轴承过早失效。该系列轴承结构紧凑,承载能力可靠,安装维护简便,广泛应用于机床主轴、齿轮箱、减速机、泵类及压缩机等需要双向轴向定位且载荷方向经常变化的设备中。GKRW提供标准系列及多种非标设计,可根据用户要求定制尺寸、游隙及材质,满足不同工况需求。如需技术选型或安装指导,欢迎咨询GKRW应用工程师。
