The utility model relates to a sealed single-row self-aligning roller bearing and its cage, comprising an outer ring, an inner ring, a drum-shaped roller and a cage made of punched steel. An arc raceway is arranged on the inner circumference surface of the outer ring, an inner ring raceway corresponding to the arc raceway is arranged on the outer circumference surface of the inner ring, and an inner ring rolls. The axial ends of the raceway are provided with a baffle, the drum roller is placed between the arc raceway and the inner raceway, the cage comprises an annular raceway body, the annular raceway body is provided with a pocket hole, a beam is arranged between the adjacent two pockets, and the annular baffle rings on the axial sides of the pockets are provided with annular baffle rings, and the annular baffle rings of the cage include an axially extended baffle ring body and the baffle ring body. Extending to the corresponding position of the retaining edge, the retaining ring body and the outer circumferential clearance of the retaining edge are matched. The retaining ring body is provided with a dust-proof ring body which is turned and extended to the outer diameter and side, and the dust-proof ring body and the outer sleeve ring are sealed and matched. The sealing structure of the cage is adopted to realize the sealing performance of the bearing, and the structure is simple and compact.

密封型单列调心滚子轴承及其保持架
本技术涉及轴承
,确切的说是单列调心滚子轴承及其保持架。
技术介绍
常用标准设计的单列调心滚子轴承,具有单列的调心滚子,主要承受径向载荷,同时也能承受任一方向的轴向载荷。有高的径向载荷能力,适用于重载或振动载荷下工作,其调心性能良好,能补偿同轴度误差。常见的单列调心滚子轴承保持架主要是实体黄铜保持架,特别是中型和大型单列调心滚子轴承保持架也只有实体黄铜保持架。为此,现有对其进行改进设计,增加冲压钢保持架。但现有调心滚子轴承的不具有密封性能,或者密封结构复杂,装配不便。
