The invention belongs to the technical field of door and window hardware fittings, and relates to an extremely narrow pulley, a pulley device and a door and window, the extremely narrow pulley comprises a pulley body, a bearing and a connecting shaft, and the pulley body is mounted on the connecting shaft; the bearing is rotatably arranged on the connecting shaft in a sleeving manner and is positioned outside the wheel body; the wheel body can rotate in the same direction with the inner ring of the bearing through the connecting shaft. According to the extremely-narrow pulley, the bearing is arranged externally, so that a technician is not limited by the size of the bearing when manufacturing the pulley body, the size of the pulley body is further reduced, and the size of the extremely-narrow pulley is reduced; on the other hand, when a technician installs the extremely narrow pulley, the pulley body only needs to be installed between the door and window and the door and window frame, and the bearing can be installed outside the space between the door and window and the door and window frame. Therefore, the extremely-narrow pulley can be applied and mounted on doors and windows with extremely-narrow spacing, so that the requirements of users are met.
本发明属于门窗五金配件技术领域，涉及一种极窄滑轮、滑轮装置及门窗，极窄滑轮包括轮体、轴承以及连接轴，轮体安装于连接轴上；轴承可转动套设于连接轴上，并位于轮体的外部；其中，轮体能够通过连接轴与轴承的内圈同向转动。该极窄滑轮通过采用轴承外置的方式，一来能够使技术人员在制作轮体时，不受轴承尺寸的限制，进一步缩小轮体的尺寸，即减小极窄滑轮的体积；二来技术人员在安装极窄滑轮时，只需把轮体安装于门窗和门窗框之间即可，轴承可安装于门窗和门窗框之间以外的地方。由此，该极窄滑轮能够应用安装于极窄间距的门窗上，从而满足用户的需求。
