The invention relates to the technical field of door and window accessories, in particular to a pulley device and a pulley system.The pulley device comprises a base, a connecting shaft, a rotating bearing arranged on the connecting shaft in a sleeving mode and located on one side of the base, and a supporting bearing arranged on the connecting shaft in a sleeving mode and connected with the base; the inner ring of the supporting bearing and the inner ring of the rotating bearing can rotate in the same direction through the connecting shaft; according to the pulley device, the base and the double-bearing rotating structure with the rotating bearing and the supporting bearing are arranged, the connecting shaft is horizontally sleeved with the rotating bearing and the supporting bearing, and the supporting bearing is arranged in the base, so that rolling of the pulley device is smoother and more natural; the pulley device can also be applied to an environment with an extremely narrow space, so that the inner ring size of the bearing and the shaft diameter of the connecting shaft are increased to the maximum extent, the bearing capacity of the pulley device is effectively improved, and then the stability and durability of the pulley device are enhanced.
本发明涉及门窗配件技术领域，特别是一种滑轮装置及滑轮系统，包括基座、连接轴、套设在连接轴上并位于基座一侧的转动轴承、以及套设在连接轴上并与基座连接的支撑轴承；且支撑轴承的内圈能够通过连接轴与转动轴承的内圈同向转动；通过设计一种滑轮装置，其通过设置基座以及具有转动轴承和支撑轴承的双轴承转动结构，并通过将转动轴承和支撑轴承水平套设在连接轴上，并将支撑轴承设置在基座内部，不仅使得滑轮装置的滚动更加顺滑、自然，还能够应用于极窄小空间的环境中，以在最大程度上加大轴承的内圈尺寸和连接轴的轴直径，从而有效提高滑轮装置的承重能力，进而增强滑轮装置的稳定性和耐久性。
