A hanging slider includes a main body (100), an axle shaft (210), two wheel members (220/230) and a plurality of roller bearings (300). The main body (100) includes a hollow member (110) and a hooking member (130). The axle shaft (210) penetrates through the hollow member (110). The two wheel members (220/230) are arranged on two ends of the axle shaft (210) and are positioned outside of the hollow member (110) respectively. The roller bearings (300) are received inside the hollow member (110); each roller bearing (300) is parallel to the axle shaft (210) and supports between the hollow member (110) and the axle shaft (210); the roller bearings (300) are arranged to circumference the axle shaft (210). With the linear contacts formed among the roller bearings (300) and the hollow member (110) as well as the axle shaft (210), the useful lifetime of the hanging slider is prolonged. |
