628/6

628/6, as a miniature single-row deep groove ball bearing, its core function is to provide a highly adaptable and low-maintenance universal rotating support for various small-sized devices in compact space scenarios. With a small size of 6mm inner diameter, 13mm outer diameter, and 5mm width, it perfectly fits micro mechanical structures with strict installation space limitations. It is made of bearing steel for the rings and balls, combined with a steel cage, featuring a simple structure and durability. It can stably withstand regular radial loads and bidirectional axial loads, meeting the basic load requirements of most small-sized devices. This bearing has a low friction coefficient and, after optimization, exhibits excellent vibration and noise performance, suitable for high-speed rotating conditions of equipment. The 628/6 - 2Z model, with double-sided metal dust-proof covers, can firmly lock in pre-filled lubricating grease and prevent dust and other impurities from entering, significantly reducing maintenance frequency and extending service life. With its universal structural design, stable basic performance and high cost-effectiveness, it is widely applicable to various civilian and industrial scenarios such as miniature motors, precision instruments, small transmission mechanisms, household appliances, electronic equipment and toys, serving as a high-adaptability basic component for achieving smooth rotation in small devices with no extremely high requirements for precision and load.
