61804

61804 is a single row deep groove ball bearing. Its core function is to serve as a universal high-speed, low-noise transmission component that is suitable for compact installation spaces. It is specifically designed for medium-sized equipment with high rotational speeds, medium loads, and a preference for low maintenance. With its compact structure and stable performance, it becomes a fundamental transmission component for various small and medium-sized mechanical devices. It features a small size of 20mm inner diameter, 32mm outer diameter, and 7mm width, and is manufactured with bearing steel or stainless steel. It is paired with a steel plate stamping cage, featuring a simple structure and controllable manufacturing cost. It also has low friction characteristics, can meet the requirements of high rotational speed operation, and can simultaneously withstand radial loads and small bidirectional axial loads. Some specifications have a slight offset adjustment capability of 2′ - 10′, ensuring normal operation even with minor installation deviations. This bearing is mostly of an open design, facilitating the replenishment of lubricating grease as needed to extend its service life. Its standardized size makes it highly interchangeable, and the procurement and replacement are very convenient. Its application scenarios are very extensive. It is suitable for the transmission structure of small industrial motors and household appliances, and can also be used in automotive auxiliary components such as electric tools, car generators, and cooling fans. At the same time, in lightweight transmission mechanisms of automated equipment, precision instruments, and dental mobile phones (which have high requirements for operating noise), it can play a role due to its stable transmission performance and low noise advantage.
