61805-2N

Model 61805-2N is a single-row deep groove ball bearing equipped with double-sided nylon (PA66) cages. Its core function is to serve as a general precision transmission component that meets the requirements of low noise, high rotational speed, and long-term stable operation in narrow installation spaces. It is specifically designed for small and medium-sized equipment that needs to balance performance and cost. It retains the compact size of the 61805 series, with an inner diameter of 25mm, an outer diameter of 37mm, and a width of 7mm. It is suitable for installation scenarios with limited space. The bearing body is made of GCr15 high-carbon chromium bearing steel. Compared to single-sided nylon cages or steel plate cages, the double-sided nylon cages have less friction during operation, lower noise, and better transmission smoothness. They can stably withstand radial loads and small bidirectional axial loads. It is suitable for normal working environments ranging from -30°C to 120°C. The open design allows for the addition of lithium-based composite lubricating grease to extend the service life. Its standardized size ensures strong interchangeability, making procurement and replacement convenient. It combines practicality and cost advantages and is widely used in small precision motors, lightweight transmission mechanisms of automation equipment, precision instruments, high-end power tools, high-end models of household appliances, automotive auxiliary parts, and other scenarios. It is particularly suitable for continuous operation equipment with high requirements for operation noise and transmission stability.
