61806TN

The 61806TN is a single-row deep groove ball bearing equipped with a polyamide (PA66) nylon cage. Its core function is to serve as a general precision transmission component for general applications that require advanced features such as low noise, high rotational speed, and smooth operation within a limited installation space. It is specifically designed for small and medium-sized continuous operation equipment that needs to balance performance and cost. It retains the compact dimensions of the 61806 series, with a 30mm inner diameter, 42mm outer diameter, and 7mm width. It is suitable for installation scenarios with limited space. The bearing body is made of GCr15 high-carbon chromium bearing steel, and the nylon cage is lighter than traditional steel plate cages, which can effectively reduce the friction coefficient and noise during operation, improve the smoothness of transmission, and reduce component wear to extend service life. This bearing can stably withstand radial loads and small bidirectional axial loads. It is suitable for normal operating environments ranging from -30°C to 120°C. The open design allows for subsequent replenishment of lithium-based composite lubricating grease as needed. The standardized size ensures strong interchangeability, making procurement and replacement convenient. It is widely used in small precision motors, automated equipment lightweight transmission mechanisms, precision instruments, high-end power tools, high-end models of household appliances, automotive auxiliary components, and other scenarios, especially suitable for continuous operation equipment with high requirements for operation noise and transmission smoothness.
