61808TN

The 61808TN is a single-row deep groove ball bearing equipped with an engineering plastic mold insert. Its core feature is to be a universal thin-walled bearing that is suitable for small installation spaces, while also achieving lightweight and stable transmission. It is specifically designed to provide reliable basic transmission support for equipment with limited installation space and certain requirements for bearing operation stability and lightweight. It retains the compact thin-walled structure of the 61808 series with an inner diameter of 40mm, an outer diameter of 52mm, and a width of 7mm. It can easily adapt to small and medium-sized equipment with limited space. The engineering plastic mold insert corresponding to the TN code of this bearing not only keeps the bearing's own weight at approximately 0.0325kg, but also comes with performance settings suitable for general scenarios. The rated dynamic load is 4.52kN, the rated static load is 4.1kN, and the grease lubrication limit speed can reach 11000r/min, while the oil lubrication speed can reach 14000r/min. It can stably withstand radial loads and small bidirectional axial loads. During operation, it can maintain low friction and stability. Installation is convenient and maintenance requirements are low. It is widely applicable to basic transmission scenarios in fields such as motors, general machinery, small electric tools, precision instruments, and automotive auxiliary components, and can meet the routine operation needs of ordinary equipment, as well as some working conditions with basic requirements for component lightweight and operational stability.
