61805TN

The 61805TN 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 low noise, high rotational speed, and smooth operation within a limited installation space. It is specifically designed for small and medium-sized equipment that needs to stabilize power transmission and prioritize the user experience. It retains the compact dimensions of the 61805 series, with an inner diameter of 25mm, an outer diameter of 37mm, and a width of 7mm. The bearing body is made of GCr15 high-carbon chromium bearing steel, and the nylon TN cage is lighter than traditional steel plate cages, which can effectively reduce the friction coefficient and noise during operation, improving the transmission smoothness. It is suitable for equipment that requires stable continuous operation. This bearing can stably withstand radial loads and small bidirectional axial loads. It is compatible with a normal working environment of -30°C to 120°C. The open design allows for the subsequent replenishment of lithium-based composite lubricating grease to extend the service life. Its standardized size ensures strong interchangeability, making procurement and replacement convenient, while balancing practicality and cost advantages. It is widely used in small precision motors, lightweight transmission mechanisms of automation equipment, precision instruments, power tools, high-end models of household appliances, automotive auxiliary parts, etc., especially suitable for precision transmission structures with higher requirements for operation noise and transmission smoothness.
