61805TN-RZ

61805TN-RZ is a single-row deep groove ball bearing that integrates polyamide (PA66) nylon cage and RZ type low-friction non-contact seal. Its core positioning is to be a general precision transmission component with comprehensive requirements for low noise, high rotational speed, dust prevention, and smooth operation in a narrow installation space. It is specially designed for small and medium-sized continuous operation equipment that needs to balance sealing protection and operational performance. 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 and features a bearing body made of GCr15 high-carbon chromium bearing steel. The nylon cage can reduce operating friction and noise, while the RZ type seal structure can effectively prevent dust and impurities from entering without affecting high rotational speed performance. It also reduces lubricant leakage and extends the maintenance-free period. This bearing 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 bearing is pre-filled with lithium-based composite lubricating grease upon factory production, and the standardized size ensures strong interchangeability. Procurement and replacement are convenient, and it combines practicality and protective advantages. It is widely used in small precision motors, automation equipment lightweight transmission mechanisms, precision instruments, high-end electric tools, high-end models of household appliances, automotive auxiliary components, and other scenarios, especially suitable for enclosed or semi-enclosed installation environments with high requirements for operating noise, transmission smoothness, and dust protection.
