61803TN

61803TN is a single-row deep groove ball bearing equipped with a polyamide plastic cage. Its core function is to serve as a lightweight and highly adaptable transmission component for medium and small-sized precision equipment, specifically designed for scenarios where installation space is limited and low noise and high efficiency operation are desired. It features a standard size of 17mm inner diameter, 30mm outer diameter, and 7mm thickness. It balances installation compatibility and structural compactness. The polyamide cage is lighter than traditional metal cages, which can reduce running resistance and noise. It also has excellent wear resistance and guiding performance, enhancing the overall running flexibility of the bearing. The bearing is made of GCr15 high-carbon chromium steel, which combines excellent wear resistance and fatigue resistance. It can stably withstand radial loads and small bidirectional axial loads. It is pre-filled with lithium-based composite lubricating grease upon leaving the factory, and its open design makes it convenient for subsequent lubricant replenishment. It is suitable for normal operating environments ranging from -30°C to 120°C. Its specifications comply with international standards, and it has strong interchangeability. It can meet the transmission requirements of small industrial motors, precision instruments, office equipment, household appliances, automotive auxiliary components, and small automated mechanisms, which have requirements for smooth operation and noise control. It is an ideal choice for precision transmission that balances lightweight, low noise, and economy.
