61803

Model 61803 is a standard single-row deep groove ball bearing that emphasizes universal compatibility. Its core function is to serve as the basic transmission component for small and medium-sized equipment. It is specifically designed for general scenarios where there are basic requirements for installation compatibility and operational stability. It features a standard size of 17mm inner diameter, 30mm outer diameter, and 7mm. The structure is simple and highly versatile, enabling it to easily adapt to the installation needs of most small and medium-sized machinery. It is made of GCr15 high-carbon chromium bearing steel for the raceway and rolling elements, offering good wear resistance and fatigue resistance. It can stably withstand radial loads and small bidirectional axial loads. The bearing is pre-filled with lithium-based composite lubricating grease upon leaving the factory, ensuring smooth operation and convenient maintenance. It is suitable for normal working environments ranging from -30°C to 120°C. The rotational speed performance meets the basic transmission requirements of various general equipment. It is also compatible with international standard specifications, has strong interchangeability, and the procurement and replacement costs are controllable. Whether it is for general machinery, small and medium-sized motors, fans, water pumps, etc. in industrial equipment, or office equipment, household appliances, automotive auxiliary components and other daily applications, it can ensure the smooth operation of equipment by providing reliable transmission performance and wide adaptability. It is the preferred general-purpose transmission option that combines practicality, economy, and ease of availability.
