61803-Z

61803-Z is a single-row deep groove ball bearing equipped with a single-sided stamped steel plate dust cover. Its core function is to serve as a dust-proof basic transmission component for small and medium-sized equipment. It is specifically designed for general scenarios that require basic cleanliness and need to reduce the interference of impurities. It adopts a standard size of 17mm inner diameter, 30mm outer diameter, and 7mm. The structure is simple and adaptable, and it can easily integrate into the installation structure of most small and medium-sized machinery. The single-sided dust cover can effectively prevent solid impurities such as dust and debris from entering the internal raceway, while reducing the loss of internal lubricating grease and extending the maintenance cycle. The bearing is made of GCr15 high-carbon chromium steel material, which has good wear resistance and fatigue resistance, and can stably withstand radial loads and small bidirectional axial loads. It is pre-filled with lithium-based composite lubricating grease upon leaving the factory, operates smoothly, and is suitable for a normal working environment of -30°C to 120°C. Its specifications comply with international standards, have strong interchangeability, and have controllable procurement and replacement costs. It is suitable for scenarios such as small industrial motors, fans, office equipment, household appliances, automotive auxiliary parts, automation production line accessories, etc., and can ensure the smooth operation of equipment by providing reliable dust-proof effects and stable transmission performance. It is a universal transmission choice that combines practicality, dust-proof requirements, and economy.
