The 1641-2RS sealed ball bearing is a compact, high-precision bearing designed for smooth and reliable performance in small mechanical and electrical applications. It features a 1/4” inner diameter (ID), 5/8” outside diameter (OD), and 3/16” thickness, making it a popular size for light- to medium-duty rotational assemblies. Equipped with double rubber seals (2RS), the bearing is protected against contamination while maintaining factory-installed lubrication for long service life. The deep groove ball bearing design ensures low friction, quiet operation, and consistent performance. Manufactured from high-quality chrome steel, the 1641-2RS bearing is commonly used in motors, robotics, RC equipment, tools, and precision assemblies.
