The 618/8-ZZ RICH is a precision-engineered miniature ball bearing built to deliver smooth and reliable performance in compact and high-speed environments. With its slim 8 x 16 x 4 mm profile, it's the ideal choice for applications where both space-saving design and dust protection are key.
Equipped with ZZ metal shields on both sides, this bearing is protected from contaminants while maintaining low friction during operation. The steel cage ensures optimal alignment of the rolling elements, and the CN clearance provides stable operation under normal loads and speeds.
Produced by RICH in China, the 618/8-ZZ is commonly used in small motors, RC models, dental and precision tools, and light mechanical assemblies requiring both radial and limited axial load support.
