638 ZZ RICH 8x28x9

638 ZZ RICH Single Row Deep Groove Ball Bearing – 8 x 28 x 9 mm – Protected by Non-Contact Shields

Experience smooth and reliable rotation in your compact assemblies with the 638 ZZ RICH single row deep groove ball bearing. This precision-engineered radial ball bearing is designed for applications where robust performance and protection are required within a confined space. A key feature is its double-sided non-contact shields (ZZ). These metallic shields act as an effective barrier, diligently protecting the bearing's internal components from the ingress of larger contaminants like dust and debris, while maintaining minimal friction for optimal rotational efficiency. This non-contact design contributes to reduced heat generation and allows for higher speed capabilities compared to contact seals.

With its precisely defined dimensions of 8 mm inner diameter, 28 mm outer diameter, and a concise 9 mm width, this RICH bearing offers versatile integration into a multitude of light to medium-duty industrial and mechanical systems. Its durable steel cage ensures precise ball guidance and contributes to consistent, smooth operation.

Proudly manufactured by RICH in China, this high-quality deep groove ball bearing weighs 0.029 kg. Its combination of effective shielding, compact dimensions, and reliable performance makes it an ideal choice for a wide range of applications across Europe and global markets, from small motors and household appliances to various precision instruments.
