The 6804-2RS is a Double Rubber-Sealed Extra-Thin Deep Groove Ball Bearing developed for compact assemblies requiring reliable protection against contaminants. Fitted with two rubber contact seals (2RS) on both sides, it effectively blocks dust, moisture, and fine particles while retaining grease for extended service. With a 20 mm bore and a slim 7 mm width, this bearing is especially suitable for applications where radial space is limited and sealing performance cannot be compromised.
