The 6306-2RS is a robust, high-precision single-row deep groove ball bearing engineered for exceptional endurance in medium-to-heavy mechanical setups. Unlike metal-shielded models, this bearing is equipped with synthetic rubber seals (2RS) on both sides, which are securely bonded to the outer ring to form a reliable contact seal against the inner ring. This design offers superior defense against water splashes, moisture, and fine dust particles while effectively retaining the internal factory grease. Featuring standard metric dimensions—a 30 mm bore, 72 mm outer diameter, and 19 mm width—the 6306-2RS serves as a highly dependable component for electric motors, agricultural equipment, and heavy industrial machinery.
