6310-ZZ Sealed Ball Bearing 50x110x27mm Wholesale GQZ Low Noise Pre-greased Industrial Rotary Equipment Bearing
- 6310-ZZ is a popular medium-heavy load single row deep groove ball bearing with dimensions 50×110×27mm, equipped with double-sided stamped steel ZZ dust shields. The closed metal shield structure effectively blocks dust, sand and dry impurities, perfectly adapting to dry industrial working environments. Pre-filled with long-lasting high-temperature grease at the factory for direct installation without secondary refueling. Its large-size steel balls deliver outstanding radial load bearing capacity and can withstand light bidirectional axial loads simultaneously. Precision polished raceways ensure smooth, quiet and stable medium-speed continuous operation, widely adopted as universal transmission spare parts for various industrial and agricultural mechanical equipment.
