Overview
This industrial-grade deep groove ball bearing is engineered to provide robust rotational support for heavy-duty machinery and power transmission systems. Constructed from high-carbon steel, the unit offers superior hardness and fatigue resistance, ensuring reliable operation under significant radial and moderate axial loads. The bearing features a precise 2.56-inch bore diameter and a 5.51-inch outside diameter, with a total width of 1.30 inches to match standard housing configurations. Its double-shielded design effectively retains internal lubrication while preventing the ingress of dust, debris, and moisture, which significantly extends service life in challenging environments. This component is ideal for applications requiring minimal maintenance, precise shaft alignment, and consistent performance over extended operational cycles.
Key Features
High-carbon steel construction for maximum durability and wear resistance Double-shielded sealing mechanism to retain grease and exclude contaminants Optimized raceway geometry for reduced friction and heat generation Capable of supporting heavy radial loads and moderate axial forces Precision-machined dimensions for seamless integration into standard assemblies Low noise and vibration levels during high-speed rotation Extended service intervals due to effective lubrication retention
