Overview
This industrial-grade deep groove ball bearing is engineered to deliver exceptional reliability in demanding mechanical environments. Constructed from high-quality steel, it provides superior resistance to deformation and wear under continuous operational stress. The unit features a precise 1.77-inch bore diameter, a 3.94-inch outside diameter, and a width of 0.98 inches, ensuring seamless integration into standard machinery housings. Designed to support significant radial loads while accommodating moderate axial forces in both directions, this bearing optimizes performance for rotating shafts. The double-sealed configuration effectively retains internal lubrication while excluding dust, moisture, and other contaminants, significantly reducing maintenance intervals and extending total service life in harsh conditions.
Key Features
High-carbon steel construction for maximum durability and load capacity Double-sealed design prevents lubricant leakage and contaminant ingress Precision-ground raceways ensure smooth rotation with minimal friction Supports high radial loads and moderate axial loads in both directions Dimensional stability maintained under extreme thermal and mechanical stress Pre-lubricated for immediate installation and reduced initial maintenance Corrosion-resistant surface treatment enhances longevity in varied environments
