Overview
This industrial-grade deep groove ball bearing is engineered to deliver reliable rotational support for a wide range of heavy-duty machinery and mechanical systems. Constructed from high-quality steel, the unit features a precise 1.57-inch bore diameter and a 3.15-inch outside diameter, with a compact width of 0.71 inches to fit within space-constrained assemblies. The design incorporates dual rubber seals on both sides of the raceway, which effectively retain internal lubrication while excluding dust, dirt, and moisture. This sealing configuration significantly extends service life in demanding environments where contamination is a primary concern. Capable of accommodating both radial loads and moderate axial loads in either direction, these bearings ensure smooth, low-friction operation across varying speeds. Supplied in bulk packages of 50 units, this solution provides consistent performance and cost efficiency for high-volume maintenance, repair, and original equipment manufacturing applications.
Key Features
Dual rubber seals for superior contaminant exclusion and lubrication retention High-strength steel construction for enhanced durability and load capacity Optimized to handle combined radial and moderate axial loads Precision-ground raceways ensure smooth rotation and reduced vibration Compact 0.71-inch width suitable for tight mechanical clearances Bulk packaging of 50 units ideal for large-scale inventory management Compatible with standard industrial shafts requiring a 1.57-inch fit
