Overview
This industrial-grade deep groove ball bearing is engineered for high-performance rotational applications across a wide range of machinery. Constructed from premium hardened steel, the unit delivers exceptional durability and dimensional stability under demanding operating conditions. The design features a precise 1.772-inch bore diameter and a 3.937-inch outside diameter, with a compact width of 0.984 inches to fit standard housing configurations. Double metal shields are integrated into the assembly to effectively retain internal lubrication while excluding dust, debris, and other contaminants. This shielding method ensures reliable operation without introducing additional rotational friction, making it ideal for high-speed environments. The bearing supports significant radial loads and moderate axial loads in both directions, providing versatile functionality for motors, gearboxes, pumps, and general industrial equipment. Sold in packages of two, these units offer consistent quality and extended service life for maintenance teams and original equipment manufacturers.
