Steel Deep Groove Ball Bearing 1.38in Bore 3.94in OD, Pkg Qty 8

Overview

This industrial-grade deep groove ball bearing is engineered to deliver exceptional performance in high-load mechanical systems. Constructed from premium hardened steel, the unit offers superior durability and resistance to wear under demanding operational conditions. With a precise 1.38-inch bore diameter and a 3.94-inch outside diameter, it ensures accurate shaft alignment and stable rotation. The compact 0.98-inch width allows for integration into space-constrained assemblies without sacrificing radial load capacity. Designed for longevity, this bearing minimizes friction to reduce heat generation and energy consumption, making it an ideal choice for continuous-duty applications in heavy machinery, electric motors, and power transmission equipment.
