Steel Deep Groove Ball Bearing 1.38in Bore 3.15in OD, Pkg Qty 10

Overview

This high-performance deep groove ball bearing is engineered to meet the rigorous demands of industrial machinery and heavy-duty equipment. Designed for reliability in challenging environments, it provides exceptional radial load support while maintaining smooth, high-speed rotation. The unit features a robust steel construction that ensures durability under continuous operation. With a precise 1.38-inch bore diameter, a 3.15-inch outside diameter, and a width of 0.83 inches, this bearing fits seamlessly into standard housing configurations. The inclusion of C3 internal clearance allows the component to accommodate thermal expansion and minor shaft misalignments without sacrificing operational stability or efficiency, making it an ideal choice for applications where temperature fluctuations are common.

Key Features

Dual rubber seals effectively retain lubrication and exclude dust, moisture, and other contaminants Hardened steel raceways and balls provide superior wear resistance and extended service life C3 internal clearance design accommodates thermal expansion during high-speed operations Optimized geometry reduces friction and heat generation for energy-efficient performance Precision-machined dimensions ensure easy installation and reliable fitment in standard assemblies Capable of supporting significant radial loads with moderate axial load capacity in both directions
