Steel Deep Groove Ball Bearing 0.39in Bore 1.02in OD 0.31in L, Pkg Qty 100

Overview

This industrial-grade deep groove ball bearing is engineered for high-speed rotational applications requiring precision and durability. Constructed from hardened steel, the unit features a compact design with a 0.39-inch bore diameter and a 1.02-inch outside diameter. The bearing width measures 0.31 inches, making it ideal for space-constrained assemblies. Dual metal shields are integrated to effectively retain lubrication while excluding dust, debris, and other contaminants, ensuring extended service life in demanding environments. Designed for minimal maintenance, these bearings support significant radial loads and moderate axial loads in both directions. The low friction coefficient facilitates smooth operation and reduces heat generation during continuous cycles.

Key Features

Hardened steel construction for superior wear resistance Dual metal shields protect internal components from contamination Pre-lubricated design eliminates need for initial greasing Supports high radial and moderate axial load capacities Low friction operation suitable for high RPM applications Precise dimensional tolerances ensure accurate shaft alignment Sealed design extends maintenance intervals and service life
