Overview
This high-precision steel deep groove ball bearing is engineered to deliver exceptional rotational performance for demanding industrial machinery and mechanical systems. Designed with a 1.38-inch bore and a 2.44-inch outside diameter, the unit provides robust support for radial loads while maintaining accurate shaft alignment. The component features a compact 0.55-inch width, allowing for seamless integration into space-constrained assemblies without compromising structural integrity. Constructed from high-grade steel, this bearing offers superior durability and resistance to deformation under heavy operational stress. Manufactured to P5 precision tolerances, it ensures minimal vibration and noise, making it an ideal choice for high-speed applications where reliability is paramount. The design incorporates dual rubber seals on both sides to effectively retain internal lubrication and exclude dust, moisture, and other contaminants, thereby extending service life in harsh environments.
