Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this deep groove ball bearing features a 72mm inside diameter, a 121mm outside diameter, and a 37mm width. Constructed from premium 316 stainless steel, it offers exceptional resistance to corrosion, oxidation, and chemical attack, making it ideal for marine, food processing, chemical, and other harsh industrial settings. The martensitic microstructure of the 316 stainless steel provides inherent hardness for load-bearing capacity while maintaining its integrity in aggressive media. Its sealed design (if applicable) further protects against contaminants, ensuring sustained operational efficiency and reduced maintenance.
