Detailed Engineering Specifications

Engineered for reliability and performance, this deep groove ball bearing features an inside diameter of 73mm, an outside diameter of 77mm, and a width of 30mm. The advanced polycarbonate material provides excellent corrosion resistance, is electrically insulating, and offers a lower coefficient of friction compared to traditional metallic bearings. This makes it ideal for environments where moisture, chemicals, or electrical conductivity are concerns. Its lightweight nature also contributes to reduced rotational inertia, enhancing energy efficiency in dynamic systems. The precision manufacturing ensures minimal play and consistent load distribution.
