Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this deep groove ball bearing features an inside diameter of 33mm, an outside diameter of 74mm, and a width of 9mm. Constructed from high-grade polycarbonate, it offers a significantly lower weight compared to traditional steel bearings, making it suitable for weight-sensitive assemblies. The inherent dielectric properties of polycarbonate provide excellent electrical insulation, crucial for preventing electrical discharge or interference in sensitive equipment. Furthermore, its excellent corrosion resistance ensures longevity in environments where chemical exposure is a concern. The ball and raceway geometry is optimized for smooth, low-friction rotational movement, facilitating efficient power transmission.
