Bearing Cone
Volvo

This bearing cone is a precision inner race element of a hub bearing assembly, engineered to maintain correct geometry with the mating cup and rolling elements. Correct tolerances support proper preload, seat alignment, and lubrication pathways, all of which contribute to smooth rotation, reduced friction, and extended bearing life. In heavy trucks, hub assemblies endure heavy loads and road shocks, making the cone’s integrity critical to preventing excessive play and heat buildup. Replacement requires attention to matching cone and cup sizes and re‑torquing per spec to ensure consistent performance. Material selection and surface finish enhancements resist wear and corrosion in severe operating environments. When performing hub service, inspect both cone and cup surfaces for scoring or spalling and replace as a matched set to avoid misalignment.
