Bearing Cone
Volvo

A precision component of a tapered roller bearing assembly, the bearing cone serves as the inner race that accepts rolling elements and mates with the cup to form a load-bearing interface. Manufactured to tight tolerances, it helps establish the correct contact angle and preload, translating wheel hub loads into smooth, controlled rotation. In heavy‑duty service, the cone must maintain alignment under thrust, radial, and axial stresses, with lubrication pathways that minimize friction and heat. Worn or mis-seated cones contribute to elevated clearances, uneven tire wear, and accelerated bearing failure. Proper seating and torque during hub rebuilds are essential to extend bearing life and maintain consistent service intervals. The cone’s robust steel or alloy construction resists wear, while surface treatment can improve corrosion resistance in harsh road environments. When replacing bearing components, harmonize cone and cup dimensions to preserve performance.
