Bearing Cone, 2-7/16 in ID
Volvo

This bearing cone, with a 2-7/16 inch inner diameter, is a key element in the hub and wheel-end assembly, providing the correct seating for the roller bearing set. Its geometry supports load distribution across the bearing, enabling smooth rotation and minimizing peak stresses during acceleration, braking, and cornering. The cone works in concert with the corresponding cup to establish the proper preload and alignment, which helps control endplay and runout. By maintaining precise contact surfaces and tolerances, it helps extend bearing life, reduce heat buildup, and lower the risk of seizure or uneven wear under heavy loads. When replacing this component, it’s critical to verify the inner diameter, taper angle, and surface finish match the OEM specification to ensure consistent performance. Proper handling and lubrication during installation further enhance reliability and service intervals. Source One Parts Center.
