Bearing Cone
Volvo

Bearing cone is the inner race segment of a tapered roller bearing assembly and plays a pivotal role in supporting radial and axial loads in the wheel hub and drivetrain. Correct seating and preload of the cone ensure smooth rotation, optimal misalignment tolerance, and long service life for rotors, hubs, and axles. The cone’s precision machining, dimensional stability, and proper lubrication pathways reduce friction heat and guard against wear-induced noise. In many Volvo applications, the cone works in concert with the bearing cup to maintain correct spacing and load distribution across the bearing set, which translates into stable handling, reduced tire wear, and consistent brake drum wear. Replacement requires matching the cone angle, bore size, and race type to avoid premature failure or vibration. Keep an eye on signs of overheating, pitting, or looseness during routine inspections. Source One Parts Center emphasizes using OEM-specified bearings to ensure correct fitment and preload.
