Bearing Cone
Mack

Bearing cones are a critical component in hub assemblies, providing the inner race support that positions the bearing elements precisely within the housing. A well-made cone maintains proper preload and alignment, reducing heat buildup, wear, and potential seizure under heavy loads and long-haul conditions. The cone’s geometry and material selection contribute to smooth rotation, improved wheel life, and reduced vibration felt through the chassis. When replacing a bearing cone, ensure compatibility with the corresponding cup, race, and seal, and verify proper lubrication channels are unobstructed for optimal performance. Routine inspection can catch pitting or brinelling early, preventing catastrophic hub failure. Source One Parts Center, your reliable source for hub and bearing components.
