Bearing Cone
Mack

This bearing cone is a critical component in a tapered roller bearing assembly, providing the inner race surface that works with the roller elements to distribute load evenly and maintain correct preload. Proper seating and alignment are essential to preserve bearing life, minimize heat generation, and reduce unwanted vibrations that can affect drive-line efficiency. The cone’s geometry is engineered to complement the corresponding cup, ensuring concentricity and consistent contact under various loads. Regular inspection for wear, scoring, or corrosion is recommended, and replacement should be performed as part of a controlled bearing servicing program. When fitting a new cone, verify compatibility with the cup and shaft to avoid premature failure. Source One Parts Center.
