Bearing Cone
Mack

This bearing cone forms the inner race in a tapered roller bearing assembly, providing the essential seating surface for rollers and a path for load distribution. Proper seating and alignment minimize heat generation and uneven wear, extending bearing life and ensuring smooth operation at higher speeds and loads. The cone’s geometry is matched to the corresponding cup to preserve required preload and contact pattern. Routine inspection for wear, pitting, or corrosion is advised, with replacement as part of a comprehensive bearing service program. Correct installation is critical to prevent misalignment and noise.
