Bearing Cone, 89.97 mm ID
Mack

This Bearing Cone, with an inside diameter of 89.97 mm, is engineered for robust wheel-end support and precise alignment within hub assemblies. The cone interfaces with bearings to maintain correct preload and radial positioning, which minimizes play and reduces heat during high-speed operation. Its surface finish and dimensional tolerances are designed to resist wear and accommodate high-load scenarios common in heavy-duty trucking. Proper installation ensures stable wheel rotation, extends bearing life, and helps prevent premature hub failure. This cone is a critical component for maintaining reliable braking and steering performance on long-haul routes. Source One Parts Center.
