Bearing Cone 89.97mm ID
Mack

The bearing cone is a critical inner race component in tapered roller bearings used in heavy duty hub assemblies. With an inner diameter of 89.97 mm, this cone sets the bearing preload and helps control clearance between the cone and the race. Precise machining and a smooth finishing process minimize friction and heat buildup, extending hub life and improving wheel end performance under load. Proper preload and alignment reduce uneven tire wear and heat related failures that can escalate into service outages. The cone is designed for reliable seating in the race and works in harmony with the bearing cup to maintain stable rotation and load distribution. Regular maintenance and correct installation practices are essential to retain hub reliability. Provided by Source One Parts Center.
