 Wheel-End Components


Keeping our customer's vehicles up and running is a critical focus. Maintaining a high fill rate on our Euclid Wheel-End offering gives customers the flexibility to order a part today, and receive it tomorrow. We are also continuously maintaining, reviewing and updating our catalogs to provide you with the best technical expertise and support available.


One of the great challenges for truck and trailer component manufacturers is how to reduce weight without sacrificing strength and durability. Meritor meets this challenge with its Euclid hub, the lightest standard ductile iron hub in the industry.

Pound for pound, Euclid hubs are as strong or stronger than other ductile iron hubs and much more durable than aluminum hubs.


  • Engineered using ductile iron instead of aluminum to provide more than 50 percent improvement in both tensile and yield strength
  • No heating requirements for bearing cup replacement, unlike aluminum hubs, which reduces maintenance time
  • Higher strength threads to significantly reduce the likelihood of stripping which can result in oil leaks and catastrophic bearing failures
  • Expansion rate compatibility with steel bearing cups to help ensure proper fitting
