Detailed Product Description

The National JM207010 wheel bearing race is designed as a taper bearing cup, a critical component in wheel bearing assemblies that supports rotational movement and reduces friction. The cup bore measures 3.7400 inches (94.9960 mm), providing a precise fit for the corresponding bearing cone. The cup length of 0.9250 inches (23.4950 mm) ensures the bearing is properly seated within the hub assembly, while the 0.1000 inch (2.5400 mm) cup radius helps maintain the correct bearing geometry for smooth operation. This part is essential for maintaining driveline integrity and wheel stability in vehicles requiring this specification.

Compatible Vehicle Fitment and Applications

This wheel bearing race is compatible with various makes and models that require a taper bearing cup with these specific dimensions. It is commonly used in automotive driveline and axle assemblies where precise bearing fitment is critical. When searching for a replacement part, referencing the National JM207010 part number will help ensure compatibility with your vehicle’s wheel bearing system.
