What is bearing race?

A bearing race is a hardened ring that serves as a raceway for the rolling elements of a ball or roller bearing. It is typically made of steel and is designed to provide a smooth surface for the rolling elements to move along.

Bearing races are usually mounted onto shafts or inside housings, and can be used in various applications such as automotive, industrial machinery, and aerospace. They are an essential component of most types of bearings, helping to reduce friction and distribute the load evenly across the rolling elements.

There are different types of bearing races, including inner races, which are mounted onto shafts, and outer races, which are mounted inside housings. Some bearing races are integrated into the bearing assembly, while others are separate components that can be replaced if necessary.

Overall, bearing races play a critical role in the performance and longevity of bearings, ensuring smooth operation and efficient load distribution.
