Ball Bearing Surfaces: Does the Ball Touch Both Races?

In summary, the balls in a bearing do touch both races and there is some sliding involved due to deformation or angular misalignment. Images can help visualize the concept and balls are typically used for thrust loads.

Do the balls in a bearing actually touch both races? If so, how does the thing turn? Won't the balls be moving in different directions at each race, and therefore dragging against one?

There are two answers. In an ideal bearing, there is no sliding. In all real bearings, there is some sliding, but it is due to the deformation or angular mislaignment.
 

1. How do ball bearings work?

Ball bearings work by reducing friction between two surfaces. The balls inside the bearing roll and distribute the weight evenly, allowing for smoother movement.

2. What is the purpose of a ball bearing?

The purpose of a ball bearing is to support and reduce friction between two moving parts. This helps to increase efficiency and reduce wear and tear on the machinery.

3. Does the ball touch both races in a ball bearing?

Yes, the balls in a ball bearing touch both the inner and outer races. This allows for the weight to be evenly distributed and reduces friction between the two surfaces.

4. What types of materials are used for ball bearing surfaces?

The most common materials used for ball bearing surfaces are steel, ceramic, and plastic. Each material has its own unique properties and is chosen based on the specific application.

5. Are there different types of ball bearings?

Yes, there are different types of ball bearings such as radial ball bearings, thrust ball bearings, and angular contact ball bearings. Each type is designed for specific applications and has different load capacities and limitations.
