Ball bearing

In SolidWorks, making a ball bearing is pretty straightforward and fun. First, the inner and outer rings are created using a revolve feature, with small grooves to hold the balls. Then, the balls are modeled as spheres and arranged evenly using the circular pattern tool. After that, everything is assembled together, and mates are applied to show the smooth rotation. It’s a simple part but really useful to understand how bearings reduce friction and allow free movement in mechanical assemblies.
