Unless I am misunderstanding your question, revolving a semi circle will get you a sphere.

I don't know if your company manufactures bearings, but if not, I'd go to the bearing manufactures website and get a CAD model from them.

Or change vendors to someone who would provide CAD models of bearings.

Or just use a Free-Form shape, start a new part, enter Free-Form, select the Sphere, select the work plane and start point, enter your radius, create the Free-Form sphere, then exit the Free-Form.

Although, I question the trueness of the Free-Form Sphere. It's probably more accurate to revolve 1/2 of a circle sketch and get a true sphere.

Or use the Design Accelerator built into Inventor to create your bearing.

The easiest would be to use the "Primitives" supplied with Inventor. Under the "3D Model" model tab simply select the shape required in the "Primitives" tab. By default this tab is turned off when Inventor is installed (knew there used to be a Primitive shapes in Inventor). You need to select the menu drop-down icon (very Right Hand) in the Ribbon Menu and check "Primitives"
