    1. Step 1

      Open a new part and create the following sketch on a plane.then revolve it around a center axis.

      Medium

    2. Step 2

      this will create the basic outer housing of a ball bearing.

      Medium

    3. Step 3

      on the plane passing through the center make the following sketch. the circle touches the inner curved surface.the number of spokes corresponds to the number of the ball which will be inserted.

      Medium

    4. Step 4

      this will create the following outer housing

      Medium

    5. Step 5

      in a new part we will create the inner housing of the bearing. for that create the following sketch and revolve it around the central axis.

      Medium

    6. Step 6

      for the shaft to have a grip we creates grooves in the inner housing.for that make following sketch and cut it

      Medium

    7. Step 7

      you can make two grooves by using mirror feature(optional)

      Medium

    8. Step 8

      this creates the inner housing for the ball bearing.now its time to create the ball. for that in a new part create a semicircle and revolve it as follows.

      Medium

    9. Step 9

      in the central plane of the ball create the following sketch.this will be helpfull for mating in the assembly.

      Medium

    10. Step 10

      open a new assembly.insert the outer and inner housing in it. mate their respective planes and their central axis to make them concentric and lie in same plane. for this you will require two coincident mates(for making them in same plane and for making them concentric).

      Medium

    11. Step 11

      insert the balls.(i am inserting 8 balls which can vary as your wish)

      Medium

    12. Step 12

      now mate one of the marked point in the all with the arc in the outer housing with the coincident mate..

      Medium

    13. Step 13

      then mate the two axis using coincident mate to align it properly.

      Medium

    14. Step 14

      mate all the balls similarly.

      Medium

    15. Step 15

      hide the excess lines to make it look good.

      Medium

    16. Step 16

      you can also add an animation using this when using this in any further assembly.

    17. Step 17

      important thing is that "radius of the arc created on the outer housing should be equal to the sum of the ball diameter and radius of the inner surface of the inner housing". else the balls will mesh into the housing.

    Also you can use Toolbox and you have all bearings :)
