    If you modeled everything in position, in your part studio, use a group mate.

    if you want the inside race, outside race, and balls to rotate independently for realism sake read below this line:
    --------------------------------------------------------------------------------------------------------------------------------------------------------
    (I don't recommend unless your playing around, or trying to learn)

    in your part studio:
    add a mate connector to the front face of the race, and make it's OWNER the keeper ring.

    in your assembly:
    1 fix the outside race in the assembly
    2 add a revolute mate to the flat face of the inner race to the flat face of the outer race
    3 add a group mate and select  the ball and keeper ring
    4 add a revolute mate using your (mate connector of the keeper ring) and the flat face of either race
    5 make a circle pattern of your balls using either bearing race as your axis
    6 use gear relation and select your inner race revolute mate and your keeper plate revolute mate, and set up it's ratio

    again this is a lot of wasted effort unless you want to see a working bearing to play around with...

    Nice explanation @john_mcclary

    I know we have "Model Of The Month" but can I vote for this as "Thread Title Of The Month"?
