I don't know what this is but wondering if anybody knows.

At the top of my closet doors on each door there is a ball bearing
that keeps the door shut
when you close it. Below the ball bearing in the door is a spring.

Does anybody know what this is called and where I can get a
replacement.

It's called a "ball catch" and any big box or hardware store will have it.
