Is there a _small_ gear puller, suitable for pulling a half inch diameter

There are small gear pullers. Bicycle or motorcycle? What's a linear
brake?

linear brake off a bike? Hammering on it would damage its support.
I need something to pull on the outer edge while pushing on the center
shaft, to avoid it.

It's not so much that great force is required but that it be restricted
to the brake component in question.
