Be careful when working with bearings to not destroy them while trying to remove them from a gearbox/install them into the gearbox. Hit the outer ring so make sure that you don't hit only the inner ring or the balls with the tool.
This is a punch I made to remove bushing and bearings from an airsoft gearbox. It can also be used to install them in.
I used it once and it worked as intended.
The tool is 21.0 mm high, the punch itself has a diameter of 7.8 mm and it has a base with a diameter of 10.0 mm.
Update 12/04/23 : Added a part that is inserted into the bushing/bearing hole, so that the punch doesn't slide off when working. I also put a pattern on the body of the punch so that it can be held more easily.
New size: The tool is 22.2 mm high, the punch itself has a diameter of 7.9 mm and it has a base with a diameter of 10.0 mm.
