625 Bearing Press for 3D Printer Wheels that use V-slot Grooves
Description
This is an unnecessary tool for changing the bearings in a 3D printers V-slot wheels. I say "unnecessary" because to change the bearings, you really only need a small hammer and a small screwdriver or punch. Place the punch through one side to the middle so it can press the opposite one out (the two bearings each go "out" from the middle of the wheel). Apply _very_ light taps to the inner race, in this case the base part of this was really handy to catch the bearing and the brass or stainless spacer for the inner race. The two bearings are held apart when inside the wheel by a thin "rim" that holds the outer races apart, the inner races are separated by the brass/stainless spacer/shim. If you press both out from one side, you'll eventually have to break this rim, but if you use the taping punch method you can leave the rim intact for you to manually slip in the new bearings... -------------------------- Reviews of replacement wheels seem to have one conclusion: the wheels are fine, but the bearings aren't. So I figured I should have a way of replacing the bearings in replacement (unworn) printer wheels, thus the bearing press. That was before I learned about the inner rim to separate the bearing races. You can use the press as a press with a C-clamp (over 2" size), arbor press, or hydraulic press, but the simple fact is the cylindrical press part is not needed, but the anvil/base is fine as it can capture the pressed out parts. I ended up manually inserting the new bearings in the wheels (clear polycarbonate from Amazon).
