/diy/ - Do It Yourself

is there any "standard" way to trap a bearing from both sides?
I need to trap a small 6701 bearing. one side is easy, but how the fuck do i trap it from the second side? i tried various hooks (pic related), but they either brake during first assembly, or break easily when force is applied from other side.
i had an idea of "peening" the plastic around the bearing with warm soldering iron, but i would prefer it if i could easily disassemble them.
