Sealed crank bearings
 

It was suggested that I go to a cartridge type of crank bearings when my "old school ones" wear out.

Does the new type last longer?

I was told it takes special tools for those?

Ime they will last a lot longer, maybe 50% more, and require less
maintenance as well. On the down side, when they do go, you replace the
unit, but since even a good one is ~15USD I wouldn't sweat that.

You'll need a bottom bracket removal tool, basically a splined socket,
5-10 USD.

You will need to measure the dimensions of the old one before ordering a
new one, it can look confusing but you need to know thread type, and widths.

Imho, stick to the Shimano ones, cheap, last forever.
