The cup and cone bottom bracket, ususally used on these bikes, consists of fixed cup, the drive side cup, the adjustable cup on non-drive side and cage bearings.

bike bearings brand story

Reviewed in the United States on October 4, 2023
My ancient big box store bike finally had started to develop bearing issues. I got these to replace them, and they fit, but the bearing from the factory had 11 balls, this one only has 7. As such I don't expect them to last as long, which I suppose is ok since I have a spare set, but still kind of a pain to know I may have to tear everything apart sooner.
