If "BB" means air rifles BBs or ball bearings, then the bucket of "BB" will weight a LOT more than the bucket of dry cottonballs.
ball-bearing i thought it was a size comparision. there a b and bbb sized balls. BB guns shoot small BBS that are normally .177 caliber (4.5mm). a bb is a ball bearing that the gun shoots. the speeds vary from 200-1500 fps (feet per second.)
Faulty ball bearings lead to bearing failure.
Ball bearings are polished by using an abrasive cloth. Before the bearings can be polished, the polishing paste must first be applied to the ball bearing.
If you need replacements, they can be bought at a hardware store. If you mean applications/uses ... bicycle wheels have ball bearings. Lots of rolling objects that move around an axle have either needle bearings or ball bearings or roller bearings.
