on what principle do ball bearings work

Ball bearings are used to convert sliding friction to rolling friction. They are placed between two surfaces which have to move relative to each other. Then, they are in contact with both the surfaces while motion takes place but in stead of sliding, rolling friction is present.

 rolling friction is very  little thus there is no resistance between the walls of the bearings and the tiny metal balls in between them

i agree with saba yawar.  ball bearings are used where rotatory motion is required.  in a ball bearing , the axle rotates on the ball without sliding.

friction can be reduced by using ball bearings or roller bearings in machines. because when a body rolls over a surface, ht eforce of friction is much less than that on a flat surface.

Ball bearings operate on the principle of rolling friction or sliding friction.
