Ball Bearing (BB) Ball bearings are engineered to throw the knuckle

weight against specially hardened steel raceways, which ride on

the bearing surfaces. The one-piece cup protects the bearings from

moisture and dust. The cup supports no weight so it is not subjected

to functional friction, pressure or wear. Lateral wear is minimized

because the pin is held against thrust by the hardened steel top and

bottom raceways. The bearing units are securely press-fit to the leaf

knuckle to prevent loss when the hinge is disassembled.
