Skateboard bearing
 
skateboard bearing skateboard bearings
 

Rollerblading, inline skating and skateboarding.  The high precision provides high speed and the convenience of removal shields for cleaning and relubrication. Our skating bearings with their terrific speed and close tolerances. These special bearings are manufactured to the exact ABEC tolerances necessary to bring you absolute speed and durability in your rollerblading and skateboarding endeavors!

It hurts to say this, but skateboarding wouldn’t exist without the invention of roller skates. The first skateboards used roller skate trucks, wheels and bearings in order to operate. I am not sure if their was a standard for roller skate wheels back then, but I imagine that they came in all sorts of shapes and sizes, and I am going to bet that the bearings did too.
A skateboard bearing are comprised of usually twelve parts. They are: inner race, outer race, two shields, and eight balls. Eight skateboard bearings are required to operate a conventional skateboard. Some skateboard bearings include a cage to hold the balls in place.
The balls.

The balls are usually made out of steel? What kind? Are they honed into balls? Are they the same material as the races?
Races:
The races are the “tracks” that the balls roll in. The balls sit in between the inner and outer races. (show diagram). How are races made?
Shields:
The shields cover the innards of the bearings. They are usually made of thin sheet metal. New shield designs have led to rubber and plastic shields. Shields can be removable. Removable shields are a convenient feature for cleaning and maintaining your skateboard bearings.
