General Information
I do not have the specifics on this, I had purchased it in 1982. The cups  are machined of aluminum and have a seal that buts up against the axle, it uses roller bearings.
There is a bearing cage that set between the center block and the cups. This is tightly machined to where the center aluminum cap (The part that has the bullseye sticker),
sits tightly between the cups without axle play.
