Combine roller bearing cones with tapered roller bearing cups to create tapered roller bearings that allow you to carry maximum combinations of radial and thrust loads simultaneously.
Tapered roller bearing cones are the bearings minus the cup or race.
In typical modern bikes the bottom bracket spindle is separate from the cranks.
This is known as a three piece crankset.
If the cones are screwed on too far they exert pressure on the bearing balls.
Regular servicing can extend their life although they will.
The cups are built into the shell of the hub.
This will purposely make the bearing adjustment too loose.
Earlier three piece cranks consist of a spindle incorporating bearing cones facing out a fixed cup on the drive side an adjustable cup on the non drive.
