Abstract: A bicycle sealed bearing kit is used to install sealed bearing units on a bicycle having a one-piece crank. The kit includes an inner race formed of a cylindrical collar having a flange formed at one end thereof. The flange is integrally formed with the collar and extends outwardly in a plane perpendicular to the collar. The inner race has threads on the inner surface thereof for enabling the inner race to be secured to the crank. The sealed bearing unit is mounted on the collar with one thereof juxtaposed with the flange of the inner race.
Abstract: A bearing assembly and method of installing such within an enclosing open walled chamber wherein the bearing assembly utilizes first and second spaced apart bearing units. The bearing units low frictionally rotationally support a crank. The inner races of the spaced apart bearing units are connected together through a sleeve which is located about the crank. Mounted on the outer race of each bearing assembly is an expanding ring assembly. Each expanding ring assembly can be moved into tight engagement with the wall of the chamber.
