Abstract

The axle (1) has flanges which separate the central portion from the axle bearings. the crank side of the axle has a sleeve (21) which serves as the inner race for needle and thrust bearings. The needle bearings (22) are located by a cage (23), the thrust bearing being located by the cage (26). The outer race (27) is located in the housing (30). The housing has an external thread by which it is fixed to the cycle frame. A dust seal (36) is fitted to the outer end of the housing. The opposite end of the axle is similar without the needle bearings.
