A pedal bearing for a bicycle comprises a housing for insertion into a sleeve (12) of a bicycle frame. The pedal shaft (5) has two shoulders (7) spaced apart and shaped as rolling-contact races which face opposite races (6) in the housing. Rolling-contact elements (8) are arranged between the races. The rolling-contact races (6) are axially adjustable and lockable to adjust and set the bearing play. The housing consists of two cup-shaped housing parts (1, 2) having their open ends facing and screwed together, the bases (3) of which are shaped to provide the internally coaxially arranged rolling-contact races (6). The housing parts may be of plastics materials, with the rolling contact races of steel (Fig. 2, not shown). A centering bushing (17) is forced against the interior of sleeve (12) by a nut (16). <IMAGE> |
