A bicycle pedal crank bearing comprises two housing parts (102, 103) which are made pot-shaped, with their mouths directed towards one another, and outer roller races (110) are arranged on the inside of the housing-part bottoms through which the pedal crankshaft passes. The clear width of the housing part (102) adjacent to the pedal crank corresponds at least to the diameter of the adjacent crankshaft shoulder (111) plus double the roller diameter. The bottom bore of the housing part (102) is larger than the maximum pedal crankshaft diameter. A gasket engages into the annular space between the crankshaft (104) and the housing-part bore, and the housing part (102) can be displaced approximately the diameter of the roller out of the position of use towards the pedal crank (105). <IMAGE> |
