The pedal bearing unit has a pedal bearing axle (3) connected to the pedal cranks (4,5) and housed rotatable in a housing (2) through two spaced rolling bearings formed as axial inclined needle bearings (8,9) whose bearing needles (8.5, 9.5) have rotary axles (8.7, 9.7) which roll at an angle inclined to a bearing axle on associated tracks between two flat metal washer disc (8.1,8.2, 9.1,9.2). The inclined needle bearings are tensioned against one another through conical contact bearing faces (2.1, 10.1, 11.1) : The flat washer discs are made through chipless shaping and subjected to a hardening process. |
