<p>PURPOSE:To increase loading capacity by designing the diameter of pitch circles of fitting ports bored in flange members which are extended to inside diameter direction from inner and outer races, to be the same or smaller than pitch circles of rotating bodies. CONSTITUTION:A pair of raceway tracks 2, 3, 5, 6 are formed on each of an outside surface of an inner race 1 and an inside diameter surface of an outer race 4, and balls 7, 8 are fitted between the raceway tracks. Flange part members 9, 10 are extended from the inner and outer races 1, 4 in the inside diameter direction, and mounting ports 11, 12 to mount bearings on other supporting members are made in the flange members 9, 10. Pitch circle diameter (d1, d2) of the mounting ports 11, 12 is designed to be the same with or smaller than the pitch circle diameter (d) of rolling bodies 7, 8. By doing so, the number of the rotating bodies 7, 8 to be fitted can be larger and the loading capacity of the bearing can be increased.</p> |
