摘要： PURPOSE: To increase load capacity of a bearing and improve its performance, by cutting off an outer ring raceway bottom, at the side built with balls in a maximum type, toward the side of an end face and forming a cylindrical shoulder part in diameter larger by a prescribed proporation than a diameter of the raceway bottom, in the above described bearing for an automobile axle.
CONSTITUTION: Ball rowsI, II are formed between outer and inner rings 1, 2, and balls 6 are built in the ball rowIto a maximum type. A raceway track 9 of the ball rowIis cut off at a bottom 10 and connected by a right angular line 12 to a cylindrical shoulder part 4 in a diameter dc larger than a diameter of the raceway track by the dimension not less than about 5% from a diameter of the ball 6. In this way, at least one more ball is increased in the raceway track II at the side not applied with a higher load. Thus load capacity in the raceway track II can be increased to about 10%, as a result a calculated life can be increased to about 35%. Accordingly, reliability and performance of a bearing can be improved with an increase of load capacity.
