ABSTRACT:
A skew contact double row ball bearing and a bearing device for supporting a pinion shaft. The skew contact double row ball bearing enabling the simultaneous contact of a ball row in each row on raceways at a specified contact angle when installed even if a clearance amount is reduced by the fitting of the bearing by preventing the ball bearing from being substantially affected by a change in the assembled width of each row by the fitting of the bearing. The axially double row ball rows are interposed between the raceways of inner and outer rings and at pitch circle diameters different from each other and at contact angles different from each other so that the radial clearance of the ball row with the smaller contact angle is set larger than the radial clearance of the ball row with the larger contact angle.
