Patent ID: 7597482

Claim:
A skew contact double row ball bearing installed in an apparatus, comprising: an inner ring having first and second inner ring raceways; an outer ring having first and second outer ring raceways; first and second rows of balls spaced axially apart and interposed respectively between said first inner and outer ring raceways and said second inner and outer ring raceway of inner and outer rings; said first and second rows of balls being disposed at different pitch circle diameters and different contact angles from each other; and said inner and outer rings in a predefined orientation relative each other in an uninstalled state defining a first radial clearance in one of the first and second rows of balls in which the contact angle is smaller and a second radial clearance in another one of said first and second rows of balls in which the contact angle is larger, said inner and outer rings in a predefined installed orientation relative each other as installed in said apparatus defining the contact angles of said first and second rows of balls, and said first radial clearance being larger than said second radial clearance.
