Document Type and Number:

Japanese Patent JP2009063160

Kind Code:

Abstract:

To enable prevention of wear of the inner diameter surface of an aluminum alloy housing without degrading the strength of the outer ring or assemblability thereof to the housing.

Copper plating 7 is applied on the outer diameter surface of the outer ring 3 which is internally engaged with the inner diameter surface of the housing made of aluminum alloy. Because of this, the wear of the inner diameter surface of the aluminum alloy housing can be prevented without degrading the strength of the outer ring 3 or assemblability to the housing even when creep occurs.
