ABSTRACT:
A bird cage having a roller bearing imposed between the axle casing and the bird cage frame. The roller bearing may be sealed to effectively alleviate the problem of dirt accommodation interfering with the rotational action of the axle casing with respect to the bird cage frame. The inside of the roller bearing may be attached to the outer surface of the axle tube or casing to alleviate side play, a sliding motion of the bird cage with respect to the axle casing. This provides a more predictable and freer suspension. The bird cage design may be modular to allow the adaptation of the bird cage to different suspension configurations and to allow for the replacement of damaged parts.
