Abstract
A cage for a ball bearing, having a front face with cells adapted to hold a row of balls, and a rear face including a ring-shaped body with slots. The slots are adapted to interlock with slots of a second cage. The slots have teeth that extend towards the front face and separate the cells, and the teeth have sides with semispherical bearing surfaces oriented towards a center of a respective cell. The front face includes a closing ring linking the teeth, were the closing ring is adapted to be recessed in relation to an axial extremity of the balls. Additionally, a bearing is provided that includes an outer bushing, an inner bushing, a row of balls, and a cage configured to receive the row of balls, where the cage and the row of balls are received between the outer and inner bushings.
