A ball roller swaging tool is used when the bearing is chamfered and the housing has a sharp edge. The tool gradually deforms the housing material onto the chamfer of the bearing thus locking it into place. The design of the ball roller swaging tool is critical as either too much or too little material on the bearing can have adverse effects. It will not be possible to use the housing again unless the hole is reamed and a much larger bearing is used although this is not a common practice with this method.
