The Process

The UNASIS Reverse Tri-Roller Swaging Tool is utilised with a v-groove housing and chamfered bearing. The tool works as an inverse of the main tri-roller swaging method. The housing is swaged onto the bearing, rather than swaging the bearing onto the housing. It is essential that correct tool is selected, as you get one attempt to install the bearing. Furthermore, if the bearing is inaccurately installed, the housing may be damaged to the point where it cannot be repaired.
