The two-piece thrust water comprises a raceway portion having a radially directed raceway for rollers and a non-raceway portion extending radially outward from the raceway portion for engagement with a piloting surface. It has mechanical devices, formed integrally on the raceway and non-raceway portions, for joining the raceway portion and the non-raceway portion together. The raceway portion is made of a bearing quality steel and is heat treated. The non-raceway portion is made of a material other than heat-treated bearing quality steel. |
