Title: Preloaded double row spherical roller bearing

Abstract: A double row spherical roller bearing has a pair of inner races formed on a unitary member and a pair of outer races formed on spaced apart ring members. A housing with an internal nut received therein forms an annular channel to embrace the split outer race ring members. A spring is mounted between one leg of the channel and one race ring member to exert an axial preload force on the ring members. A pair of spring members is mounted between the outer race members to constitute a restoring force and cushion the outer race members.
