Abstract: A roller bearing system comprising a rolling element having a cylindrical outer raceway; said rolling element is housed inside an outer ring to the bearing system; said outer ring having an inner and an outer diameter surface, is connected to a rotatable shaft from one end, said inner diameter surface of the outer ring having a non-symmetric convex shaped profiling facing the rolling element to facilitate maximum contact area during any operational condition.

Abstract: A valve actuator assembly includes an axially moveable valve and a ramp roller thrust drive. The ramp roller thrust drive includes at least first and second opposed thrust plates, each plate including one or more ramps. A roller is positioned between corresponding opposed plate ramps and a rotation of one of the thrust plates relative to the other thrust plate causes the plates to move axially relative to one another such that axial motion is imparted to the valve.

Abstract: A gear assembly includes a gear having a cylindrical inner bore. A sleeve having a convex inner bearing surface is positioned within the gear bore and a shaft is positioned within the sleeve inner bearing surface. A plurality of rollers are positioned between the shaft and the sleeve convex inner bearing surface. The sleeve may further include a pair of opposed radially inwardly extending flanges configured to axially retain the rollers within the sleeve.

Abstract: A finger follower for use in an engine. The finger follower includes a main body including spaced apart first and second walls. The first wall defines a first aperture therein and the second wall defines a second aperture therein, the first and second apertures each having a diameter. The finger follower also includes a shaft assembly that has a first portion positionable between the walls and has a second diameter that is larger than the aperture diameters. The shaft assembly includes secondary portions that extend from the first portion and are configured to be received in the first and second apertures. The finger follower further includes a cam follower positioned between the walls and rotatable about the shaft assembly first portion.
