Actuator pivot shaft rolling bearing with seal

Abstract

A variable turbine geometry turbocharger with an actuator pivot shaft with a rolling-element bearing having a rolling element between an inner race and outer race. Replacing a standard actuator shaft bushing with a rolling-element bearing may reduce friction and adverse movement in certain applications. Various seals may be feasible, such as a face seal attached to the inner or outer bearing race that could seal against the opposing race.

What is claimed is: 
     
       1. A variable turbine geometry turbocharger including an actuator pivot shaft bearing assembly with a rolling-element bearing with a cylindrical rolling element between an inner race and outer race and a face seal attached to the inner race and that seals against the outer race.
