Abstract
A bearing is provided which includes a first set of rolling elements, a second set of rolling elements spaced away from the first set of rollers, a race at least partially enclosing the first and second sets of rolling elements, and a pre-loading element in the race between two outer sections of the race applying pre-load forces to the first and second set of rolling elements. In this way, a simplified bearing structure is achieved while better maintaining pre-load forces.

2 more elements
A method for operating a turbocharger comprising:
- applying a pre-load force to a first and second set of rolling elements in a turbocharger bearing via a pre-loading element integrated into a bearing race in the turbocharger bearing;
- and
- rotating a turbocharger drive shaft coupled to the turbocharger bearing during application of the pre-load force.
A bearing system comprising:
- a double row bearing including a first set of rolling elements connected to a second set of rolling elements by a spring coil integrated into a bearing race and exerting a pre-load force on the first set of rolling elements and the second set of rolling elements.
