Abstract
A full complement antifriction bearing includes an inner race, an outer race, and rolling elements organized in a circular row between the races without a cage or retainer for separating the rolling elements. While the absence of a cage or retainers enable the bearing to have the maximum number of rolling elements and thus transfer greater loads, adjacent rolling elements contact each other. Each rolling element or every other rolling element is covered with a tribological coating that retards adhesive wear and reduces friction.
Claims24
A full complement antifriction bearing for accommodating rotation about an axis, said bearing comprising:
- a first inner race having a steel raceway;
- a second race having a steel raceway presented toward the raceway on the inner race;
- and
- steel rolling elements located between the first and second races where they contact the raceways on the races, the rolling elements being arranged such that adjacent rolling elements contact each other, the surfaces of at least every other one of the rolling elements where the rolling elements contact each other and the steel raceways being covered with a tribological coating, the said steel raceways on the said first and second races having no tribological coatings.
