Patent ID: 8109458

Claim:
A rolling bearing for a rocker arm, said rolling bearing comprising: an outer part; an inner part; and a plurality of rolling elements positioned between the outer part and the inner part, each of the rolling elements comprising: a first side, the first side defining a contact face for the outer part, a second side opposite the first side, the second side defining a contact face for the inner part; a third side, and a fourth side opposite the third side, the first side defining a curved face having arc lengths on opposite sides of the curved face, the arc lengths being arc lengths of a same imaginary circle when viewed in cross section, the arc lengths of the first side each having a first terminal end adjacent the third side and a second terminal end adjacent the fourth side, the second side defining a curved face having arc lengths on opposite sides of the curved face of the second side, the arc lengths of the second side being arc lengths of a same imaginary circle when viewed cross sectionally; the arc lengths of the second side each having a first terminal end adjacent the third side and a second terminal end adjacent the fourth side, the third side extending from between the first terminal ends of the arc lengths of the first side to between the first terminal ends of the arc lengths of the second side to define a planar cord portion of the rolling element; the fourth side extending between the second terminal ends of the arc lengths of the first side to between the second terminal ends of the arc lengths of the second side to define a planar cord portion of the rolling element; and the cord portions defined by the third and fourth sides extending between the first and second sides define a width of the rolling element such that the width of the rolling element adjacent the first side is greater than the width of the rolling element adjacent the second side.
