Abstract
The rolling bearing provides a first ring and second ring capable of rotating concentrically relative to one another, at least one first wire race mounted in the first ring, at least one second wire race mounted in the second ring, and at least one row of radial rollers radially interposed between raceways provided on the first and second wire races. The second ring comprises at least two guide flanges to axially retain therebetween the row of radial rollers. The first ring includes at least one retaining rib extending into the radial space that exists between the first and second rings and towards the second ring, the retaining rib protruding radially relative to the raceway of the first wire race.
Claims9
A rolling bearing comprising:
- a first ring, and
- a second ring positioned concentrically with the first ring to define a radial space therebetween,
- at least one first wire race mounted in the first ring,
- at least one second wire race mounted in the second ring, and
- at least one row of radial rollers positioned in the radial space between raceways provided on the first and second wire races, the second ring comprising at least two guide flanges to axially retain therebetween the row of radial rollers, the at least two guide flanges each having a first edge abutting the row of radial rollers, wherein
- the first ring comprises at least one retaining rib extending into the radial space that exists between the first and second rings and towards the second ring, the at least one retaining rib protruding radially relative to the raceway of the first wire race, the at least one retaining rib having a second edge capable of abutting the row of radial rollers when centers of the first and second wire races are axially offset, and
- when the first and second wire races are axially aligned the second edge of the at least one retaining rib is not axially aligned with either of the first edges of the at least two guide flanges.

- the axial length of the raceway of the first wire race is bigger than the axial length of the raceway of the second wire race, and wherein
- the retaining rib is positioned so that retaining ring extends from a wall surface that forms the groove of the first ring such that the groove and retaining rib form a continuous surface.
