A ball bearing that provides an inner race, an outer race, at least one row of balls and at least one cage for spacing apart the row of balls and having a wire extending inside a rolling space delimited by the outer race and the inner race. The bearing also provides at least one seal that includes coupling means for fastening to the wire of the cage.

Ball bearing comprising a cage provided with a wire and a seal

The bearing provides an inner race, an outer race, at least one row of rolling elements, and at least one cage for spacing apart the row of rolling elements. The bearing further provides at least one seal that includes means for hooking which are configured to permit the retention of the seal on the cage in at least two predetermined axial hooking positions relative to the outer and inner races.

A cage for a ball bearing is provided with a wire having a first group of heels spaced apart in the circumferential direction and form a first discontinuous ring, a second group of heels spaced apart in the circumferential direction and form a second discontinuous ring, and a plurality of connecting portions extending between one of the heels of the first group and second group. The connecting portions and the heels of the first group and/or the second group delimit a plurality of spaces each intended to receive a ball of the bearing. The cage also provides at least one interposed part disposed inside each space and is provided with a body for accommodating a ball and coupling means for fastening the body to at least one of the connecting portions of the wire. Each of the bodies of the interposed parts fully positioned in the circumferential direction.

A rolling bearing with rolling bodies includes an outer ring, an inner ring and rolling bodies arranged in a rolling chamber. The rolling bearing includes at least one flange mounted on a first ring and extending to a second ring and fastened onto the first ring and a first annular band at right angles to an axis of rotation of the rings and offset, along the axis, relative to the fastened portion. The flange provides a second annular band and a third annular band arranged respectively radially inside and radially outside the first band and offset axially in the direction of the rolling bodies, using a first setback and a second setback. An edge of the flange, opposite to the portion fastened onto the first ring, is folded back towards the rolling chamber and extends in a direction parallel to a radial surface of the second ring.
