Abstract
The invention concerns a roller bearing including an outer ring, an inner ring, at least a row of rolling elements arranged between two raceways of the outer and inner rings, a seal between the outer and inner rings, and a data sensor assembly comprising a non-rotatable sensor unit borne by one of the rings and a rotatable encoding element borne by the other ring. An seal is provided on the side of the data sensor assembly to isolate the assembly from the inside of the roller bearing by co-operation with the rotating ring in a zone axially located between the encoder active part and the rolling elements.
Claims20
A rolling bearing device comprising an outer race, an inner race, at least one row of rolling elements arranged between two raceways of the outer and inner races, a first sealing means between the outer and inner races, an information sensor assembly comprising a sensor unit supported by the non-rotating race of the bearing and an encoder element comprising an annular support and an active part, said encoder element being mounted on the rotating race via the annular support, and at least one second sealing means provided on the information sensor assembly side to isolate said assembly from the inside of the bearing by collaborating with the rotating race in a zone lying axially between the active part of the encoder and the rolling elements, wherein the annular support of the encoder element comprises an armature comprising a radial portion coming into contact with an external radial face of the rotating race, the active part of the encoder element being arranged axially on the outside of the rotating race.
