The invention relates to a roller bearing having an exterior member and an interior member with an interior ring having a raceway and an interior wall which is associated around an exterior bearing surface of a hub of the interior member. The bearing surface has a groove in which an annular member is arranged by having an interior segment axially immobilized in the groove and a exterior segment that projects to form an axial abutment of the ring. On the hub, the interior member has an encoder with a track capable of generating a signal representative of its rotation. The encoder also has a reinforcement for rotatably securing to the member. The reinforcement has at least one projection arranged around the annular member to prevent its radial movement in the groove.

Roller bearing

The invention is a bearing, with an inner member having an inner ring with a raceway and an inner wall assembled around an outer bearing surface of a hub. The outer bearing surface has a groove in which an annular member is arranged having an inner segment axially immobilised in the groove and an outer segment that projects to form an axial stop for the assembly of the inner ring on the hub. The inner member has an encoder. The encoder also has a frame securing it to the inner member. The frame has a stop section between the inner ring and the outer segment.
