Abstract
Bearing assembly comprising inner and outer rings and a plurality of rolling elements in the annular space between the rings means having a seat on the inner peripheral surface of one of the rings facing the annular space incuding a throat section having a saw-toot shaped axial profile, a seal system at least at one axial end of the annular space and having at least one general rigid shield member, a cover member of resilient material covering at least a portion of the shield member, the shield member having a separate sleeve-shaped portion and with interposition of at least part of the elastomeric covering, in the annular seat with the sleeve portion of the armature being placed coaxially with the rings and presenting a separate rim, facing towards the outside of the annular cavity, folded over so as to engage in the sawtooth-shaped throat to immobilize the shield axially in the annular seat.
