Rolling bearing comprising two identical rings

A rolling bearing having a longitudinal axis, the rolling bearing comprising:

• a first ring including at least one first rolling ring having at least one first raceway and at least one first sealing ring secured to the first rolling ring, the first sealing ring being formed as a split ring including at least three part rings, the part ring located farthest from the first rolling ring being an end ring, each one of the part rings having one straight through hole oriented along the longitudinal axis and located on a first diameter and at least one shouldered through hole oriented along the longitudinal axis, each one of the part rings located between the first rolling ring and the end ring being an intermediate ring having at least one threaded hole oriented along the longitudinal axis;
• a second ring including at least one second rolling ring having at least one second raceway and at least one second sealing ring secured to the second rolling ring;
• and
• at least one row of rolling elements arranged between the at least one first raceway of the first rolling ring and the at least one second raceway of the second rolling ring such that at least one of the first and second rings is capable of rotating concentrically relative to the other one of the first and second rings about the longitudinal axis;
• wherein two of the intermediate part rings of the first sealing ring are twin rings being identically formed and being adjacent to each other, each twin ring having at least one pair of holes including a shouldered through hole and a threaded hole, the shouldered through hole and the threaded hole being separated by a first angle, each twin ring further having two straight through holes oriented parallel to the longitudinal axis, the two straight through holes being located on the first diameter and being separated by the first angle;
• and
• wherein a channel is delimited by the straight through holes of the part rings extending from the end ring towards the first rolling ring, one of the twin rings delimiting one straight through hole of the channel and the other twin ring delimiting another straight through hole of the channel.
