Abstract
A mechanical roller bearing comprising two bearing races each having a rolling track, rolling elements arranged between the races, the rolling elements being able to roll against a portion of the rolling tracks, the rolling elements being made of a defined material, wherein it includes a plurality of intermediate blocks arranged between the races, the intermediate blocks being made of a material having a greater stiffness than the stiffness of the material of the rolling elements in directions normal to the rolling tracks, and, when the bearing is subjected to loading below a threshold load, the intermediate blocks have a smaller dimension than the rolling elements in directions normal to the rolling tracks, the races having a greater stiffness than the rolling elements.
