ABSTRACT:
A roller bearing consists of a hollow cylindrical main body, two annular locating plates, a plurality of rolling bodies and elastic elements. The cylindrical main body is provided with at least three roller grooves equidistantly and equiangularly spaced and disposed around its interior hollow. Each roller groove is configured to have an elastic element seat arranged at its deeper end. The groove wall around the groove opening connected to the interior hollow of the main body extends and forms a reduced neck portion, which makes the groove opening have a width smaller than the diameter of rolling bodies to keep rolling bodies from dropping out of the groove. On the central area of each end surface of the cylindrical main body is an inner annular portion and between end surfaces of the main body and of the inner annular portions are provided with locating grooves.
