Abstract

A double-row spherical roller bearing, comprising: an outer ring having an radially inner spherical raceway and a radially outer peripheral surface, an inner ring having a radially outer curved-shaped raceway, and roller elements arranged in two axially displaced rows. The outer ring includes an outer peripheral surface first circumferential groove. The first circumferential groove has an axial outer peripheral surface width X fulfilling the following relation: L1≤X≤L2, L2 extends between first end point (intersecting the first normal vector and the outer peripheral surface) and second outer peripheral surface axial end points (intersecting a second normal vector and the outer peripheral surface). The first normal vector is an inverted normal vector of the outer raceway. The second normal vector is an inverted normal vector of the inner raceway. L1 has a length of L2*⅓. End points of L1 are located equidistant to each respective first and second end point of L2.
