Abstract: A backing ring (R) that serves to back an antifriction bearing (B) on the journal (2) of a rail car axle (A) includes an annular body (36, 52, 66, 88, 98, 118, 136, 160, 170, 188, 214, 234, 254) that seats against a fillet (6) that is located at the end of the journal and also a lip (46, 56, 70, 90, 100, 120, 138, 162, 172, 190, 216, 236, 268) that projects over a larger dust guard diameter (4) that is located on the axle immediately beyond the fillet. In addition, the backing ring includes a stabilizing element (38, 54, 68, 96, 102, 122, 142, 166, 178, 194, 224, 242, 256) which cooperates with the lip and with the dust guard diameter to lessen the tendency of the annular body to work against the fillet and create a fretting wear when the journal undergoes cyclic flexures. The stabilizing element accommodates dust guard diameters of varying size. The stabilizing element may also establish a seal between the lip and the dust guard diameter.

Abstract: A full complement antifriction bearing (A) includes a steel inner race (2), a steel outer race (4), and rolling elements (6) organized in a circular row between the races without a cage or retainer for separating the rolling elements. While the absence of a cage or retainers enable the bearing (A) to have the maximum number of rolling elements (6) and thus transfer greater loads, adjacent rolling elements (6) contact each other. Each rolling element (6) or every other rolling element (6) is covered with a tribological coating (30) that retards adhesive wear and reduces friction.

Abstract translation: 一种完整的抗磨轴承（A）包括钢制内座圈（2），钢外座圈（4）和滚动元件（6），所述滚动元件在所述座圈之间以圆形排列，没有用于分离滚动元件的保持架或保持器。 虽然没有保持架或保持器使得轴承（A）具有最大数量的滚动元件（6）并因此传递更大的载荷，但相邻的滚动元件（6）彼此接触。 每个滚动元件（6）或每隔一个滚动元件（6）都覆盖有摩擦学涂层（30），以减少粘合剂磨损并减少摩擦。
