1. An elevator roller for an elevator system, the elevator roller comprising:
a roller body made of a metal material;
a shell made of a POM material and forming a running surface ending in a circumferential direction about an outer surface of the elevator roller;
wherein the shell and the roller body each have a wave profile running in the circumferential direction on a shared contact surface; and
wherein the shell has, on the running surface, a V-ribbed profile aligned with the wave profile of the roller body, the V-ribbed profile having a rib spacing that corresponds to a wave spacing of the wave profile of the roller body, where a groove between each rib of the V-ribbed profile of the shell aligns radially with a valley of the wave profile of the roller body, where the groove and the valley each correspond with a location of locally minimum radius from an axis of rotation of the elevator roller.
