Claim 13:
14. A method for manufacturing an elevator roller for an elevator system, the method comprising the steps of:
forming a shell of a POM material with a running surface;
connecting the shell to a roller body made of a metal material at a common contact surface to form the elevator roller;
wherein the contact surface has a wave profile running in a circumferential direction of the elevator roller; and
wherein the shell has a V-ribbed profile running in the circumferential direction on the running surface, the V-ribbed profile having ribs at a rib spacing corresponding to a wave spacing of the wave profile, 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.
