Abstract: A roller for an elevator system has a roller body made of a metal material and a shell made of a POM material forming a running surface of the elevator roller. The shell and the roller body each have a wave profile running in a circumferential direction on a shared contact surface, wherein the shell has, on the running surface, a V-ribbed profile aligned with the wave profile of the roller body that has a rib spacing which substantially corresponds to a wave spacing of the wave profile. The elevator roller is manufactured using a molding process.
