A speed limiter for an elevator system includes: at least one speed limiter wheel having a first radial cam with lobes, and at least a second, phase-shifted radial cam with lobes; a first mass, which is rotatably arranged in a first pivot bearing and which together with a first roller rolls on the first radial cam such that the first mass follows a first oscillating motion when the speed limiter wheel rotates; and a second mass, which is rotatably arranged in a second pivot bearing and which together with a second roller rolls on the second radial cam such that the second mass follows a second oscillating motion when the speed limiter wheel rotates.
