The invention relates to a rope wheel assembly (40,80) of an elevator, comprising a frame (F), a plurality of rope wheels (4,8,9) for guiding ropes of the elevator, and plurality of bearings (10-12), wherein the rope wheels (4,8,9) are mounted coaxially on the frame (F) such that they are rotatable relative to the frame (F) as well as relative to each other; and the rope wheel assembly (40,80) comprises a central shaft (S) passing through said rope wheels (4,8,9), which central shaft (S) is non-rotatable relative to the frame (F), and the rope wheel assembly (40,80) comprises a hollow cylinder (c) surrounding the central shaft (S), the hollow cylinder (c) being mounted on the central shaft (S) rotatably relative to the central shaft (S), each said rope wheel (4,8,9) being mounted on the cylinder (c) rotatably relative to the cylinder (c). The rope wheel assembly (40,80) comprises a bearing (11) axially between rope wheels (4,8,9) that are next to each other via which bearing (11) they are supported on each other in axial direction. The invention also relates to a compensator and an elevator arrangement implementing the rope wheel assembly (40,80).
