The invention relates to a roller of a support arrangement for a rotary milking platform. The support arrangement comprises a first rail member (4) fixedly connected to the rotary platform (1), a second rail member (5) stationarily arranged in a position below the platform (1), and a plurality of rollers arranged in a vertical space between the first rail member (4) and the second rail member (5). The roller (8) is one of said plurality of rollers, and comprises a peripheral surface (8c) comprising a contact surface (8c1) to be in contact with a contact portion (4d) of the first rail member (4) and a contact portion (5d) of the second rail member (5). The peripheral surface (8c) of the roller (8) comprises two bevelled surfaces (8c2) arranged at opposite sides of the contact surface (8c) which are located at a smaller distance (d) from a rotary axis (8g) of the roller (8) than the contact surface (8c1). |
