PURPOSE: To improve friction conditions and to reduce manufacturing costs by designing a securing device between roller support and a roller to be formed of only a securing ring, mounting the ring in a first groove in the inner surface of the roller on the one hand and in a second ring groove in the outer surface of the roller support on the other hand, and opposing the grooves together in the radial direction. CONSTITUTION: One axial mutual securing device between each one roller support 4 and one roller 5 is formed of only a characteristic securing ring 9 which can be loaded in both directions with respect to a roller axis B. The securing ring 8 is mounted in a first groove 15 in the inner surface 11 of the roller 5 on the one hand and in a second ring groove in the outer surface of the roller support 4 on the other hand, and the grooves radially face each other. Therefore, securing members are combined into the one securing ring loaded axially on both sides, whereby the roller support and the roller can be manufactured very easily.
