The invention relates to a rolling device (6, 7) for a displaceable cross frog (1), comprising a sliding strip (18), at least one roller (11), and at least one roller bearing (12) which is fixed to a fixed part of the points. The at least one roller (11) is mounted on an arm (9) of a two-armed lever (10). The pivoting bearing (12) of said lever (10) is arranged in a carrier (13) which is connected to a fixed part of the points. The arm (18) of the two-armed lever (10) which opposes the roller(s) (11) can be pivoted against a spring (19) with adjustable elastic force.
