FIELD: railway transport.
SUBSTANCE: invention relates to the field of the upper structure of a railway track, in particular to devices for the movement of a switch blade. The device contains a base and a sliding unit. Longitudinal channels are formed inside the body of the sliding unit. The channels are filled with balls. The diameter of the balls is higher than the height of the body. The lower part of the body on the side of the frame rail has the form of the upper part of the point rail plinth with an emphasis at the end limiting the movement of the blade. There are a number of balls in working condition under the plinth of the blade. A lid with holes is installed above the balls.
