The invention discloses a guide wheel for a light crawler-type tractor. The guide wheel comprises a hub and a wheel disc. The wheel disc is annular, and the inner side of the wheel disc is integrally connected with the outer side of the hub. A rounded rim is arranged on the peripheral edge of the wheel disc, and the graph, obtained through cutting of a plane passing through the central line of the wheel disc, of the rounded rim is in a circular bead shape gradually narrowing down outwards in the radial direction. The disc faces on the two sides of the wheel disc are provided with a plurality of concave areas concaved towards the middle, and a hollowed hole for communicating space on the two sides of the wheel disc is formed in each concave area. The hub is in a cylindrical shape with openings in the two ends, and the wheel disc is located outside the middle of the hub. The openings in the two ends of the hub are each provided with a first connecting segment and a second segment, sealing pieces are arranged in the first connecting segments, and threads used for being connected with an end cover are arranged in the inner sides of the second connecting segments. The first connecting segments are located on one side close to the middle of the hub, and the second connecting segments are located on one side far away from the middle of the hub. An inward-protruding structure used for separating two bearings arranged in the hub is arranged in the middle in the hub.
