Bottom roller is used in the gravity of the weighting machine. It is rolled on the crawler chain track or crawler track plate. Therefore, it is used to hold the crawler and prevent the crawler from derailing laterally. Bottom rollers sometimes work in muddy water and are subjected to large shock loads. Therefore, it is required that the seal be reliable, the rim wear resistance and the rolling resistance be small.
