R210 track roller excavator bottom carrier roller and top roller Fit For Hyundai\

  The type of roller used for a combined track is different from that of a monolithic or rubber track: the rollers of a combined track roll on the guide rails, while the rollers of a monolithic or rubber track roll on the track shoes. There are two types of rollers for combined tracks, one with a single flange and the other with a double flange. The former is easy to manufacture; Therefore, the application is more common, and the latter is rarely used. The purpose of having a flange is to prevent the track from moving laterally relative to it to prevent derailment when turning. Usually the height of the flange h=10~20 mm. In order to reduce the friction between the side of the wheel flange and the side of the guide rail, the side of the wheel flange is often made into an inclined plane, and the angle of the bevel α=20°~30°.Monolithic or rubber tracks, because they have raised teeth cast on the inner surface of the track shoes to prevent lateral movement of the track to the rollers, have a straight roller rim and do not require a flange. But each roller must be a double-row rim. The number of rollers can make the grounding pressure of the track more uniform, so that walking on the wet and soft soil can reduce the subsidence, but on the other hand, because the length of the track is certain, the number of rollers is more, the diameter of each of them must be small, which increases the rolling resistance, generally speaking, as the crawler walking mechanism of the combine harvester, the number of rollers is often 3~4, and a few use 6.
