Ex120 Ex30 PC30 Excavator Track Roller Bottom Roller Lower Roller for Hitachi Komatsu

  There are two types of rollers for combined tracks, as shown in Figure 1 below. One is a single flange and the other is 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°.
