Mining Machine Transition Idler Spare Parts

Transition idlers are mounted at either end of the conveyor, near the head and tail pulleys. And are available in 3 or 5 rolls to suit required belt width. used on the carry side of the conveyor to support the conveyor belt as it goes from trough to flat position. the most parts of idler is bearings, we provide unique high quality deep groove ball bearing, with thicker inner and outer rings.  the reason for this is that the conveyor belt is flat as it passes over the pulleys, under high tension. As the belt changes its form to a full trough of say, 35 degrees (i.e. From tail pulley to full trough angle), the belt must be supported through this transition zone. If the belt was fed directly into a full trough from the tail pulley, the belt edges would be over-stressed and damage would result. Similarly, as the troughed angle changes to zero at the head- end, transition idlers provide support through the transition zone. The number of transition idlers required depends on the trough angle of the conveyor.
