According to China national standards, diameter of rollers are ?76.3??89??108??133??159??193.7??219 etc, subject to belt width and speed. lengths of rollers are standard series, selected by belt width and types of idlers for bearing, consideration is taken into capacity and life of bearing with every single roller. Usually, idler consists of shell, shaft, bearing, housing, seals and snap ring . Idler must be of unique structure, reasonable fitting and accurate assembly, resulting in high capacity and long service life.
