1.Specification:diameter 50-219mm; length 190-1800mm. 2.Dunone UHMWPE Conveyor idler is a patented product,.

 1.Abrasion resistance and long life      The shell is made from UHMWPE which has abrasion resistance 10 times that of HDPE and 7 times that of steel.Dunone UHMWPE roller have been subjected to continuous abrasion in very extreme quarrying, coastal and industrial applications.     2.Impact resistance and Impact energy absorbing        Both the shell and the bearing house are manufactured from UHMWPE, so the roller is capable to absorb considerable impact, and the shock is not transferred to bearing.     3.Effective sealing system      The primary labyrinth seal prevents most of the dust to get into the bearing house, and no water could leak in.     The narrow clearance between bearing house and shaft forms the second sealing, the bearing house are made of UHMWPE which has a very low surface energy and are anti-adhesion, so it is repulsive to dust and water. It is quite difficulty for dust to get through the narrow channel     The third sealing are rubber lip seal on both sides of bearing, they also act as grease retainer     4.Light weight and energy saving      Dunone roller are only one third less in weight than steel roller, they are even lighter than HDPE roller, since they have superior strength .Light weight and low friction result in considerable energy saving.     5.Redused belt damage      UHMWPE shell is self-lubricant, and prevent the adhesion of any transfer material, so no damage was caused to conveyor belt, even in case of roller be stopped.     6.Noise reduction      UHMWPE is a much better noise debase material than HDPE, Dunone roller generate much less noise than conventional steel roller, they are environmentally friendly     7.Corrosion resistance      Dunone roller can withstand humidity, corrosive chemicals, acids, salt and alkalis.     8.No sticking      UHMWPE could not be sticked by any material, so no conveyor material will be sticked to roller surface.     9.Machined face      Machined face of shell yield excellent balance and low T.I.R.10.Low maintenance fee Light weight make it ease to fit and install.The labyrinth cap could be put back easily for clearing dust on line without take off the roller.
