Roller

Detailed Product Description

     We provide UHMW PE Roller  idler based on JIS ,ISO ,CEMA ,DIN standard ,special size are available on reguest.     
     Specification:
     φ89φ102φ108φ127φ133φ156φ159φ168

    1Abrasion 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.
     2Impact 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.
     3Effective 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
     4Light 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. 
     5Redused 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.
     6Noise 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
     7Corrosion resistance
     Dunone roller can withstand humidity, corrosive chemicals, acids, salt and alkalis.
     8No sticking
     UHMWPE could not be sticked by any material, so no conveyor material will be sticked to roller surface.
     9Machined 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.
