Technology
Superior Material:
Roller pipe are made of ultra high molecular weight polyethylene(UHMW-PE), an engineering plastic with a molecular weight of approximately 3 to 3,5 million g/mol, noise damping, highly wear resistance, self-lubricating.
Plus, with precise machining, it can significantly lower the TIR rate to 0.1mm or even less, dynamically balance to ISO1940-G16, lower the noise produced by vibration.
Patented Water & Dust Proof Sealing System:
1. Mutipal labyrinth + lip sealing system will prevent any contaminants such as dust, sludge, water etc, perfect for brutal working environment.
2. Using deep groove ball bearing.
