Anco bearings are made from advanced materials via special technology with independent intellectual rights.Anco materials is a complex high performance polymer composites produced by employing thermoseting polymers with multiple hydrogen-bonding structure as matrix materials,and self-lubricating micro/nano-particles with different morphologies as fillers.The mechanism of asymmetric hydrophilic is used to establish the balanced and synergically improved properties including water lubrication,dry friction,dimension stability as well as mechanical strength.The materials were developed by changchun Institute of Applied chemsitry chinese Academy of sciences,and authorized exclusively  to changchun A&Z Science Co.,Ltd.For product development.The whole process and every detail for Anco bearings production is visible by hte administration and traceable in the documents.The key producing processes are required to take the cross-validation to ensure that each manufactured product meets the requirements for high-standard quality control.Every Anco bearing has a unique code ofr identification so as its quality control is traceable,embodying the concept of "Innovation from A,Quatily to Z" for A&Z company. A&Z company can supply four different types Anco bearings,including NZ-PN,NZ-PX,NZ-PXL,and NZ-RN.Owning to the features of self-lubrication,high loading capacity,anti-fouling,ease of processing and no pollution to the environment,as well as superior properties in comparison to their international competitors,Anco bearings have been widely used in the fields such as ship,water pumps and so on.
