  • Plastic Modular Chain

WT2500 Series

Chain pitch: 25.4mm

We increased the number of hinges and thickened the modular connections to give the chain increased strength.

  • WT2505-K: Closed type
  • WT2506-K: Open type

Notice: Integration of ULF Series with ALF Series

  • We will be integrating ULF Series Plastic Top Chain with ALF Series on orders from April 2017.
  • We will be integrating ALF Series with ULF Series Plastic Modular Chain and Plastic Block Chain on orders from June 2017.
  • Contact a Tsubaki representative for more information regarding ULF Series after integration.
  • ALF Series (ultra-low friction and wear resistant series) dramatically reduces the amount of wear debris generated from sliding with running rails (ultra high molecular weight polyethylene) under non-lubricated conditions while maintaining the same ultra low coefficient of friction coefficient as the conventional ULF Series.
