  • Plastic Top Chain

TPU-USR Series

Has a small minimum sideflex radius to allow for more compact layouts.

  • TPU-USR: Stainless steel pin type
    (With float-preventive tabs)
TPU-USR Series

1. Features

  • Has a smaller minimum sideflex radius than TTUP or TPU Series (190mm), allowing for compact layouts.
  • Can use the same sprocket as TPS and TTUP Series. Parts can be interchanged.
  • Float-preventive tabs prevent floating on corner and incline/decline sections, and prevent scratches to plate surfaces on the return way.
  • Not available with plastic pins.

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.
