  • Plastic Top Chain

TPUSR Series

Allows for freedom of layout thanks to its small sideflex radius. Perfect for conveying in tight spaces.

Minimum sideflex radius: 150mm

  • TPUSR550: Stainless steel pin type/Plastic pin type
    Plate width: 55.0mm (With float-preventive tabs)
  • TPUSR826: Stainless steel pin type/Plastic pin type
    Plate width: 82.6mm (With float-preventive tabs)

  • Small sideflex radius (150mm) allows for freedom of layout.
  • Uses a comb-shaped plate for stable conveyance. Ideal for conveying PET bottles, dessert cups, paper packs, and other unstable containers.
  • Uses a corner disc in curved sections that rotates in the corner sections from rolling contact, thereby minimizing the generation of wear dust and creaking noises.
  • Float-preventive tabs prevent floating on corner and incline/decline sections, and prevent scratches to plate surfaces on the return side.

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.
