  • Plastic Top Chain

TPU Series

Sideflexing conveyance chain with float-preventive tabs.

Minimum sideflex radius: 500mm

Version of TPS Series for sideflexing conveyance.

  • TPU = Stainless steel pin type
  • TPU-P = Plastic pin type

  • Float-preventive tabs prevent floating on corner and incline/decline sections, and prevent scratches to plate surfaces on the return way.
  • Can use the same sprocket as the TPS and TPU Series. Parts can be interchanged.
  • Plastic pin types are entirely lightweight plastic for easy handling and replacement. Users can expect longer chain life under water lubricated conditions than with stainless steel pins.
  • The shape of the float-preventive tabs on stainless steel type chains (plate width: 82.6mm) was changed in October 2008. *Plastic pin types were not affected.
  • Old and new style chains can be connected.

  2. (2) Plate width: mm (Example) 826 = 82.6mm
  3. (3) Plastic pin code: Blank = Stainless steel pin type, P = Plastic pin type
  4. (4) T = With float-preventive tabs
  5. (5) Series code*:
    • [TPU]
      Blank = Standard, LFW/LFG/LFB = Low friction, anti-wear, ALF = Ultra-low friction and wear resistant, WR = Low wear, DIA/DIY = Impact resistant, KV = Heat resistant
    • [TPU-P]
      Blank = Standard, LFW/LFG/LFB = Low friction, anti-wear, ALF = Ultra-low friction and wear resistant, WR = Low wear

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.
