  • Plastic Top Chain

TPM-SN Series

Uses the same engagement principle as TSUBAKI Silent Chain for ultra-low noise conveyance.

Uses a special sprocket to suppress polygonal movement during engagement for stable conveyance.

    (with float-preventive tabs)
  • TPM-P-SN: Plastic pin type

TPM-SN Series

1. Low noise

Uses the same engagement principle as TSUBAKI Silent Chain (pitch = 19.05mm, 1/2 the pitch of conventional top chain). This greatly reduces conveyor noise compared to conventional chain.

In-house comparison of total conveyor noise

  • 14dB(A) less than TPS826
  • 4dB(A) less than TPM826
  • Using the TP-IR60 on the return roller can further reduce noise by 3dB(A).

2. Structure

Design suppresses chordal action (polygonal movement) during sprocket engagement to the maximum, and its short pitch/multiple hinge construction provides even stabler production.

Only the plastic connecting pin (for connecting two strands of chain) is orange. The plastic base chain pins are white.

Link design ensures that the chain always maintains an upper limit on polygonal movement.

  6. (6) Series code*:
    • [TPM-SN]
      Blank = Standard series, LFW/LFG/LFB = Low friction, Anti-wear, ALF = Ultra-low friction and wear resistant, DIA/DIY = Impact resistant
    • [TPM-P-SN]
      Blank = Standard series, LFW/LFG/LFB = Low friction, Anti-wear, ALF = Ultra-low friction and wear resistant, DIY = Impact resistant

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.
