TSUBAKI 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.

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

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).

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.

Reference Number System

(1) Model
(2) Plate width: mm (Example) 826 = 82.6mm
(3) Plastic pin code: Blank = Stainless steel pin type, P = Plastic pin type
(4) Type
(5) T = With float prevention attachments
(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.
