  • Plastic Modular Chain

BT5 Series

Chain pitch: 15mm

The belt-like wide conveying surface and chain construction enable accurate drive.
A revolutionary chain that goes beyond the traditional concept of belts and chains to provide the functions of both.

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.

1. Features

Wide conveyance width
Provides a wide conveyance surface with its combination of interlocking engineering plastic modular links.
Smooth transference
Short pitches mean a smaller sprocket and smooth transference between conveyors.
Easy maintenance
Composed of three parts -- modular links, pins, and snap attachments, for easy assembly and disassembly. Modular links that break can be replaced in sections, reducing maintenance time.
Accurate conveyance
The chain and sprocket engagement creates none of the slippage or damage to chain ends that is found on flat belts for accurate conveyance.
Prevents meandering
Types with tab guide attachment will not meander even at high speeds, providing safe conveyance even during lateral transfer between conveyors.
Energy savings
Lightweight thanks to its engineering plastic, which makes handling easy and enables conveyors that require less power.
Uses engineering plastic approved by the Food Sanitation Act, enabling conveyors that match food standards.
