  • There are other models available that do not use the description "Standard Series", such as roller tables and universal chains.
  • The appearance of the Standard Series will vary by chain. Please refer to each individual product page in the catalog.

Low Friction, Anti-Wear Series (LF Series)

Uses Low Friction, Anti-Wear polyacetal for the chain links.

Protects conveyed items
15 - 45% lower coefficient of friction than the Standard Series, less line pressure during accumulation
Long life
Less chain load means 1.2x - 2x or more the life of the Standard Series
Less required power
Smooth branching and accumulation of conveyed items

Chain links available in three colors, all with the same performance.

Applications

  • Versatile option that can be used in a wide variety of applications.
  • For when chain wears and elongates more quickly in harsh usage conditions (high speed, high load), and its replacement cycle is therefore shorter compared to Standard Series
  • For when line pressure is high and scratches to product must especially be avoided

ALF Series Ultra-low Friction And Wear Resistant Chain

A new material developed by Tsubaki, and a new solution for dry running

  • Tsubaki developed a new original material that combines silicone lubricant for dry running applications.
  • 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 as the conventional ULF Series.

Applications

Tsubaki recommends using ALF Series for the following applications, especially to reduce the use of lubrication in beverage production lines.

  • Processes where lubricant cannot be used (caser lines)
  • Processes using dry lubricant (inspection lines before caser lines)
  • Conveyors with accumulators and processes where chain speed is high on single line conveyors (single filers, inspection lines, and printing lines)
  • ALF Series chain and PLF plastic rails combine the use of a silicone lubricant, so it cannot be used under printing process conditions or under conditions where silicone will have an adverse effect.
  • When replacing the ALF Series, we recommend replacing rails.
  • When using ALF Series, please use return rollers that can rapidly rotate or return rollers with an outer diameter of φ60 (high inner/outer diameter ratio).

Uses a special material combined with a silicon lubricant, so it cannot be used in areas where ink repelling during the printing process is a concern.

Applications

  • Conveying PET bottles and paper packs
  • On accumulation areas before casers and other packing equipment or inspection equipment.
  • Converging from multi-strand to single strand lines

Durability
Uses an inorganic antimicrobial agent for long-lasting performance.
The antimicrobial agent is folded into the plastic material at the manufacturing stage for uniform distribution over the entire link. This allows the chain to maintain its antibacterial/antimicrobial performance even when the chain surfaces wear.
Safety
Uses a highly safe antimicrobial agent.
The additional antimicrobial and antibacterial functions make it even more suited to food applications.
High Functionality
Links use Low Friction, Anti-Wear material.
There are virtually no changes to performance with the addition of the antimicrobial agent to give you Low Friction, Anti-Wear performance.
