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.

Uses a Low Friction, Anti-Wear polyacetal combined with an antimicrobial agent for the chain links

Anti-bacterial and mold resistant

Uses an original antimicrobial agent developed jointly with an antimicrobial agent manufacturer.
Effective against the E. coli, S. aureus, lactobacillus, and so on that need to be avoided around food. It also is resistant to mold and has demonstrable results against penicillum.

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.

Applications

• Cleaning in bottling plants
• Direct food conveyance or food conveyance before can sealers
• Conveyors wet from water or dew condensation from processes (especially, exit and entrance of shower equipment, unloading areas on retort equipment, etc.)
• Preventing mold in applications where the environment causes the conveyor to dirty easily
