When a tissue manufacturer was struggling with the performance and reliability of the chain drive feeding tissue logs into an accumulator it turned to Tsubaki for help in reducing the lost production time. Using its RetroFit service to fit a high performance, lubrication-free Lambda chain on the machine, Tsubaki provided a solution that increased availability, improved product quality, reduced maintenance costs and increased productivity.

As one of the world's premier manufacturers of power transmission products, Tsubakimoto has developed a wide range of reliable products, specifically designed to meet the tough working environment of the paper and pulp industry.

From beginning to end, the paper manufacturing process involves the continuous movement of materials from the original woodchip to the finished paper roll and each process can benefit from the expertise of Tsubaki's design engineers. From drive chain and sprockets to couplings and reduction gearboxes, Tsubaki can deliver a wide range of products that will reduce the total cost of ownership (TCO) and improve productivity and profitability.


The efficiency and reliability of a chain driven system highly depends on the interaction between the chain and sprocket. Just the smallest discrepancy in size can lead to stress damage to the chain, while low quality materials can cause the sprocket to wear and require early replacement. The Tsubaki range of sprockets has been manufactured from high quality steels to integrate seamlessly with all standard chain sizes and ensure a long and reliable service life.


All of the carbon steel sprockets supplied by Tsubaki as standard from stock feature induction hardened teeth to ensure that the wear life of both the sprocket and chain is maximised.

With so many companies claiming expertise in manufacturing roller chain products that do not require any external lubricant throughout their lives, Tsubaki, the original creators of  lube-free chain explain how it is done and detail some surprising real world benefits...

There are a number of ways of achieving non-lube performance of drive chains. These vary with the load capacity and life requirements of the transmission medium. Today engineering plastics, especially self-lubricating acetyl types, play a part but, in the main, these type of chains suit applications where corrosion resistance and weight saving are more important than load capacity. Where conventional externally lubricated steel roller chain is normally used power transmission capacity and wear life are the main criteria for selection and an all steel lube-free chain is required.
