Tsubaki reveals true green credentials with 66% reduction in CO2


Tsubaki's 4th generation BS/DIN Standard power transmission roller chain, GT4 Winner, is living up to the company's Eco-Eco promise of delivering economical and ecological benefits to its customers. A recent Life Cycle Assessment (LCA) showed that thanks to environmentally aware material sourcing and manufacturing, coupled with extended operational life, GT4 Winner chain generates 66% less CO2 than comparable products.

GT4 Winner chain features many technical innovations which are designed to ensure that the chain runs more smoothly and lasts longer in operation with fewer maintenance requirements. Features include its perfectly cylindrical bushes with bespoke 'lube grooves' which hold oil at the point of contact, creating an internal reservoir for lubricant. The result of the detailed design work is that, once installed, GT4 Winner chain can last many times longer than traditional chains; ultimately reducing total ownership costs.

A product that is a little cheaper to purchase may require twice the levels of in-service maintenance and still last half the time. GT4 Winner chain has been proven to last longer than any other chain on the market and requires minimal servicing once installed."

Following recent product tests Tsubaki has shown that it isn't just costs which are reduced when customers specify GT4 Winner chain; specification can significantly reduce their carbon footprint too. A recent LCA which compared GT4 Winner to standard roller chain found that it generates up to 66% less CO2 over its entire life cycle.

Taking a benchmark 120 links of chain the company set an inventory of analysis for CO2 emissions including materials sourcing and extraction, internal processing during manufacture, external processing prior to and after manufacture, plus product transportation and scrap. It then compared the amount of CO2 that would be generated throughout the cycle and multiplied it based on the total number of cycles that would be required for a specified length of operation.

Derek Mack continues: "Very few chains on the market can match the service life of GT4 Winner. This means that where you install our chain once and scrap it once, you have to install and scrap competitor chains many times. While there isn't much difference in the running efficiency of one chain to another in application, the total life efficiency very quickly begins to change once you look at it like this. This assessment proves once and for all that not only does GT4 Winner reduce costs over an entire life cycle, it also reduces CO2 emissions."

The results of the LCA showed that every 120 links of GT4 Winner is accountable for 29Kg CO2 compared to the 88Kg CO2 generated by standard industry chain.
