Case Study #1

Case Study No.: 30300036
Application: Looper Exit
Cost Savings: $126,189

RS120 competitor’s chain was supplied in strands of four at 137 feet each. The primary issue of this metal processing application was elongation due to lack of lubrication throwing the looper cart out of alignment.

Tsubaki’s technical support team further investigated the issue – the application required a chain that lubricates itself whilst being able to handle static hanging load simultaneously. We recommended having the first 2 feet and the last 2 feet of each strand to be Lambda self-lubricating chain – this was recommended as these were the areas of the chain that were engaged with the sprocket; for the middle area we recommended RS120 Heavy – to withstand the static hanging load. These four strands were matched and tagged to assure that the chain travels and wears evenly. This “hybrid” chain not only resolved the lubrication issue as well as uneven stretching but also improved the chain life ultimately.

The customer paid three folds than what they paid for the competitor’s chain, however, Tsubaki’s innovation with the “hybrid” chain increased the life by almost six folds and saved this customer a total of $126,189.
