Case Study #2

Case Study No.: 50100197
Application: Synthetic Gypsum Bucket Elevator
Cost Savings: $7,787 and counting

The customer was using a competitor’s 4850 chain with G6 attachment on every pitch to move raw synthetic gypsum via buckets to the next process area. Gypsum would get into the pin and bushing area and cause the pin to wear, causing competitor’s chain to last for 2 years.

Although the chain lasted 2 years, Tsubaki came up with an improved solution to further prolong chain life. We recommended hardened stainless steel pins and bushings as well as extended bushings through the inner sidebars and installed nitride seals (SJ2) on the ends of the extended bushings to help reduce corrosion and wear within critical areas. The SJ2 technology prevents the gypsum from getting into pin-bushing are, thus, increasing wear life.

The cost of the new chain is more than twice as much as competitor’s. However, the chain has been running for 4.5 years (more than two folds of the previous chain life) and Tsubaki’s chain shows no wear, no elongation with all the seals intact.
