Case Study #3

Case Study No.: 50100196
Application: Spiral Freezer Tunnel
Cost Savings: $7,168

The OEM originally supplied 2060 AS (alloy steel) chain with 60 stainless steel split roller links with A2 attachment for this application. The application experienced short life due to the split roller opening up causing the chain to fail; the chain has standard riveting causing the pins to rotate on the side plate caused by tension.

After inspection, Tsubaki designed 2060 HSS (high strength stainless steel) made with a combination of different stainless steel grade with solid rollers. To combat the rotating pin issue, we recommended spun riveting. The changes resulted to 20% higher than standard chain rating and increased the life of the chain by 36%.
