Roller Chain Wearing Too Quickly Case Study

Roller Chain Wearing Too Quickly – Product Packaging Case Study


A produce packaging company was looking for improved chain wear life on a tomato sizing machine, a common challenge, roller chain wearing too quickly. Due to very damp and acidic working conditions, the roller chain would last no more than a month, much less than the expected 140 days.


An analysis by Diamond Chain found that not only was the acidity of the tomatoes corroding the roller chain, but the load of the machine was too large for the size of chain to handle. Diamond suggested that the company could greatly improve the longevity of its chain by switching from a standard carbon steel roller chain to either a larger sized, corrosion resistant chain or a specially lubricated chain from Diamond’s maintenance free series. Diamond Chain’s Ring Leader O-Ring® maintenance free chain was ultimately selected for this application.


The Ring Leader chain is a better match for this working environment as the o-rings keep out contaminants that can build up and damage the surface area of the chain’s pins and bushings while the sealed in lubrication provides additional protection to the moving parts, reducing wear and elongation and increasing the service life of the chain.


After switching to Diamond Ring Leader O-Ring chain, this produce packaging saw savings of $60,299.74 after one year and $301,498.68 after five years.
