At the Diamond Chain Company, we manufacture the world's highest-performing roller chain. From the Wright Brothers, to Henry Ford, to global leaders of our time, Diamond Chain is the roller chain most trusted to perform, when performance matters most.
Case Study: Concrete Manufacturing


A leading concrete products manufacturer produces concrete blocks at a rate of approximately 1,667 blocks per hour. Because profitability turns not only on quality, but also on continuity of operations, the company relies on dependable equipment. 


The environment in the manufacturing space contains a high concentration of dirt and concrete grit, because of this, the chain company was using on their tile slacker and pallet delivery machines were elongating and wearing too quickly. This led the company to search for "a quality chain that is dependable and has excellent wear life." 


The Plant Manager for this Concrete Products Division evaluated several chain choices ranging from inexpensive economy chain to high performance Diamond series roller chain, which has an industry reputation for delivering best-in-class dependability and wear life.


To determine which product offered the best overall value, the manager first began by quantifying the costs associated with each instance of a chain replacement:


  • The company produces approximately 1,667 blocks per hour. At a retail value of $1.79 per block, the downtime costs from production equal $2,985 per hour.
  • Labor costs to replace the chain equals twelve man hours at $120/hour for a total expense of $1,440.
  • Total potential downtime expense for each instance of chain replacement was then $4,425.

Given the high costs associated with downtime for chain replacement, it was determined that purchasing the best quality chain would prove the best value to the company in the long run.


Looking at potential product options, the company compared Diamond Chain's Diamond series ANSI 80 and 100 riveted roller chains versus the less expensive mid tier brand that they were using. From Diamond Chain's ROI calculator, the Diamond series showed that they could expect a minimum increase of 50% in wear life over their current roller chain.


The results from switching to Diamond series roller chain has been an increase in the machinery up time of over the projected 50% significantly decreasing downtime and labor costs. The company saved over $6,500 the first year after the switch and is estimated to save up to $33,000 over five years.


Q- How does Diamond Chain mark the links on their products?


A- Diamond Chain uses three distinct product marks to differentiate between its Diamond, Infinity, and Sapphire product series. Diamond Chain's flagship Diamond series includes a stamp of the words "Diamond Chain" along with the Diamond graphic element. The Infinity series includes only the Diamond graphic element stamp while Sapphire has a RSC stamp for Sapphire roller chain.
