Chain Wear Reduction

Situation:

A major roller chain manufacturer wanted to reduce chain wear and extend the re-lubrication interval.

Testing:

A set of control chains were lubricated with heavy-duty wet lubricant, and a second set were prepared with DICRONITE® dry lubrication and the heavy-duty wet lubricant. The chains were then run at:

  • ambient temperature,
  • 798 feet per minute,
  • and under an applied load of 533 pounds per strand of chain.

Chain elongation measurements were taken at 50 pounds per square inch gauge pressure.

Results:

Testing was stopped at 132 hours (versus a planned 150 hours) due to one of the control chains breaking for a second time. Two parameters were measured at the 132-hour mark: the number of dry joints and chain elongation.

On average, the chains with DICRONITE® had 42% fewer dry joints versus the control group of only heavy-duty wet lubricant. The DICRONITE® chains also displayed an average of 42% less elongation, 51% less elongation when comparing best performing from each type, and 90% less chain wear in the best case.

This translated into longer chain life, increased gear life and lower operating temperatures. Adding DICRONITE® dry lubrication resulted in less down time and extended maintenance intervals, which reduced overall costs for their customers and enabled the manufacturer to charge a premium.
