DICRONITE Coating For Chain Wear

Service Details:

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 downtime and extended maintenance intervals, which reduced overall costs for their customers and enabled the manufacturer to charge a premium.

Companies including nasa, general dynamics and Lockheed rely on Dicronite® dry lubrication for:

• Vacuum pump bearing lubrication
• Linear and rotational motion devices in satellites and space vehicles
• Rivets and connectors in space vehicles
• Actuators and valves
• Lubricating and reducing fretting of titanium, stainless steel and aluminum
• Components in electron microscope.
