Lubricant application story: Sliding runners
Customer’s area of concern
  • Customer’s description of component: Kiln flexible sealing
  • Previous solution/product previously used: Lithium-based grease with EP additives
  • Market segment: Cement
  • Component/application: Sliding runners
  • Major market: Maintenance, repair & overhaul (MRO)
  • Product: MOLYKOTE® BR-2 Plus Multi-Purpose Grease
Operational parameters (LETS)
  • Load: High, with shock loading
  • Environment: Outdoors; dusty
  • Temperature: -40 to +130ºC
  • Speed: Up to 1.5 m/s
  • Process description: Centralized lubrication system (lubrication onto the sliding surface)


Customer’s critical requirements
  • Problem category: Wear/failure
  • Problem details: The grease was quickly oxidizing from constantly being heated to +130ºC and being exposed to coke dust. There was wear on the contacting plate. As a result, the kiln seal was failing, resulting in coke being emitted into the atmosphere.
  • Root-cause analysis: The previously used grease (with EP additives) didn’t withstand the higher temperatures or abrasive dust particles.


MOLYKOTE® Smart Lubrication™ solution selected
Our product/differentiators

Our product provided good adhesion, wear and corrosion protection, and long-term stability, and it contains solid lubricants. It provides resistance to degradation from constant heating and is suitable for long-term lubrication. Solid lubricants form a thin film on contacting surfaces, reducing their wear.

Result: Our solution

When using grease with solid lubricants, the seal replacement service life was extended from six to 24 months, reducing maintenance, downtime and equipment costs.
