Dry Film Lubricant Guarantees High Performance in Hostile Environments while Reducing Wear and Noise

Graphite Block dry film lubricant is composed of synthetic, lubricant-quality graphite that is specifically designed to lubricate trunnion rollers, riding rings and insert seals on rotary kilns, calciners, dryers and other industrial equipment requiring dry film lubrication. 

The Graphite Block lubricant lowers pressure on the bearing thrust mechanism, while reducing forces on bearing end caps or thrust collars. It substantially reduces wear and noise, resulting in decreased maintenance costs; smoother, quieter operation; and longer lasting equipment. 

LE’s Graphite Block is a unique carbon composition manufactured under the tightest internal controls. This makes for a highly consistent graphite block that guarantees optimum lubrication even in the most hostile environments, and prevents remature wear of the graphite.

Benefits and Recommendations

Beneficial Qualities

 N/A
  • Custom - Cut to your specific requirements to maximize benefits and performance. 
  • Wear-Reducing - Greatly reduces friction and wear.
  • Heat Resistant - Designed to perform in hightemperature applications.
  • Self-Extinguishing – Will not sustain combustion under atmospheric conditions.
  • Rain-Resistant – Does not wash off in rain.
  • Noise-Reducing – Stops or substantially reduces high pitch squeal; and ensures smoother,  quieter operation.
  • Clean – Provides clean, dry lubrication.
  • Appearance – Does not glaze over during operation.

Application Notes

 N/A In kiln and dryer applications, the block lubricant transfers from the trunnion roller to kiln tire and lubricates both surfaces during normal rolling. • In overhead and port crane applications, two blocks should be used per wheel. The wheels are double ?
