Feature 7: Solid grease for bearings

Solid grease for bearings

"Solid grease" is a lubricant composed mainly of lubricating grease and ultra-high polymer polyethylene. Solid grease has the same viscosity as grease at ordinary temperature, but by applying a special heat treatment process, this special grease solidifies retaining a large proportion of lubricant within the bearing.

Solid grease for general use

Grease code: LP03

  • More resistant to centrifugal force-induced leakage.
  • Fouling from grease leaks on or around the bearing is positively prevented.
  • Water does not emulsify the grease or cause the grease to leak. Thus, the grease has a longer lubricating life.
  • Unlike ordinary grease, bearings with solid grease exhibits virtually no stirring drag and therefore contributes to lower bearing torque.

Permissible operating temperature range and speed

Temperature at bearing outer ring:
Use the bearing in a temperature range of -20°C to 80°C (60°C max. for continuous operation).
Permissible dn value: 120 000
[dn=bearing bore diameter d(mm) X operating speed n(min-1)]

Solid grease for food machinery

Grease code: LP09

In addition to the advantages of the general-use bearings with solid grease (P-03) as mentioned in a) above, bearings with solid grease type P-09 boasts a high degree of safety because its heat-solidifying grease for food machinery is composed of food-grade lubricating grease that complies with the NSF's H-1 standard (permitting contact with food) and super molecular weight polyethylene approved according to an FDA (US Food and Drug Administration) standard.

Permissible operating temperature range and speed

Temperature at bearing outer ring:
Use the bearing in a temperature range of -10 to 100°C
(80°C max. for continuous operation).
Permissible dn value: 100 000
[dn=bearing bore diameter d(mm) X operating speed n(min-1)]

*Contact with organic solvent, wash oil or other chemicals can degrade the lubricating perfomance of solid grease.
