ROYAL 90 GL-4

APPLICATION
  • Gear lubricants are high performance, multipurpose mineral oil based lubricants designed for the lubrication of many types of industrial gear systems like spur, helical, and straight and spiral bevel types operating under severe and wide ranges of speeds, loads and temperatures.
  • These oils are designed to provide outstanding wear protection and excellent thermal stability.
 

PERFORMANCE BENEFITS
  • High thermal stability system helps maintain cleangear and bearing surfaces.
  • Effective system forms a protective film in areasof metalto-metal contact, minimizing wear rates and maintaining efficient transfer of power.
  • Effective oxidation inhibitors and copper passivatorminimize oil oxidation, limiting viscosity increase and promoting long drain intervals.
