Open Gear Grease

Product code : (GRCSMA)

  • Specifically designed for use in wind turbine pitch and yaw gears as well as industrial gears
  • Solves common gear-tooth issues such as fretting, pitting, corrosion, and general lack of grease between heavily loaded gear sets
  • Provides exceptional water-washout protection, maintaining an appropriate grease film both in yaw and pitch gears as well as industrial gears
  • Provides outstanding wear protection and grease adhesion
  • Exceptional resistance to water washout

Open Gear Grease



AMSOIL Industrial Open Gear Grease is designed specifically for use in wind turbine pitch and yaw gears as well as industrial gears. Its unique combination of base oils, calcium-sulphonate-complex thickeners and special additives solve common gear-tooth issues such as fretting, pitting, corrosion, and lack of grease between heavily loaded gear sets.

PROTECTION FROM THE ELEMENTS

  • Exceptional water wash-out protection maintains appropriate grease film even in extremely humid or salt-ridden environments.
  • Superior load and wear protection when equipment is operating in harsh climates where temperatures are well below freezing.

DELIVERS SUPERIOR GEAR PROTECTION

  • Despite heavy impacts and loads, open gear grease stays in place providing protection competitors are not able to match.
  • Protects against fretting from extreme cyclical loads and vibration while offering protection when the nacelle ratchets during backlash events and places heavy impact-type loads between gear teeth.
  • Creates thin grease filaments that distribute across the gear face after meshing—increasing lubrication during the next pass.
