Product description

Cement industry, Food industry, Mining, Paper industry
Examples of application

  • Heavily loaded spur, bevel and worm gears in rolling mills, crushers, mills, calenders, cranes, conveyor systems and heavy machinery used in open pit mining
  • Oil lubricated roller bearings of vertical roller mills and roller presses
  • Gear boxes and bearings exposed to continuous operating temperatures above 100 °C
  • Gear units with higher oil sump temperatures or requirements regarding extended oil change intervals

  • Excellent wear protection
  • Very high ageing resistance
  • High load carrying capacity
  • Excellent oxidation and shear resistance
  • Extended oil changing intervals
  • Reduces friction losses in the gear during operation and can thus reduce the oil sump temperature in the gearbox
  • Very high viscosity index
