NP Industrial Gear Oil TK


NP Industrial Gear Oil TKis a premium quality, lead-free, extreme pressure (EP) gear oil utilizing sulphur-phosphorus EP technology. It has the additional advantage of a tackifier which allows for resistance to flinging and the formation of a tenacious film which resists run off. It is also extremely cohesive and adhesive. NP Industrial Gear Oil TK is manufactured from premium quality hydro-treated base oils, which contain lower levels of impurities, and are blended with an advanced additive package. Without these impurities, that limits the performance of conventional base oils, the use of NP Industrial Gear Oil TK results in:

  • Anti-wear performance
  • Corrosion protection
  • Oxidation stability
  • Thermal stability
  • Anti-foam properties


The use of NP Industrial Gear Oils TK would result in:

  • Minimizing wear of heavy and shock loaded enclosed gears.
  • High load carrying capacity in steel gear transmissions.
  • Good anti-friction characteristics in steel/phosphor-bronze gear units.
  • Less downtime and longer gear-set working life.
  • Good oxidative and thermal stability in systems with bulk oil temperatures up to 100oC.
  • Minimizing of harmful sludge and emulsions.


Main Applications

  • Recommended where the use of EP lubricants are specified or required.
  • Enclosed industrial gear drives, including worm gears.
  • Steel/Phosphor-bronze gear sets
  • High load carrying capacity in steel gear transmissions except for automotive hypoid gears.
