Castrol Tribol GR 4747/220-2 HT High-Temperature Grease


CASTROL TRIBOL GR 4747/220-2 HT (previously named Tribol 4747/220-2) high-temperature grease with TGOA is a clear multi-service lubricant designed to extend the service life of bearings in heavy-duty applications and at elevated temperatures. The high base oil viscosity of CASTROL TRIBOL GR 4747/220-2 HT provides a heavier oil film for applications at slower speeds, higher loads and/or higher temperatures. The patented TGOA additive technology provides for unsurpassed protection against friction and wear in the conditions above.

  • Formulated from a mixture of high-quality synthetic base oils (PAO & ester) and a lithium complex thickener.
  • It contains corrosion inhibitors and antioxidants for long service life.
  • The load-carrying, antiwear and friction-reducing capabilities of CASTROL TRIBOL GR 4747/220-2 HT exceed conventional complex greases. The high performance is the result of the TGOA additives which under relatively high specific loads and related temperatures, promote a non-destructive smoothing of the surface roughness in the micro-range.
  • The smoothing effect leads to increases in actual load-carrying areas and reduces friction.
  • TGOA additives are very effective in protecting the machined surface of bearings during the critical “running-in” period.
  • TGOA additive package automatically reactivates to optimise lubrication and smooth rough surfaces when roughness peaks redevelop in shock load or stop-and-go operations. This is essential as good bearing surfaces mean bearing longevity.
  • CASTROL TRIBOL GR 4747/220-2 HT grease with TGOA is designed as a multi-service lubricant for heavy duty applications of rolling and sliding bearings for temperatures up to 160°C (peak temperatures up to 180°C).
  • CASTROL TRIBOL GR 4747/220-2 HT grease should be used when loads are moderate to heavy and speeds are slow to moderate.

Castrol Tribol GR 4747/220-2 HT High-Temperature Grease Product Advantages:

  • CASTROL TRIBOL GR 4747/220-2 HT with TGOA offers increased load-carrying capability due to higher viscosity base oils and surface smoothing as well as friction-reducing properties of TGOA.
  • The lithium complex thickener is characterized by its excellent working and shear stability.
  • Excellent thermal stability (dropping point >250 °C).
  • The TGOA additives reduce wear at lowered operating temperatures as well as extended service life leading to decreased maintenance and repair costs.

  • CASTROL TRIBOL GR 4747/220-2 HT grease with TGOA should not be mixed with greases using a different thickener.
  • Lubricating intervals should be increased gradually after changing over to CASTROL TRIBOL GR 4747 to ensure complete removal of the previous lubricants and to use the TGOA additives to their full advantage. Their performance might be affected by residual greases containing solid lubricants!
  • At peak temperatures of 180 °C relubrication intervals should be established by inspection.


All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and damage to drum markings. Products should not be stored above 60°C, or exposed to hot sun or freezing conditions.
