Castrol Tribol GR 4747/220-2 HT

Castrol Tribol GR 4747/220-2 HT

Product description

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. Because of the high base oil viscosity 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 under those adverse conditions provides for an unsurpassed protection against friction and wear.

- CASTROL TRIBOL GR 4747/220-2 HT is formulated from a mixture of high-quality synthetic base oils (PAO & ester) and a lithium complex thickener.

- In addition to this 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. 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 an increase of the actual load carrying area and reduces friction.

- TGOA additives are very effective in protecting the machined surface of bearings during the critical “running-in” period.

- Good bearing surfaces are essential for long bearing life. If, because of shock loads or stop-and-go operation, surface roughness peaks redevelop, the TGOA® additive package is automatically reactivated. Surface roughness is again smoothed and lubrication optimized.


- 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.

- Good thermal stability (dropping point >250 °C).

- The TGOA additives ensure reduced wear, 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 is designed as a multi-service lubricant for heavy-duty applications of rolling and sliding bearings for temperatures up to 150°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 speedsare slow to moderate.
