I. Description about Castrol Tribol GR 4747/220-2 HT

• 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.

II. Application of Castrol Tribol GR 4747/220-2 HT

• 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.

III. Advantages of grease Castrol Tribol GR 4747/220-2 HT

• 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 ensure reduced wear, lowered operating temperatures as well as extended service life leading to decreased maintenance and repair costs.
