CASTROL TRIBOL® 4747 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® 4747 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® 4747 is formulated from a mixture of high-quality synthetic base oils (PAO & ester) and a lithium complex thickener, with corrosion inhibitors and antioxidants for long service life. The load carrying, antiwear and friction reducing capabilities of CASTROL TRIBOL® 4747 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 optimised.

Application

CASTROL TRIBOL® 4747 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® 4747 grease should be used when loads are moderate to heavy and speeds are slow to moderate.

 

Conditions of Use

  • CASTROL TRIBOL® 4747 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® 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.

 

Advantages

  • CASTROL TRIBOL® 4747 with TGOA® offers increased load carrying capabilities due to higher viscosity base oils and surface smoothing as well as friction reducing properties of TGOA®.
  • The lithium complex thickener is characterised 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.
