Castrol Tribol GR 4747/220-2 HT High-temperature grease 18kg bucket

Castrol Tribol™ GR 4747/220-2 HT high-temperature grease (NLGI grade 2) with TGOA™ is a clear multiservice lubricant designed to extend the service life of bearings in heavy-duty applications and at elevated temperatures.

Application

• 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.

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

Additional Informations

• 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

Description

• 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.
