Castrol Tribol GR 4747/220-2 HT High-temperature grease 400g

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.ApplicationMulti-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.AdvantagesCASTROL 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.Technical specificationsThickener Type: Lithium complexWorked Penetration ASTM D217 / ISO 2137 0.1 mm: 265 – 295Dropping Point °C / °F: >250 / >482Base Oil Viscosity @ 40°C / 104°F mm²/s: 220Base Oil Viscosity @ 100°C / 212°F mm²/s: 25.4Viscosity Index: 146Flash Point – open cup method: °C / °F 280 / 536Volume: 18kg bucketAlso available in: 400g cartridge, 5kg bucket, 50kg barrel, 180kg barrelGLIS number: 157C4BMSDS code: 468701Additional InformationsCASTROL 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 ensurecomplete 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 inspectionDescriptionCASTROL 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 GR4747/220-2 HT, Castrol Tribol GR 4747 220-2 HT, Castrol Tribol GR 4747/220 2 HT Information on product safety (Manufacturer, Contact)BP Europa SE, Erkelenzer Straße 20, 41179 Mönchengladbach, GERMANY, +49 800 7235 074, , www.bp.com
