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. The high base oil viscosity of 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 provides for an unsurpassed protection against friction and wear in the conditions above.
