GREASE HPL TRIBOL GR 4747/220-2 HT

CASTROL TRIBOL™ GR 4747/220-2 HT (formerly Tribol™ 4747/220-2) High Temperature Grease with TGOA™ is a multi-purpose clear lubricant designed to extend bearing life in heavy-duty and high-temperature applications.
Thanks to the high viscosity of its base oil, CASTROL TRIBOL GR 4747/220-2 HT provides a denser oil film for applications at low speeds, high loads and/or high temperatures.
Patented TGOA additive technology, in these harsh conditions, offers unsurpassed protection against friction and wear.
CASTROL TRIBOL GR 4747/220-2 HT is formulated with a blend of high-quality synthetic base oils (PAO and ester) and a lithium complex thickener.
In addition, it contains corrosion inhibitors and antioxidants for a longer service life.
The loading, anti-wear and friction-reducing capabilities of CASTROL TRIBOL GR 4747/220-2 HT exceed those of conventional complex greases.
Its high performance is due to the TGOA additives which, under relatively high specific loads and at the corresponding temperatures, promote a non-destructive smoothing of surface roughness at the microscopic level.
This smoothing effect increases the effective contact surface and reduces friction.
TGOA additives are very effective in protecting the machined surface of bearings during the critical break-in period.
Healthy bearing surfaces are essential for a long service life.
If, due to impact loads or intermittent operation, new peaks in surface roughness occur, the TGOA® additive package is automatically reactivated.
The surface roughness is smoothed again and lubrication is optimized.
