Greases
Castrol Tribol 4020/460 Greases with TGOA? are elevated temperature,
multi-service greases designed to extend the service life of bearings in heavy
duty and elevated temperature applications.
TGOA is an additive package designed to reduce friction while providing
surface protection and improvement due to its unique action on frictional
surfaces. Because of the possible adverse effects on the environment, typical
materials of expressed concern: i.e., antimony, barium lead, zinc; are NOT use
in Castrol Tribol 4020/460 Greases.
Because of the ISO 460 base oil viscosity, Castrol Tribol 4020/460 Greases
provide a heavier oil film for applications at slower speeds, higher loads, and/or
higher temperatures.
Description
Castrol Tribol 4020/460 Greases are formulated from a petroleum base oil, al
lithium complex thickener, and TGOA, the latest advancement in the field of
friction and reducing and surface improving additive technology.
The load carrying, antiwear, and friction reducing capabilities of Castrol Tribol
4020/460 Greases exceed conventional complex greases. High performance is
the result of the TGOA additives which, under relatively high specific loads and
related temperatures, promote a nondestructive smoothing of surface
roughness in the microrange. This smoothing effect leads to an increase in the
actual load-bearing area and reduces friction.
The TGOA additives are very effective in protecting the machined surfaces 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 operations, surface roughness peaks
redevelop, the TGOA additive package automatically reactivates. Surface
roughness is again smoother and lubrication optimized.
Applications
Castrol Tribol 4020/460 Greases and 4020/460-2 Greases meet NLGI
consistency Grades 1 and 2 respectively. They are formulated from premium

petroleum base oil, ISO VG 460. Castrol Tribol 4020/460 Greases with TGOA
were formulated as multi-service lubricants for heavy-duty applications of plain
and antifriction bearings from medium to high loads. They are designed for
continuous operating temperatures up to 150°C/302°F, more frequent
reapplication is required to prevent deterioration of the petroleum base fluid.
Reapplication cycles should be established that insures the grease does
not stiffen in the bearing.
Advantages
Castrol Tribol 4020/460 Greases with TGOA offer:
? Increased load carrying capability: achieved by higher viscosity base oils
and surface smoothing and friction reducing properties of TGOA.
? Excellent temperature stability: dropping point over 238°C/460° F.
? Outstanding water washout characteristics and shear stability: as a result of
a highly stable, advanced lithium complex thickener in addition to special
highly controlled manufacturing techniques.
The TGOA additive technology provides these further advantages for bearings:
? Reduced friction and wear
? Reduced operating temperatures
? Reduced noise and
? Extended service life with reduced maintenance and repair costs.
Notes
Castrol Tribol 4020/460 Greases with TGOA should not be mixed with grease
using a different thickener.
At higher temperatures (above 100°C/212°F to 150°C/302°F) relubrication
intervals should be established by inspection. It is important that grease in
bearings remains pliable.
For temperature about 150°C/302°F, regular reapplication of Castrol Tribol
4020/460 Greases must be considered to prevent deterioration of the
petroleum base oil. For continuous service near 204°C/400°F, reapply Castrol
Tribol 4020/460 Greases daily or once each shift. Reapply before the grease in
the bearing stiffens.
For lower temperatures and/or higher speeds, Castrol Tribol 4020/460
Greases are available with a base oil viscosity of ISO VG 220.
