CASTROL TRIBOL 800
Synthetic gear oils
DESCRIPTION
CASTROL TRIBOL?800 gear oils were developed for application in highly loaded gears and bearings even
when subjected to high operating conditions.
They differ from mineral oil-based gear oils in the following characteristics:
? they feature an excellent oxidation stability (even at high temperatures)
? outstanding viscosity-temperature stability and extremely high viscosity-index without using VI improvers
? they are manufactured from high-quality polyglycol base oils
? CASTROL TRIBOL?800 synthetic gear oils are available in the viscosity grades 100 to 1000
APPLICATION
? The excellent properties of CASTROL TRIBOL?800 synthetic gear oils are especially evident in the
lubrication of mechanically and/or thermally highly loaded friction surfaces.
? They are especially suited for service in highly loaded enclosed gear drives (spur, helical, bevel and worm
gears), the lubrication of rolling and sliding bearings in paper machines, PVC calanders, kneaders,
extruders and mills.
? Temperature Range: Sustained oil reservoir temperatures up to + 140癈/285癋, with short-time exposure
to peak temperatures up to 200癈/390癋.
ADVANTAGES
? Considerable decrease in maintenance costs due to a prolonged service life of lubricant and machine
parts (owing to the high oxidation resistance an extremely extended service life of mineral oils is
guaranteed)
? The good viscosity-temperature behavior ensures the formation of a load-resistant lubricating film on the
friction surfaces over a wide temperature range thus offering an optimum wear protection.
? Critical mixed-friction areas are easily coped with due to the efficiency of EP additives. These operating
conditions prevail under extremely high loads (e.g. shock loads), 搒top-and-go?operations as well as at
slow rolling and sliding speeds under high loads.
? Excellent corrosion protection and good foaming behavior.
? Compatibility with non-ferrous metals is guaranteed by appropriate additives.
? CASTROL TRIBOL?800 is classified according to API GL5 with regards to seizure.
NOTES FOR USE
? CASTROL TRIBOL?800 synthetic gear oils are not compatible with mineral oils. Therefore a thorough
cleaning of gearboxes, bearings and oil reservoirs are recommended.
? Condensation water may be absorbed without the danger of corrosion or a change in viscosity.
? CASTROL TRIBOL?800 synthetic gear oils are compatible with seals, e.g. NBR, FPM (other materials
on request).
? They are compatible with nearly all conventional one-component and two-component lacquers.
? Quality standard: CASTROL TRIBOL?800 synthetic gear oils are CLP-PG oils (acc. to DIN 51502) and
exceed the minimum requirements according to DIN 51517, T. 3 for CLP gear oils
