75W90-S, 80W90-S
Synthetic lubricant for gearboxes

Description

PROLAB's 75W90-S and 80W90-S products are synthetic oils for industrial gearboxes with exceptional properties: they outclass standard oils by their performance and durability.

Characteristics and Benefits

PROLAB's 75W90-S and 80W90-S synthetic oils for industrial gearboxes are the result of an innovative formulation that protects gears against wear caused by friction by covering metal surfaces of bearings, pinions and crankcases with a lubricant coating thus providing power transfer integrity, a much smoother operating mode and greater reliability and efficiency.  The 75W90-S and 80W90-S synthetic oils are particularly effective in gearboxes working with heavy loads and in extreme conditions.  They offer maximum protection against oxidation and corrosion, have built-in superior anti-foaming characteristics and remain fully effective in low temperature start-ups as well as in high temperature operation.

Types of Application

Use PROLAB's 75W90-S and 80W90-S synthetic oils in all types of industrial gearboxes, journal bearings or rolling-contact bearing.

Directions for Use

Follow the manufacturer's instructions for the lubrication of the specific piece of equipment.

Notes

For better results, it is highly recommended to use PROLAB's DE-25 Decontaminant prior to using a new lubricant.
