Industry gear oils
TRANSGEAR PAG
|
General features
Transgear PAG synthetic oils for industrial gears are manufactured basing on polyalkylene glycols. They were developed especially to work with extremely high loads and high temperature.
It is featured by:
ability to transfer extremely high loads,
high resistance to aging,
perfect anticorrosive protection (it is tough to ASTM D665 B procedure),
very good demulsifying characteristics,
compatibility with commonly used leak stoppers,
no content of chlorine, sulphur and lead compounds.
Transgear PAG oils are not compatible with mineral oils.
Application
Transgear PAG oils are intended to lubricate various devices and mechanisms working at the temperature up to 200°C including:
- heavy loaded mechanical gears of industrial devices, spur cylindrical gears, helical bevel gears, spiral bevel gears and worm gears exposed to heavy thermal loads,
- rolling bearings and slide bearings,
- piston compressors.
