PRODUCT DESCRIPTION
SENTINEL® SPECIAL SYNTHETIC GEAR OILS ARE MULTI-PURPOSE SPECIALLY
COMPOUNDED MOLYBDENUM DISULFIDE GEAR LUBRICANTS FORMULATED TO
PROVIDE SUPERIOR FILM STRENGTH AND EXTREME PRESSURE PROPERTIES. THEY ARE
TRULY ANTI-FRICTION, ANTI-WEAR, ANTI-LEAK, ANTI-FOAM GEAR OILS. SENTINEL®
SPECIAL SYNTHETIC GEAR OILS ALSO SURPASS FZG STAGE 12, THE HIGHEST RATING
THAT CAN BE ATTAINED. THEY CAN BE USED AS MAKE-UP AND REFILL LUBRICANTS IN
ALL TYPES OF ENCLOSED GEAR MECHANISMS, INCLUDING SPUR, HERRINGBONE,
SPIRAL, BEVEL AND HYPOID. SENTINEL® GEAR OIL SERIES WILL ALSO ADEQUATELY
MEET AND SURPASS REQUIREMENTS OF HEAVY DUTY INDUSTRIAL TRANSMISSIONS
AND GEAR TRAINS SUBJECT TO HIGH LOAD AND IMPACT LOADS.
SENTINEL® SPECIAL SYNTHETIC GEAR OILS ARE FORMULATED TO GREATLY IMPROVE
THE VISCOSITY TEMPERATURE SLOPE. IN OTHER WORDS, THEY REDUCE THE CHANGE
IN VISCOSITY WITH INCREASE IN TEMPERATURE UNDER ISOTHERMAL CONDITIONS.
THE NONNEWTONIAN BEHAVIOR OF THESE LUBRICANTS HAVE SHOWN GREATER
REDUCTION IN FRICTION AND WEAR DUE TO MAINTAINING GREATER FILM THICKNESS
ON GEAR TEETH, THEREBY REDUCING AMPERAGE CONSUMPTION, AS WELL AS
REDUCING FRICTIONAL HEAT.
WHEN SEVERE RISE IN TEMPERATURE IS REACHED, THESE LUBRICANTS WILL CARRY
GREATER LOADS BECAUSE OF THE FLATTER VISCOSITY TEMPERATURE SLOPE. THE
NON-NEWTONIAN AS WELL AS THE NONFOAMING PROPERTIES OF THESE LUBRICANTS
PRACTICALLY ELIMINATE ALL LEAKAGE.
