SAE 85W-140 Gear Oil


SAE 85W-140 Gear Oil is a state-of-the-art heavy-duty oil that is engineered with a solid dry film lubricant known as molybdenum disulfide. Over 96 years of lubricant experience and technology has gone into designing this extreme pressure heavy-duty gear lube that will provide amazing protection against severe shock loads and extreme pressure, all the while helping to reduce energy consumption and extend the life of all gear sets and bearings through long service life. SAE 85W-140 Gear Oil will protect at low and high speeds due to its superior high film strength, adhesive/cohesive capabilities, and amazing water separation properties.

Only the absolute finest high-performance base stock oils are chosen for SAE 85W-140 Gear Oil. These high viscosity paraffinic base stock oils offer superior thermal stability and are devoid of any unwanted impurities that could cause damaging deposits. These base oils are extremely resistant to oxidation and can function regardless of the temperature range it is asked to perform, no matter how cold or how hot. These high film strength base stocks, coupled with its high thermal stability, help to control any heat and dissipate that heat evenly throughout the unit case, thus making this gear oil a fantastic lubricant to protect your gear sets and bearings.

SAE 85W-140 Gear Oil is engineered to handle extreme conditions such as extreme pressure. Through its advanced additive chemistry, it easily can handle heavy shock loads that gears and bearings are subjected to. Its unique formulation contains high-performance sulfur phosphorous additives that are non-toxic and non-corrosive. This specialized sulfur and phosphorus chemistry is engineered to react under pressure and heat to create onto the metal surfaces a tenacious lubricating wear-resisting coating. This microscopically thin coating imparts a superior load-bearing surface that acts as a self-perpetuating lubricant. To prove its superior extreme pressure capabilities, it was put through the L-37 and L-42 Axel tests. After the tests were run, the results were astounding. It showed superior ability to protect gear sets, confirming that SAE 85W-140 Gear Oil provides exceptional lubrication for any gears and associated gear components.

SAE 85W-140 Gear Oil was engineered to avoid and reduce dry starts and also to impart qualities that have the gear oil clinging to all gear components. Its formulation provides it with superior adhesion and cohesion qualities. This clingability and tackiness property prevent any excess dripping and splattering of the gear oil and helps to maintain a tenacious coating upon the gear teeth which will resist any centrifugal force removing the protective lubricant. This advanced chemistry provides the necessary protection while bearings and gears are in operation. When equipment sits idle, all critical components are still protected, even during dry start-ups. Regardless of the situation, SAE 85W-140 Gear Oil works 24/7 by giving a tenacious coating of lubricant on all gear teeth and components, thus reducing and preventing any potential excessive wear. Regardless of whether there is moisture present, SAE 85W-140 Gear Oil’s tough coating on all critical metal parts will guard against any corrosion, rust, or wear.

Foaming can be a big problem for gear units. Under normal operating conditions, enclosed gears are usually partly submerged in gear oil. Over a period of operation, foam starts to appear and then the level of gear oil drops, which unfortunately causes the gears to be running dry. This self-defeating situation is counterproductive for the gear lubricant. Understand that foam is insulation, and if too much foam is found in a gear case, it will trap the heat rather than allow the gear oil to dissipate and transfer heat away. If this foaming goes unchecked or untreated, temperatures will start to soar, causing the distortion of metals, blown seals, and inadequate protection for all critical gear parts and bearings. This foaming issue can be eliminated through the use of SAE 85W-140 Gear Oil. It is formulated with robust volumes of the finest foam inhibitors that keep foaming at an absolute bare minimum. In fact, it was put through the ASTM D-892 Foam Test, and of course, it showed no tendency to foam. Proof in the pudding that SAE 85W-140 Gear Oil will keep your gear unit running cool and for a long time.

Blended into the high VI base stock oils and state-of-the-art gear oil chemistry is a proven and extremely effective dry film lubricant known as molybdenum disulfide or MoS2. This one-of-a-kind mineral compound plates to all metal surfaces, providing an extremely slippery film that will vastly reduce friction. Many years of testing has been performed in laboratories worldwide, and consistently it has been found that Moly can withstand extreme pressures as high as 500,000 pounds per square inch. This massive extreme pressure capability is way beyond the yield strength of most metals without causing any seizing or galling. This high-performance gear oil, if it did not have Moly, cold still outperform all conventional gear oils. The fact is, it does have Moly, which you greatly benefit from by getting an additional and definite advantage when operating conditions bring extremely high shocks loads and extreme pressure that go beyond the capabilities of normal lubricating films which may not be able to handle the pressure. In these extreme conditions, you can feel secure that critical gear components will be able to handle any situation knowing that it is lubricated with molybdenum disulfide.

SAE 85W-140 Gear Oil offers superior protection against water and moisture. Regardless of how tightly sealed as gearcase is, moisture and water tend to form due to the never-ending cycle of heating and cooling the equipment is exposed to. The everyday day and night cycle will create excessive moisture buildup due simply to condensation forming. Moisture can and will create rusting and corrosion. If this constant buildup of moisture is left unchecked, it can and will lead to inadequate protection because it will not allow the gear oil to effectively coat all the metal surfaces. To show the superior performance capabilities of protecting against moisture corrosion engineered into SAE 85W-140 Gear Oil, it was put through a 7-day moisture corrosion Axel test. At the end of the test, results indicated that it will provide superior protection against moisture corrosion.
