Supreme Lube (#268) is a multi-purpose thermally stable and thermally durable synthetic blend gear lubricant that is recommended for use in all types of enclosed industrial and automotive gear drives where extreme pressure characteristics are needed.
Supreme Lube is blended from the finest high quality severely solvent refined, severely hydro-finished high viscosity index 100% pure paraffin base oils and severely hydrotreated polyalphaolefin (PAO) synthetic base fluids available that provide it with the following advantages:
- Excellent low temperature properties. This results in the bearings and gears being instantly lubricated at sub-zero temperatures the moment they start turning.
- Superior oxidation stability.
- Excellent resistance to thermal degradation.
- Excellent hydrolytic and demulsibility characteristics.
- A high viscosity index.
- Increased wear protection and longer gear life.
- Compatibility with all types of seals.
Blended into these 100% pure paraffin base oils and PAO synthetic base fluids is a highly specialized non-corrosive thermally stable and thermally durable multifunctional extreme pressure additive package that provides the Supreme Gear Lube with the following performance advantages:
- Enhanced thermal and oxidative stability and durability to handle operating temperatures of 300- 350°F.
- Excellent extreme pressure properties to protect the gears and bearings from excessive wear and fatigue.
- Prevention of the formation of sludge and carbon deposits that erode the seals.
- Excellent seal compatibility.
- Enhanced protection of copper, brass and bronze components from corrosion.
- Non-corrosivity to brass, bronze and other non-ferrous metal parts.
- Excellent protection of components from rust and corrosion in dry conditions and in the presence of moisture.
- Excellent resistance to water and moisture.
- Excellent water separatibility characteristics.
- Enhanced gear, bearing and seal cleanliness.
- Excellent resistance to foaming.
Trends in automotive transmissions
The trend among automotive and industrial gear drive manufacturers is to operate the equipment at higher speeds, loads, power densities and increased torque. This trend has resulted in automotive and industrial gear drives being subjected to higher operating temperatures. These higher operating temperatures have resulted in today’s gear lubricant’s being subjected to extreme thermal stress.
The problem with conventional lubes
Therefore, it is important that a gear lubricant possess thermal stability and durability characteristics. Gear lubricants that do not possess these properties rapidly oxidize and decompose when subjected to high temperatures, resulting in the formation of sludge, varnish, and carbon deposits on the gears, bearings and seals, abraded seals, premature seal hardening and brittleness, and a loss of the gear lubricant’s extreme pressure additive chemistries ability to protect against excessive wear, spalling and overall distress to the gears and bearings.
The Schaeffer Solution
Supreme Gear Lube’s severely solvent refined, severely hydro-finished high viscosity index, 100% pure paraffin base oils and PAO synthetic base fluid and the thermally stable and the thermally durable multifunctional extreme pressure additive package enables the Supreme Gear Lube to resist oxidation and thermal stress at operating temperatures 150 ° F to 175 ° F higher than conventional gear lubricants. This can result in:
- A vast reduction in the formation of deposits.
- Better heat transfer.
- Excellent protection to the gears and bearings even under the most extreme thermally stressed operating conditions.
- Less wear to gears, bearings and seals.
- Increased oil seal life.
- Lower operating temperatures.
- Less energy consumption.
- Longer lubricant life.
- Longer equipment life.
- Reduced maintenance costs.
The problem with most lubes:
Most types of gearing are designed to operate under hydrodynamic lubrication conditions. That is a full fluid oil film must separate the metal surfaces of the gears and bearings during operation. However, during periods of cold start up, extremely high operating temperatures or high shock loading conditions this full fluid film can be destroyed. Unless a boundary lubricant is present in the gear lubricant when this full fluid film is destroyed, excessive wear can take place.
How Molybdenum Disulfide helps
To prevent this wear, Molybdenum Disulfide is further blended into the Supreme Gear Lube. Molybdenum Disulfide provides the boundary lubrication that is needed by plating itself to the metal surfaces of the gears and bearings. Once plated, Molybdenum Disulfide forms an indestructible long lasting solid lubricant film that is capable of withstanding pressures up to 500,000 psi. This solid lubricant film once plated to the gears and bearings will reduce friction, vibration, and wear, thus extending equipment life.
The Moly film also provides a smooth finish surface on all of the moving surfaces of the gear drives. This smooth finish minimizes the action of cold welding and vibration, which can occur during start up after the gears have been standing idle and during periods of high shock loading. This in turn lessens starting loads and peak power demand, thus resulting in a realistic power cost savings.
Supreme Gear Lube contains adhesive-cohesive additives that allow the product to tenaciously stick and cling to the gears and bearings. This ensures the Supreme Gear Lube to retain a fine film that “stays put” on the metal surface of the gears and bearings regardless of how thoroughly it is wiped away.
It also contains the proper additive system that allows the product to properly function and lubricate limited slip, positraction, and high offset gear rear ends and differentials.
