Description

Supreme Gear Lube No Tack (#293A) is a multipurpose thermally stable and thermally durable para-synthetic gear lubricant that is recommended for use in all types of enclosed industrial gear drives that contain filtration systems where an extreme pressure characteristics are needed.

Supreme Gear Lube No Tack is blended from the finest high quality severely hydro-treated polyalphaolefin (PAO) synthetic base fluids and severely solvent refined, severely hydro-finished high viscosity index 100% pure paraffin base oils available. This unique combination provides Supreme Gear Lube No Tack 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 para-synthetic base fluids is a highly specialized non-corrosive thermally stable and thermally durable multi-functional extreme pressure additive package that provides the Supreme Gear Lube No Tack with the following performance advantages:

  • Enhanced thermal and oxidative stability and durability to handle operating temperatures of 300°F to 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.

The trends among industrial gear drive manufacturers is to operate the equipment at higher speeds, loads, power densities and increased torque. These trends have 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. 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.

Supreme Gear Lube No Tack’s para-synthetic base fluids and the thermally stable and thermally durable multi-functional extreme pressure additive package enables the Supreme Gear Lube No Tack to resist oxidation and thermal stress at operating temperatures 150ºF to 175ºF higher than conventional gear lubricants.

The problem with conventional gear lubricants

Most types of gearings 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.

Schaeffer’s solution

Supreme Gear Lube No Tack contains a proven friction reducer and boundary called Micron Moly®. Micron Moly® is a liquid soluble type moly that plates itself to the metal surfaces of the gears and bearings. Once plated, Micron Moly® 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 Micron Moly® also provides a smooth finished surface on all moving parts of the gears. This minimizes the action of cold welding and vibration, which can occur during start up after 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.
