Gear Oil: RPL-K Series

Series Range:

Product Description:

The RPL-K series gear oil is a semi-synthetic, EP, non-leak, MoS² fortified gear oil that is formulated using highly refined, hydro-treated paraffin base oils and synthetic PAO fluids with special additives to provide excellent EP and anti-wear performance.

At start-up, typical conventional gear oils have a tendency to push lubricants to the side of a gearbox by the centrifugal force of the rotating gears. As the gears turn, the splashing action eventually provides lubrication. But at start-up, when the metal-to-metal wear is the generally the greatest, the gears lack sufficient lubrication. The RPL-K gear oils are different. Immediately when the gears start, the RPL-K gear oils adhere to the gear teeth, and by resisting centrifugal force, they coat the gears from the outset providing a protective film of lubrication right from the initial critical moments.

The RPL-K gear oils are tacky. They contain a shear stable tackifier for extra-adhesive to prevent drip-drown, leak and splatter. Gear box leakage is also virtually eliminated, especially when there are worn seals. The overall result is a noticeable reduction in overall oil consumption. As well, the oil film resists fling during high-speed operations and will remain on the gears while the machine is idle.

All RPL-K gear oils contain a stable colloidal suspension of Molybdenum disulfide (MoS²), an additive that helps forms a thin protective layer of solid particles on metal surfaces and fills in the microscopic peaks and valleys (asperities) that are always present on metal surfaces, no matter how highly polished or machined. Then, acting essentially like tiny ball bearings, the MoS² will "roll" the load up to 500,000 pounds per square inch, preventing metal-to-metal contact and thereby reducing friction and wear.

RPL-K gear oils are also formulated to resist the formation of acidic by-products that tend to cause soft sludge deposits or hard varnish and lacquer coatings to form on the metal surfaces. These deposits lead to friction, increased heat, increased energy consumption and eventually the possibility of premature equipment breakdown.

The RPL-K gear oils are used in a wide variety of industrial and mobile equipment including mining, material processing, cement manufacturing, construction, steel and paper mills, tile, insulation, glass and textile manufacturing, farm machinery, printing and binding machinery, elevators, escalators and process mixing equipment. They provide superior lubrication for enclosed gear drives and reducers from fractional horsepower gear motors to large high horsepower units on metal rolling mills and mine hoists using a wide variety of gears including spur, bevel, herringbone and worm gear. They are recommended for lubrication of industrial hypoid type gears, gears subject to shock loading, transmission gear cases and worm drive axles on mobile contractor type equipment, open pit and underground mine machinery where highly loaded components such as reduction or power transmitting gears are protected.

Features and Benefits:

• High EP and anti-wear properties

• Excellent film strength and adhesion to metal surfaces

• Tacky for extra-adhesive properties

• High viscosity indices

• Superior rust and corrosion protection

• Non-foaming

• Excellent demulsibility - separates readily from water

• High temperature oxidation and thermal stability

• Long lubricant life, extended oil drain intervals

• Non-corrosive to copper, bronze and other non-ferrous parts of gear sets

• Reduced friction, lower operating temperatures and decreased power consumption especially in heavily loaded gear sets – up to 20 F reduction in temperature and 5% energy efficiency improvement

• Multi-Grade: one grade of oil can be used over a wider load-carrying range

Typical Operating Properties:

Method of Application:

No special precautions are required.  Follow regular maintenance instructions as provided with original equipment.  Although the RPL-K gear oils are formulated to be compatible with conventional oils, it is discouraged in particular due to the potential adverse effect on the additives such as competition, dilution, and a number of other factors.  it is recommended to thoroughly drain and clean systems prior to switching over. 

The proper type of grade of gear oil is important to the performance and life of a gear set. Selection of the correct lubricant viscosity is based on speed, load, operating temperatures and gear geometry.

All RPL-K gear oils meet or exceed the performance requirements of US Steel 224 and AGMA 250.04 and AGMA 251.02 specifications for industrial gear oil.
