Gear Oil: RPL-GL Series

Series Range:

• RPL-GL68 • RPL-GL220 • RPL-GL680
• RPL-GL100 • RPL-GL320  
• RPL-GL150 • RPL-GL460  


Product Description:

The RPL-GL series gear oil is formulated using highly refined, hydro-treated paraffin base oils with special additives to protect heavily loaded bearings and gear sets for industrial lubrication. These additives provide high EP properties for high load carrying ability which greatly reduces wear. They also provide enhanced oxidation and thermal stability which resists the formation of acidic by-products including soft sludge deposits and hard varnish or lacquer coatings on metal surfaces, especially at higher operating temperatures. These deposits lead to friction, increased heat, increased energy consumption and eventually the possibility of premature equipment breakdown.

The RPL-GL 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.

The RPL-GL gear oils are used in a wide variety of industrial and mobile equipment including enclosed gear systems, chain drives, sprockets, plain and roller bearings, slide guides, flexible couplings, cams and open chains. 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.

Features and Benefits:

• High EP and anti-wear properties
• Excellent rust protection
• Non-corrosive to copper, bronze and other non-ferrous gear sets
• Non-foaming
• Good demulsibility - separates readily from water
• High temperature oxidation and thermal stability
• Long lubricant life
• Extended oil drain intervals

Method of Application:

No special precautions are required. Follow regular maintenance instructions as provided with original equipment. Although the RPL-GL gear oils are compatible with conventional oils, 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.

RPL-GL gear oils are recommended for the lubrication of industrial hypoid type gears, for gears subjected to shock loading, transmission gear cases and worm drive axles on mobile contractor type equipment, open pit and underground mining machinery.

All RPL-GL 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.
