AMSOIL Product Code: rc_series

Product Application
AMSOIL Synthetic RC Series Oils are primarily recommended for gear and bearing applications and circulating systems requiring R&O and/or antiwear additive technology.

RCE is a clear, nonstaining oil with an ISO-10 viscosity designed for high-speed spindles such as those found in textile applications.

The lighter viscosity RC Series Oils (RCF-RCH) provide superior protection in high- and low-pressure gear, vane and piston hydraulic systems, compressors, high-speed bearings, small gear sets, pumps, high-speed spindles, high-speed gears and many other industrial applications. Higher viscosity RC Series Oils, beginning with RCI (ISO 46), meet AGMA specifications for R&O and Synthetic gear oil specifications 1 through 8, respectively, for the lubrication of intermediate-speed equipment where mild shock loading and intermittent service are involved. These applications include machine tools, roller chains, gear reducers, cone drives, large motor bearings, medium-speed ball and roller bearings, blowers and worm gear sets. Consult the manufacturer for proper viscosity recommendations. The ability of RC Series Oils to extend drain intervals is subject to operating conditions and maintenance practices and should be monitored by oil analysis.

Although AMSOIL lubricants are compatible with mineral oil-based lubricants, for optimum performance it is recommended that the system be thoroughly drained and cleaned, if warranted.

Note: AMSOIL RC Series Oils are not designed for applications requiring Extreme Pressure (EP) agents. For EP fortified lubricants, refer to AMSOIL SG Series Gear Oils.

Product Description
AMSOIL Synthetic RC Series R&O/AW Gear and Bearing Oils are formulated with high-quality synthetic base stocks and additive systems that effectively reduce wear and protect equipment by maintaining viscosity, resisting thermal and oxidative breakdown, inhibiting rust and resisting the degrading effects of water.

Viscosity Characteristics
AMSOIL RC Series Oils are very shear-stable and oxidation-resistant, preventing viscosity loss from mechanical shear and viscosity increase from oxidation. RC Series Oils remain fluid at cold temperatures, providing easier startups, quick lubrication circulation and limiting the need for sump heaters. At higher temperatures, RC Series Oils maintain a thick lubricating film, reducing metal-to-metal contact and component wear.

Additive Performance
AMSOIL RC Series Oils are formulated with complete additive technology to enhance performance. Nondetergent, ashless antiwear additives provide an additional layer of protection against wear in severe conditions, rust inhibitors protect critical components against corrosion in the presence of water or process contaminants, antioxidants increase oxidation resistance and extend lubricant life and foam suppressants prevent foaming and air entrapment.

Water Resistant
RC Series Oils provide hydrolytic stability (stability in the presence of water) and demulsibility (ability to separate from water), increasing lubricant life, preventing oil/water emulsions and allowing reservoirs to be drained of water.

Performance Features

  • Extended oil drain intervals and equipment life
  • Yellow metals compatible
  • Resitant to high-temperature oxidation
  • Formulated with anti-wear, anti-rust and anti-foam additives
  • Excellent cold-temperature performance
  • Readily separate from water

AMSOIL industrial lubricants are formulated to meet or exceed accepted industry specifications. AMSOIL warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL products are used in full compliance with the company’s recommendations. However, the purchaser of these lubricants is responsible for determining if these specifications are adequate and proper for the intended application. The AMSOIL warranty is limited to lubricant performance consistent with indicated specifications. No additional warranty, expressed or implied, can be made.

AMSOIL products are available in 5-gallon pails, 55- gallon drums, 275-gallon totes and bulk quantities. For 275- gallon totes, please allow two to four weeks for delivery. AMSOIL Industrial Lubricants are stocked in Superior, Wisconsin and in select regional distribution centers throughout the United States and Canada. AMSOIL will stock additional quantities of lubricants or special order products based on customer requests and regional demands.
