SHELL ALVANIA CG GREASE Shell Alvania Grease CG is specially formulated with a lithium soap/polymer thickener, which has excellent resistance to oil separation when subjected to the high centrifugal forces normally found in coupling applications. Application Shell Alvania Grease CG is suitable for all types of grease lubricated couplings used in industrial equipment. Common grease lubricated couplings include: 1. Geared Couplings that have internal and external spur gears that mesh within a common rotating hub connecting the shafts. 2. Steel Grid Couplings that have a convoluted band of flexible spring steel that wraps around the coupling hubs. Advanced technology has enabled Shell Alvania Grease CG to perform beyond the normal 6-month change interval. In actual field experience this grease has shown its ability to perform satisfactorily beyond 12 months in many applications. Because of its high base oil viscosity, Shell Alvania Grease CG is also suitable for use in other industrial applications where the equipment is subject to high water wash, low speeds and heavy or shock loading. Feature Shell Alvania Grease CG has a consistency that overlaps the NLGI grades 0 and 1. This grease is specially formulated with a lithium/polymer thickener and fortified with corrosion, oxidation, extreme pressure and antiwear additives. Its high viscosity base oil and tackifier combine to help keep the grease in place and prevent separation. In the ASTM D4425, High Speed Centrifugal Test, which develops G forces in excess of 36,000 at the test temperature, Shell Alvania Grease CG demonstrates excellent resistance to oil separation. Benefit • Resistance to centrifugal separation • Extended relubrication frequency • High load carrying capabilities • Resistance to water washout • Stays in place under high speed • Corrosion and rust protection Based on ASTM D 1478 and D 4693 torque tests, the minimum recommended bearing lubrication service would be -10°F. For coupling service the minimum usable temperature is not dependent upon ease of pumping, but rather on the ability of the grease to provide adequate lubrication at the operating temperature. Approvals and Recommendations • AGMA CG-1 type • AGMA CG-2 type • AGMA CG-3 type Shell Alvania® Grease CG is suitable in all types of grease couplings including the following: • Browning • Falk • Kop-Flex • Fast • TB Wood's Product Maintenance The tacky nature of the product makes hand packing the preferred method of newly installed couplings to ensure even distribution throughout. Normal handling precautions should be observed when working with this product.
