Description:

High Performance Gear Coupling Grease

Shell Gadus S2 High Speed Coupling Grease is specially formulated with a lithium soap/polymer thickener, which has superior resistance to oil separation when subjected to the high centrifugal forces normally found in couplings.

Performances, Features and Benefits:

•Resistance to centrifugal separation. 

•Extended relubrication frequency. 

•High load carrying capabilities. 

•Resistance to water washing. 

•Staying in place under high speeds. 

•Corrosion and rust protection. 

•Minimizing of coupling wear. 

•Reduction in down time and maintenance costs. 

•Minimizing of coupling freeze-up. 

•Use at temperatures up to 3250F 

•One grease for all grease coupling types. 

•Shell Gadus S2 High Speed Coupling Grease has a consistency which 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 an effective rust inhibitor additive package. 

•Its high viscosity base oil and tackifier combine to keep the grease in place and prevent separation. In the ASTM D 4425, High Speed Centrifugal Test, which develops G forces in excess of 36,000 at 15,000 rpm. Shell Gadus S2 High Speed Coupling Grease exhibits little or no oil separation. 

•Based on ASTM D 1478 and D 4693 torque tests, the minimum recommended bearing lubrication service would be - 

100F. For coupling service the minimum usable temperature is not dependent upon ease of pumping or bearing breakaway force. Field service confirms problem-free coupling service at - 

200F and below. Actual minimum temperature for coupling service would be below -200F. 

Application:

•Shell Gadus S2 High Speed Coupling Grease is recommended for all types of grease lubricated couplings used in industrial equipment. Common grease lubricated couplings include: 

•Geared Couplings which have internal and external spur gears that mesh within a common rotating hub connecting the shafts. 

•Steel Grid Couplings which have a convoluted band of flexible spring steel physically linking the hubs together. 

•Flexible Chain Couplings which have a roller chain that meshes with a sprocket cut in each mating hub. 

•Advanced technology has enabled Shell Gadus S2 High Speed Coupling Grease to perform beyond the normal 6 month change interval. In actual field experience this grease has shown its ability to perform satisfactorily beyond 3 years. This product should be used in all grease couplings, especially in those hard to service or those operating under severe conditions. 

•Because of its high base oil viscosity, Shell Gadus S2 High Speed Coupling Grease is also suitable for use in other industrial applications where the equipment is subject to high water wash, low speeds and heavy or shock loads.
