Unformatted text preview: : A Tribology Handbook. Butterworth-Heinemann Ltd., Oxford, England (b) At this stage, viscosity grouping can be made. For instance, if three similar oils have viscosities of 110, 150, and 190 SUS at 100 EF, the 150 may be used as a final selection. If one of the original oils was rust and oxidation inhibited, the final product should also have this property. A second group of oils with viscosities of 280, 330, and 350 SUS at 100 EF could be reduced to one oil having a viscosity in the neighborhood of 315 SUS at 100 EF. As shown in Figure 13-1, the goal is to identify the viscosity requirements and range for various equipment and see if a single lubricant can span the range. If the range can be covered, then consolidation is possible. However, recall that paragraph 13-3 included a warning that the lubricant viscosity for a machine must comply with the manufacturer’s requirements. Obviously, an exact match of viscosity for all equipment cannot be accomplished with the same lubricant when consolidation is the goal. Lubricants with vastly different viscosity requirements must not be consolidated. (3) Use higher quality lubricants. Another alternative for consolidation is to use higher grade lubricants that are capable of meeting the requirements of various machinery. Although the cost of highgrade lubricants is greater, this may still be offset by the benefits of consolidation (e.g., reduction in the number of different lubricants needed, reduction in inventory-management requirements, possible price discounts for purchasing certain lubricants in greater quantity, etc.). (4) Use multipurpose lubricants. Multipurpose lubricants and other general purpose oils can be applied to a wide range of equipment and help reduce the number of lubricants required. Although some lubricants are not listed as multipurpose they may be used in this capacity. For example, assume two lubricants by the same producer: one is listed as an R&O turbine oil and the other as a gear oil. 13-12 EM 1110-2-1424 28 Feb 99 Examination of product literature shows that the R&O turbine oil can also be used in bearings, gear sets, compressors, hydraulic systems, machine tools, electric motors, and roller chains while the gear oil can also be used in circulating system, chain drives, plain and antifriction bearings, and slides. These oils may be suitable for use in a consolidating effort. Producers often have similar application overlaps in their product lines. 13-13...
