Note: Non-Cat commercial greases are as a group second choice greases. Within this grouping of second choice greases there are tiered levels of performance.
Cat does not warrant the quality or performance of non-Cat fluids and greases.
Caterpillar provides a family of grease products that vary in performance from moderate to high performance. These greases service the entire line of Cat products in the wide variety of climates throughout the world. From this variety of Cat grease products, you can find a Cat grease that will meet or exceed the performance requirements for almost every machine that is produced by any Original Equipment Manufacturer (OEM), and for almost every machine application or equipment application.Before selecting a grease product, the performance requirements must be determined. Consult the grease recommendations in your Operation and Maintenance Manual. Also, consult your Cat dealer for a list of greases that have the performance specifications and the available container sizes.This grease chapter refers to NLGI of the grease products offered by Caterpillar. The National Lubricating Grease Institute (NLGI) classifies the greases per their consistency or hardness according to "ASTM D4950" and "SAE J310". The higher the NLGI value the more firm the grease. NLGI is an important classification for greases and it should be used along with other properties such as stability, corrosion resistance, viscosity, etc.Note: Always choose grease that meets or exceeds the recommendations that are specified by the equipment manufacturer for the application.Some work sites require the use of a single grease to fulfill the needs of all the equipment. Always choose a grease that meets or exceeds the requirements of the most demanding application. Remember that commercial products which barely meet the minimum performance requirements can be expected to produce the minimum life for the parts. It is not recommended to purchase grease products based on the lowest cost as the only consideration. Instead, use the grease that yields the lowest total operating cost. This cost should be based on an analysis that includes the improved product life, costs of parts, labor, downtime, and the cost of the amount of grease that is required.Note: Certain Cat grease products are formulated with Molybdenum disulfide (MoS2 or “Moly”). The Moly used in Cat greases is of a technical fine grade. This size meets the special requirements of some rolling element bearings, joints, and other moving components of tight clearances.Note: When the grease in a joint is changed from one type of grease to another or a grease from a different supplier is to be used, the general recommendation is to purge all of the old grease from the joint. Some greases are not chemically compatible. Consult your supplier in order to determine if the greases are compatible.If in doubt, Purge!Note: All Cat greases are “chemically” compatible with each other. Mixing of Cat greases will not result in an adverse chemical reaction. However, mixing of Cat greases might result in reduced performance.Cat Utility Grease
Cat Utility Grease is formulated for use in applications that have a low severity to a medium severity and moderate temperatures. Cat Utility Grease is a National Lubricating Grease Institute (NLGI) grade 2 grease. This grease is made with petroleum base oil and a lithium complex thickener.Cat Utility Grease is formulated to offer a good service life in engine applications. Service Life refers to the percent of change after 100,000 strokes per "ASTM D217".For more information on Cat Utility Grease, refer to the product information on the package or to the data sheet of this product.Note: If the application calls for a utility grease and Cat Utility Grease is not available, consult the grease data sheets. Use a substitute that meets or exceeds the performance characteristics of Cat Utility Grease.Cat Ball Bearing Grease
This grease is recommended for applications that utilize roller bearings and ball bearings at low loads to moderate loads at high speed. Typical applications for this grease are electric motors, alternators, and constant velocity (CV) joints for automotive products. Cat Ball Bearing Grease is an NLGI grade 2 grease. This grease is made with petroleum base oil and polyurea thickener.Cat Ball Bearing Grease is formulated to offer very good service life in engine applications. Service Life refers to the percent of change after 100,000 strokes per "ASTM D217".Cat Ball Bearing Grease offers good corrosion protection and good water washout resistance. Corrosion protection is the resistance to salt water per "ASTM B1743". Water washout resistance refers to roll stability with water and the percent of change "ASTM D1264".For more information on Cat Ball Bearing Grease, refer to the product information on the package or to the data sheet of this product.Cat White Assembly Grease
Cat White Assembly Grease is formulated for use in applications that have low to medium severity and moderate temperatures. This grease has been made extra tacky in order to hold gaskets, O-rings, and needle bearings to aid in the assembly of engines, transmissions, and other components. Cat White Assembly Grease is an NLGI grade 2 grease. This grease is made with a petroleum base oil and a lithium complex thickener.Note: Cat grease products given above are applicable to marine engines. Refer to Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" for other Cat grease products that include extreme applications and can also be used in marine engines. Consult your Cat dealer for information and for availability.
