PRODUCT DESCRIPTION
AMSOIL GLB multi-purpose, EP grease is qualified against the highest grease standards, NLGI GC (wheel bearing) and LB (chassis), and is designed for multiple use applications. This grease is composed of synthetic base oils and lithium complex thickeners that provide the film strength, shear resistance and mechanical stability required for good grease lubrication. This combination excels in high and low operating temperature ranges by providing excellent oxidation stability, high temperature dropping points, good low temperature torque values and good low temperature pumping capabilities. GLB Grease is compounded with an effective oil soluble extreme-pressure additive for heavy loads, plus oxidation and corrosion inhibitors that impart good oxidation stability and rust protection.
AMSOIL's top performing lithium complex thickener system provides excellent adhesion properties and water resistance as identified by ASTM D-1264 water washout test. This resistance to water means a protective film of lubricant remains present to protect equipment against wear while the corrosion inhibitors prevent rust. AMSOIL GL Greases adhere to metal in all types of environments and they resist squeeze out during operation. These qualities ensure maximum lubricant protection during harsh operations.
AMSOIL GLB multi-purpose grease is recommended for many different applications. Its diversity simplifies lubricant inventories and prevents greasing errors while providing problem-free operation. AMSOIL GLB Grease reduce repair and maintenance costs.
PERFORMANCE FEATURES
- High dropping point of 500 ° F
- Resists thermal and oxidation degradation (lasts longer than conventional grease)
- Excellent water-washout resistance
- Good low temperature pumpability and torque values
- Adhesive and shear stable to prevent squeeze out
APPLICATION RECOMMENDATION
AMSOIL GLB Grease grade #1 is recommended for use in manual or automatic lubricating systems. NLGI #1 (GLB) has better mobility and is the preferred choice for colder applications, for automatic lubrication systems with long pumping runs, and for gear box applications (where recommended by manufacturer).
The correct consistency grade of AMSOIL GL multi-purpose greases are recommended for use in heavy and light duty applications found in manufacturing plants, automotive applications, agricultural equipment and construction equipment. These include, but are not limited to, roller bearings, plain bearings, thrust bearings, gears, electric motors, presses, winches, bushings, wheel bearings. chassis lubrication, universal joints, ball joints, tie-rod ends, and steering knuckles. AMSOIL GL greases are suitable for use up to 350 F When operating at elevated temperatures, frequent regreasing may be required.
AMSOIL GL Lithium Complex Greases are compatible with many other types of greases. However, it is recommended that when changing greases, the equipment be cleaned of the old grease when possible or flushed with a liberal amount of the GL grease while the mechanism is in operation. Closely monitor the system for any inconsistencies. Grease compatibility questions should be referred to your AMSOIL representative or AMSOIL Inc.
APPLICATION MAINTENANCE
Maintaining a clean work environment is important when equipment greasing is performed. Wipe grease fitting clean prior to injecting grease to prevent contaminant ingestion. Maintain bearing housings one-third to one-half full of grease. Do not over-grease, as excessive heat buildup can result. Supplement standard grease maintenance by periodically cleaning and packing housings with fresh grease on an established maintenance schedule.
