AMSOIL Synthetic Multi-Purpose Grease (GLC)

Synthetic Multi-Purpose Grease, NLGI #2 (GLC)

AMSOIL Synthetic Multi-Purpose Grease grade #2 is recommended in manual or automatic lubricating systems.

NLGI #2 (GLC) is the preferred choice for medium to high ambient temperatures, sleeve type bushings, high shock loading environments, wet environments and wheel bearings and other automotive applications.

The correct consistency grade of AMSOIL Synthetic Multi-Purpose Grease is recommended in heavy and light duty applications found in manufacturing plants, automobiles, agricultural 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 Synthetic Multi-Purpose Greases are suitable for use up to 350° F. When operating at elevated temperatures, frequent regreasing may be required.

AMSOIL Synthetic Multi-Purpose 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 Multi-Purpose 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 Recommendation

AMSOIL GLC Greases grade #2 is recommended for use in manual or automatic lubricating systems. NLGI #2 (GLC) is the preferred choice for medium to high ambient temperatures, sleeve type bushings, high shock loading environments, wet environments, and is the primary choice for wheel bearings.

The correct consistency grade of AMSOIL Heavy Duty EP Grease is 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, gears, bushings, wheel bearings, chassis lubrication, universal joints, ball joints, tie-rod ends, steering knuckles, and heavily loaded pivot pins on mining and off road equipment such as power shovels, draglines, wheel and back hoe loaders, excavators and bulldozers. AMSOIL Heavy Duty EP Greases are suitable for use up to 325° F. When operating at elevated temperatures, frequent regreasing may be required.

AMSOIL GL Lithium Complex Greases are compatible with many other types of grease. 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. Any 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 fittings 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.

AMSOIL GL Series Greases are available in 8-oz. tubes, 14-oz. cartridges, 35-lb. pails, 120-lb. kegs and 400-lb. drums. AMSOIL Industrial Lubricants are stocked in Superior, Wisconsin and in select regional distribution centers throughout the United States and Canada. AMSOIL will stock additional quantities of lubricants or special order products based on customer requests and regional demands.
