Best Grease for Equipment | How to Choose Grease

Several considerations, including grease quality and thickener form, as well as operating conditions, affect grease selection. Here’s everything you need to know to figure out what the best grease for equipment is and the kind of grease you require for your specific application.

What exactly is grease?

Grease is composed of three primary components:

  • Thickeners
  • Base oil
  • Additives

A grease penetration designation is used by the National Lubricating Grease Institute (NLGI). You’ve most likely already seen NLGI #2 grease at some point.

The most common designation is NLGI #2, which is used in many automobile and heavy-duty applications, including ball joints and other suspension parts.

NLGI numbers range from NLGI #000, which has a consistency similar to cooking oil, to NLGI #6, whose consistency is like cheddar cheese.

Grease performance requirements

When deciding on the kind of grease you require, keep the necessary specifications in mind. There are performance standards in the grease industry for wheel bearing greases (GA, GB & GC) and chassis greases (LA & LB).

The designation GC-LB indicates that the grease has passed the most stringent test criteria for chassis parts and wheel bearings. Greases that follow the GC-LB specification usually meet the specifications of the majority of automotive original equipment manufacturers.

What type of grease do I require?

Some of the factors that influence grease selection are…

  • Type of thickener
  • Dropping point
  • Consistency
  • Worked stability
  • Temperature range
  • Resistance to wear
  • Stability of oxidation

The viscosity of a lubricant is its most valuable attribute. The viscosity of oil is usually selected depending on the application criteria.

When choosing a grease, it is popular to confuse the consistency of the grease with the viscosity of the base oil.

When choosing a grease, take into account the use, speeds, environment, loads, and OEM guidelines.

Following are some common grease applications and the appropriate grease to use for each.

Rotating bearings

This category includes (but is not limited to)…

  • Plain bearings
  • Roller bearings
  • Gears
  • Thrust bearings
  • Motors that run on electricity
  • Presses
  • Bushings
  • Winches
  • Wheel bearings
  • Lubrication of the chassis
  • Universal joints 
  • Universal joints 
  • Ball joints
  • Steering knuckles

These parts are widely used in light- and heavy-duty applications encountered in manufacturing facilities, automobiles, landscaping equipment, powersports equipment, agricultural machinery, and trailers.

AMSOIL Synthetic Multi-Purpose Grease, Synthetic Water-Resistant Grease, and DOMINATOR® Synthetic Racing Grease are all excellent multi-use greases.

Bearings that are subjected to high-impact loads

These parts include (but are not limited to) highly loaded…

  • Grease points on the chassis
  • Wheel bearings
  • Universal joints
  • Axel components
  • Steering linkages
  • Pivot pins
  • King pins
  • Spring pins
  • Bearings for water pumps
  • Ball joints
  • Other heavy-duty greased parts

These applications necessitate the use of specialty greases designed for heavy-duty machinery exposed to harsh service environments. Such grease is intended to provide extra protection above and beyond that provided by a multi-purpose grease.

These uses are ideal for AMSOIL Synthetic Polymeric Truck, Chassis, and Equipment Grease and High-Viscosity Lithium-Complex Synthetic Grease.

Sliding applications and non-rotating bearings

These applications comprise (but are not limited to) highly loaded…

  • King pins
  • Pivot pins
  • Bushings
  • Bucket pins
  • Plates for fifth-wheel hitches

Greases developed for these applications are intended to offer increased protection, tackiness, and impact resistance than a multi-purpose grease would. They are specialty greases that define the type of operation, such as heavy load bearing, as well as the harsh circumstances that these applications are subjected to.

AMSOIL Synthetic Polymeric Off-Road Grease and AMSOIL Synthetic Fifth-Wheel Grease are both outstanding options.

Applications for specialized use

These include machinery used in the pharmaceutical and food service sectors. They frequently need NSF-Approved grease, such as AMSOIL X-Treme Synthetic Food Grade Grease, which is engineered to operate at a wide range of temperatures.

Some uses, such as arctic drilling platforms, necessitate a grease of excellent cold-weather pumpability. Most greases are not engineered for exceptionally low temperatures and struggle to pump and defend in sub-zero temperatures. AMSOIL Arctic Synthetic Grease is engineered to work and protect in extremely cold temperatures.

Hopefully, this blog post has assisted you in determining the best grease for equipment and what kind of grease you need for your specific application.
