Understanding the Differences between Automotive and Industrial Greases

“Our plant is searching for a new type of grease. Can you explain the differences between industrial and automotive greases in composition, features, and performance requirements or in any other aspect?”

 

In short, there is really no difference between automotive and industrial greases. Grease selection will depend on the desired application and performance.

 

In regards to grease and its application, there are critical elements used in the formulation process that must be considered. These elements include the thickener type and concentration, lubricant type, viscosity and additive package. Greases are rated by the National Lubricating Grease Institute (NLGI) and range from 000 through 6. An NLGI 2 grade is typically the specification used in automotive greases.

 

One of the only differences between industrial and automotive greases is that a two-letter designation is often used in the automotive industry to specify the type of grease to employ. For example, greases may be rated as GC or LB. GC is recommended for axle and wheel bearing grease, while LB is the industry standard for chassis grease used on tie-rod ends, ball joints, U-joints and control-arm shafts.

 

Regardless of the application, greases should reduce friction and wear, protect against corrosion, seal bearings from water and contaminants, and resist leakage. While one of the main reasons for grease failure is selecting the wrong type of grease for the intended application, there may also be other causes, such as incompatibility resulting in excessive softening of the grease, contamination leading to excessive wear or applying too little or too much grease for the application.

 

For instance, in off-road equipment, the environment generally is harsh with a variety of factors to take into account including water, dirt, poor seals and heavy loads. In this type of situation, grease selection is key. You will need a grease with good rust protection, film strength and water resistance.

 

Bearings normally see less contamination but often experience wide variations of speed and temperature. In this case, you should choose grease with excellent oxidation stability, exceptional mechanical stability and good performance over a wide temperature range.

 

In summary, the constituents of industrial and automotive greases may be quite similar and should be treated as such. The point is that no matter the application in which grease is used, it is critical to know how to properly select a grease while keeping in mind all of the important parameters.

What is a Hydraulic Power Pack Unit?

Hydraulic Power Pack Units are the main driving components of hydraulic systems. Consisting mainly of a motor, a reservoir and a hydraulic pump, these units can generate a tremendous amount of power to drive most any kind of hydraulic ram. Hydraulic power pack units are based on Pascal’s law of physics, drawing their power from ratios of area and pressure.

 

Hydraulic power pack units are used in a wide range of applications, including:

 

  • Machine Tools
  • Automation
  • Meat Processing Machinery
  • Mobile Equipment
  • Aerospace Test Equipment
  • Rolling Mill Machinery
  • Material Handling
  • Agricultural Equipment
  • Paper Mill Machinery
  • Government/Military
  • Oil Field
  • Oil Spill Clean Up Equipment
  • Industrial Process
  • Marine Equipment
  • Construction Equipment
  • Theatrical & Production Equipment

 

Hydraulic power pack units can generally be used in any application that requires heavy and systematic lifting or other requirements for the repeated use of powerful and directional force.

 

Consider all of the ways that hydraulic power pack units are used in things you see every day. Drive past any construction site and you’re likely to see some kind of heavy construction machine, be it a bull dozer, an excavator or even a skid steer. All of these machines rely on hydraulic power units to do their work. Fishermen rely on hydraulic power units to lift their nets and pots. Your auto mechanic uses a hydraulic power pack unit to lift your car high enough to walk around beneath it and make repairs. The Jaws of Life, a tool that has saved many lives in auto accidents, relies on a hydraulic power unit for its incredible cutting power. Farmers use hydraulic-driven machinery to tend and harvest their crops. The garbage truck that picks up your trash uses a hydraulic power unit to compact the garbage it collects. Your favorite amusement park ride probably utilizes hydraulics to lift you high and fast into the air and give you a soft, safe landing. Remember when you stepped on the brakes to avoid that last small animal that ran out into the road? Modern auto braking systems rely on the power of hydraulics.

 

It’s easy to overlook the widespread and impressive utility of hydraulic power pack units, but listing all of their applications it becomes clear that we rely on them for so much of what makes our society run smoothly and efficiently.
