1. You shouldn’t use the same grease for all your machines and parts
It can be tempting to choose one grease for all your equipment. Although this may work in some cases, it can cause problems over time. If you want to prolong the useful life of your equipment, each grease should be tailored to your machine and the conditions on your job site.
Additionally, different parts of a machine could require different types of greases, depending on the operating temperature.
A lighter grease may be required if you have an automatic lubrication system.
2. Make sure to check the grease recommendations in your equipment handbook
Your machine’s operator manual is a good place to start when choosing the right grease. Even though not all manuals provide detailed advice on greasing, there will be a general suggestion. This is a good place for beginners.
3. Wet conditions require different grease
It may be a good idea for your machine to be exposed to water. Marine greases are made with lithium complex thickeners that can protect your machines from salt and prevent rust. We recommend that you use grease from a reliable lithium stearate distributor.
4. Consider the application of your equipment when deciding on the grease you will use.
It may be a good idea for grease to contain molybdenum disulfide (molly) if the job involves a lot of pressure on a machine. The additive aids the grease in getting into small machine bushings and pins. Welding can occur when parts aren’t sufficiently greased.
5. The season will match the grease
There are different viscosities or thicknesses to grease. Grease with the highest viscosity is good for summer use since it tends to thin during hot weather. Grease with a lower oil viscosity may perform well in winter.
Synthetic grease can be used for cold or heat, and it is resistant to extreme temperatures.
6. Use a different grease to withstand extreme pressure
Heavy equipment is often designed for extreme pressure operations. Some manufacturers recommend grease that contains a molybdenum disulfide (or “moly”) additive for these applications. The moly can get into the smallest machining marks on pins or bushings, and prevents them from coming in contact.
Different types of grease and when they should be used
All grease is made of a fluid lubricant. It can be mineral oil or synthetic oil. Others might contain additives. Here are four categories.
Moly grease – A high-quality, affordable grease. It is suitable for machines with moving joints such as a loader, backhoe, or other heavy-duty machinery.
Next Level Up
Polyurea, or (multipurpose), grease –This grease is suitable for parts that can reach high temperatures. A polyurea grease won’t melt as fast as other types of grease because it is not designed for machines that have spinning grooves or spindles.
Synthetic oil–This grease is more expensive than regular grease but lasts three times as long as petroleum-based grease.
Many types of grease can be used for specific gearboxes or applications. High-impact greases, such as those made for hammers, are designed to withstand the pounding. You need to make sure that you are using the correct grease tube. Specialty greases can be used for specific purposes. They are not recommended to be used for general purposes.
