How To Choose Ball Bearing Lubricant

graphiteBall bearing lubrication is one important aspect of increasing your bearings lifespan, but how do you know how to choose the right lubrication for your bearing? Meanwhile, this article discusses in detail the way to bring out the best in your bearings. Read on to discover all it entails.

Types Of Lubricant

Generally, there are two types of lubricant namely:

• Oil Lubricant
• Grease Lubricant

Oil Lubricant: Is a type of lubrication that makes use of thick fatty oil to make the parts of a machine move smoothly. The aim is to allow your bearings to withstand high load or high temperature and minimize friction.

Grease Lubricant: This is a type of lubrication that has a mixture of oil and thickener, it uses additives to reduce friction and premature wear between two moving parts in a mechanical component.

Importance Of Ball Bearing Lubrication

You cannot underestimate the importance of ball bearing lubrication because it’s the surest way to reduce friction between your bearing’s rolling elements, and it minimizes premature wear and tear. It fritter away the heats generated while on motion, prevent bearings from corrosion and contaminants, and extends bearings life.

Advantages Of Ball Bearing Lubrication

• Reduce friction and premature wear
• Reduce noise and vibration
• Prevents corrosion and contaminants
• Dissipates heat
• Long lifespan
• Creates a barrier between rolling elements and sliding surface
• Provides heat transference

Methods Of Ball Bearing Lubrication

There are diverse types of bearings lubricants, but knowing the one that works best for your type of bearings is important. Although, here are some types of bearing lubrication:

Mineral Oil Lubrication: This type of lubrication is the most common type in ball bearing lubrication. Mineral oil lubricants are affordable, good for reducing friction, made from crude oil, and they are available world-wide.

Grease Lubrication: Lithium, calcium, or aluminum are mixed together to form grease lubrication. The thickening agents (Lithium, calcium, or aluminum) helps to preserve the oil and guard the bearings from contaminants and corrosion. In addition, it performs well in different temperatures.

Dry Lubrication: Molybdenum disulfide or graphite are the dry lubricants that are used as an alternative where grease and oil lubrication fails to work. Dry lubrication is like a powder that is applied in between two moving parts, with the aim of reducing friction.

Synthetic Oil Lubrication: These types of lubrication give maximum performance more than oil lubrication, they are made from synthesized chemicals, and they have higher viscosity index i.e they are capable of withstanding all kinds of temperature.

Factors To Consider Before Lubricating Ball Bearing

Here are some factors to consider for longevity and best performance of your bearings as choosing the right lubricant for a particular situation is important.

Bearing Size And Shape: As you know that bearings types and sizes have various lubrication requirements, choosing the lubrication that aligns with your bearing size and shape should be a priority.

Speed: The requirement of lubricating high-speed bearings differ from that of low-speed bearing, so choose based on speed.

Load: Use lubricants that feature high viscosity if your bearings are operating on heavy loads to suppress the pressure.

Temperature: Use lubricants with higher thermal stability if your bearings are operating on higher temperature because higher temperature can affect the lubricant viscosity.

Environment: Your bearings operating in an environment where there is moisture, dust, and contaminants should also dictate the kind of lubrication you need.

Compactibility Of The Lubricant: Choose lubricant that is compatible with your bearing materials.

Lubrication Method: Make sure that automatic feeders, manual lubrication, and sealed-for-life bearings are recommended and good for your application.

Application Specifics: Start-stop cycles, oscillation, and vibration are some of the demands that should influence your lubrication needs.

Which Lubrication Method Is Suitable For Which Situation

Oil Lubrication Is Suitable For The Following:

• High-speed application
• High-temperature operations
• Application with specific lubrication needs
• Centralized lubrication system

Grease Lubrication Is Suitable For The Following:

• Sealed or shielded bearing
• Low and moderate speed application
• Sloped application and vertical shaft
• Simpler maintenance
• Harsh environment

FAQ

What Are The Parameters For Choosing A Proper Lubricant?

Parameters like vibration, dust, speed, moisture, temperature, and load are the important parameters that should influence your choice of lubricants.

Conclusion

In conclusion, although choosing the ball bearings lubricant might seem straightforward to you, it is important that you know that considering the factors that align with the unique features of your bearing are paramount.
