Choosing the Right Grease for Your Bearings

 

With every machine, comes maintenance. Some machines are high-end maintenance that requires dealing with them almost every day. Some are low-end that doesn’t require maintenance for at least a year. Regardless of whether your machine can survive without regular checkups, it is important to take care of its components inside.

Bearings are present in every machine. From hard drives to large vehicles, they all come in different shapes and sizes. They prevent heat from generating inside due to the friction that’s happening between the components. Despite being small, they also require maintenance in order to function properly. Maintenance instead of replacing them will save you a lot of money in the long run.


Importance of Bearing Lubrication

With properly maintained bearings, this will allow the machine to function more smoothly. The bearings will be able to fulfil their roles in the machine because they are properly maintained and well taken care of. There are three types of bearing lubricants: oil, grease, and dry film lubricants. Oil and grease are usually used for lubricating bearings.

How to Select the Right Kind of Grease Lubricant

There are three things to consider when choosing a lubricant for your bearings: base oil viscosity, base oil type, and the thickener type. There are also other factors to consider like the temperature in relation to the bearings and the speed for the bearings to function.

Grease is better to use than oil because it can be pre-lubricated and requires less maintenance. It also has less sealing requirements than oil. Before you choose grease as your primary lubricant, make sure to know its application procedures and operating conditions that the grease will play.

Base Oil Viscosity

The base oil viscosity of grease is often overlooked and misunderstood. The grease’s base oil viscosity should have the speed and dimensions of the bearings in mind when they function. The best base oil viscosity for grease is around ISO 460 or even higher.

Base Oil Type

The base oil type conditions for grease depends on how will it perform. Certain factors like temperatures, load, and pressure may affect the oil type conditions. Not only will the base oil get affected but also the additional package on it such as anti-wear etc. Synthetic oils can be used because they can cover a wide range of temperatures and conditions that may affect the bearings’ performance.

Thickener

What makes a good thickener type is that they abide with the standard recommendations of manufacturers. A good thickener must be able to withstand a lot of conditions the bearings will perform. It should be strong enough to keep the lubricant in place. Keep in mind to not perform a mix and match to lubricants or else it will cause potential damage to the bearing due to incompatibility.
