Why & How?

Lubrication is essential for the proper function of bearings because it reduces friction, which can cause damage or failure of the bearing. Lubrication also protects against corrosion and contaminants that can damage bearings and other wheel-end components. In the correct applications, lubricants extend the useful life of bearings to their optimum range.

​

For every industry, lubrication is vital to the performance of rotating equipment; when over 40% of maintenance cost are related to poor lubrication, proper management is crucial. The right quantity of the right lubricant applied at the right intervals is essential to achieving optimum application performance and maximum service life. 

​

Reduction of Friction

The primary role of lubrication is to reduce friction between bearing components and adjacent components such as the spindle or axle. The heat generated by friction can cause bearings to deteriorate in a number of ways, including the destruction of seals, balls or raceways, depending on the type of bearing in your vehicle or machinery. A lack of lubrication can cause excessive friction, leading to bearing failure and leaving a devastating outcome.

​

Prevention of Corrosion

Contaminants such as water, salt and organic debris can cause bearings to corrode and fail over time. Lubrication serves as a vital barrier of protection against these contaminants, keeping the integrity of bearing intact. If bearing seals become loose, punctured, or otherwise damaged by debris, seeping lubricant can allow contaminants into the bearing and cause failure. It is important to inspect bearings and seals regularly to prevent untimely corrosion-based failures.

​

Stabilization of Bearing Structures

Bearing lubricants can help bearings endure different loads and act as a stabilizing agent for bearing structures. The stabilizing effect of lubricants differs depending on whether grease, oil, or synthetic lubricants are used. You can count on bearing lubricants to help reinforce the overall functionality and reliability of bearings.

​

Lubrication is one of the most important factors impacting the operation and longevity of bearings, which is why it is important to inspect and monitor bearing function on a regular basis. Without effective lubrication, works are being setup for potential breakdowns.
