Solid Lubrication: Revolutionizing Bearing Applications for Unparalleled Reliability

In the world of industrial applications, bearing lubrication plays a pivotal role in ensuring optimal performance and prolonging the life of critical components. However, traditional grease lubrication has proven to be a major cause of premature bearing failure due to its complex and challenging nature. 

Fortunately, a revolutionary solution in the form of solid lubrication has emerged, offering unparalleled benefits that can change the way we perceive the lubrication process. In this blog, we will explore what solid lubrication is, its advantages for bearing applications, and how it surpasses grease in terms of effectiveness.

The Problem with Grease:

Grease lubrication poses numerous challenges, such as the need to calculate the right amount and frequency of relubrication for each bearing application. When multiple bearings are involved, with varying speeds and loads, determining appropriate lubrication intervals becomes a complicated task.

Additionally, achieving the ideal fill quantity for bearings remains uncertain, potentially leading to under- or over-lubrication, which both can be detrimental. Moreover, grease is susceptible to contaminants, either through direct introduction during lubrication or through compromised seals, resulting in costly bearing failures.

A Higher Level of Protection with Solid Lubrication:

Solid lubrication (SL) introduces a game-changing approach to bearing lubrication. Unlike grease, SL eliminates the need for complex lubrication calculations and intervals. Each bearing is pre-filled with a polymer that contains up to four times more oil than a greased bearing. This ensures a constant and on-demand release of lubricant as the bearing operates. When at rest, the polymer reabsorbs the oil, maintaining simplicity and reliability.

Protection against Contamination:

Contamination is a significant concern in bearing applications, particularly in industries with harsh environmental conditions. Greased bearings, when contaminated, suffer damage to their metal components, leading to premature failure. 

In contrast, solid lubrication prevents the ingress of contaminants as the oil is impregnated within the polymer, making it practically immune to contamination. The solid nature of the polymer additionally enhances protection against liquid infiltration, a challenge that grease faces.

How Solid Oil Improves Bearing Reliability:

Bearings equipped with solid lubrication demonstrate unparalleled reliability even in the dirtiest and wettest environments. Frequent washdowns, which can harm grease-lubricated bearings through emulsification or wash-out, pose no threat to SL-equipped bearings. 

The polymer filling reinforces seals, preventing deformations and sealing failures that could allow contaminants to enter the bearing. This enhanced protection, along with exceptional oil retention, extends bearing life and reduces the frequency of washdowns, minimizing downtime and increasing productivity.

Closed to Contamination in Dirty Industries:

Industries like agriculture face constant challenges due to the presence of dirt and debris, which significantly reduce bearing life. Solid lubrication proves especially effective in these demanding applications. 

The secondary sealing capability of the polymer ensures that bearing internals remain shielded from contaminants, eliminating the need for frequent maintenance and enabling seamless production with reduced downtime.

Eliminating the Need for Bearing Maintenance:

Greased bearings necessitate regular and ongoing maintenance. Errors in maintenance contribute to nearly 80% of premature bearing failures. With solid lubrication, bearings come from the factory properly lubricated for their entire service life. By replacing greased bearings with SL-equipped ones, the human element in maintenance is eliminated, reducing the risk of over and under lubrication.

Solid lubrication is a transformative innovation that offers improved reliability, reduced long-term costs, and extended uptime for bearings across various industries. 

By eliminating the complications of grease lubrication, solid lubrication paves the way for continuous reliability and efficient operations. Thus enhancing the performance of critical components and revolutionizing the way we approach bearing lubrication. 

As industries embrace this revolutionary technology, they can expect enhanced productivity, reduced downtime, and a competitive edge in the market.
