Importance of bearings

 Bearings play a crucial role in numerous industries by enabling the smooth operation of machinery and equipment. Functioning as mechanical components that facilitate relative motion between different parts, bearings help reduce friction and support loads, ensuring optimal performance and longevity of various mechanisms.

Their importance in industries cannot be overstated, as they are an essential element for smooth and reliable operation in a wide range of applications. To maintain the optimal performance of bearings, the use of suitable bearing lubricants is crucial.

The importance of a bearing lubricant

A bearing lubricant is of utmost importance in ensuring the reliable and efficient operation of bearings.

It serves as a vital protective barrier, reducing friction, dissipating heat, and maintaining the overall performance and integrity of the machinery. 

Choosing the right lubricant and adhering to regular maintenance practices are crucial for maximizing bearing performance and minimizing risks, making bearing lubrication an indispensable element in industrial operations.

Various types of bearing lubricants

Grease Grease is a semi-solid lubricant consisting of a base oil, thickeners, and additives. It has a higher viscosity compared to oil, which allows it to stay in place and provide long-lasting lubrication. Grease is often used in applications where continuous re-lubrication is not practical or feasible. It provides good sealing properties, protects against contaminants, and offers excellent load-carrying capabilities.
Oil Oil lubricants are liquid lubricants with various viscosity levels. They can be mineral-based, synthetic, or a blend of both. Oil lubrication allows for efficient heat dissipation and provides low starting torque. It is commonly used in high-speed applications where oil circulation systems or oil bath lubrication methods are employed. Oil lubrication offers excellent cooling properties and can be tailored to specific application requirements by selecting the appropriate viscosity grade and additives.
Dry Lubrication Solid lubricants, such as graphite, molybdenum disulfide (MoS2), polytetrafluoroethylene (PTFE), or tungsten disulfide (WS2) are dry lubricants that work by creating a thin film on the bearing surfaces. These lubricants have a low coefficient of friction and are often used in applications with extreme temperatures, high loads, or in environments where liquid lubricants may not be suitable.

The selection of the appropriate lubricant type depends on various factors, including the bearing type, operating conditions (such as speed, temperature, and load) and environmental factors.

Sliding Wear

Sliding wear occurs when two surfaces slide against one another causing material loss to one or both surfaces. Over time, this can result in component failures, additional maintenance, and costly down time.  

Coating components with Dicronite® can help minimize this wear and reduce the need for maintenance and down time.

Tight Tolerance Lubrication

Extremely tight tolerances can present challenges when lubricants or coatings are needed to reduce friction. Many products are available to help reduce friction, but in the case of very tight tolerances, few can be integrated without the need for adjustments.

Dicronite® has an average thickness of 0.5 microns (0.00002 inch) or less. This precision thin film allows users to incorporate Dicronite® on designs with tight tolerances without the need for design or manufacturing changes.

Vacuum Environment Lubrication

Vacuum environments present a challenge for lubrication. Many conventional lubricants aren’t effective under vacuum and are largely vaporized.

Dicronite® can be used in vacuum to reduce friction where other lubricants can’t function. The outgassing of Dicronite® under vacuum conditions is well below screening levels for spacecraft materials per ASTM E595.

Energy Lost to Friction

Friction is wasted energy! Systems with critical mechanical power output need to be extremely efficient.

Dicronite® optimizes mechanical efficiency by reducing friction losses and can even work in tandem with existing lubrication to further optimize efficiency.

Dicronite® is especially useful in precision systems, extreme environments, or where minimizing size and weight is vital.

Fretting is a unique form of sliding wear that occurs when contact surfaces oscillate over a very small range of motion. Although it may seem minor, this surface wear can ultimately lead to fatigue cracking and devastating damage.

Dicronite® helps remedy fretting by providing lubrication at contact surfaces. This effectively reduces the wear and surface stresses that cause so much damage.

Dicronite® can be integrated into existing designs and assemblies without any other adjustments for seamless reduction of fretting wear.

Extreme Temperature Lubrication

Extreme low or high temperatures can be challenging environments for lubrication. At low temperatures, conventional lubricants may be too viscous to be effective, while extreme high temperatures can result in breakdown of the lubricant.

Dicronite can be used in extreme environments to ensure effective lubrication while also being used in combination with oils and greases.

Dicronite is stable across a wide temperature range:

Excessive Heat from Friction

As friction in an assembly generates heat, elevated temperatures can result in unwanted operating conditions.

This can cause overheating and accelerate the breakdown of materials, resulting in costly maintenance and down time or destructive failure.

Proper lubrication can help minimize friction, reduce heat, and increase mechanical efficiency. Coat parts with Dicronite® to avoid excessive maintenance and ensure components will run as efficiently as possible.
