Synthetic High-Temperature Bearing Grease

Synthetic Bearing Grease Advantages

All components used in the production of Corfin Pe 416 grease allow it to operate over a wide temperature range and provide continuous lubrication. The high viscosity of the base oil provides excellent protection even under extreme loads.

WHAT IS SYNTHETIC BEARING GREASE?
Synthetic bearing grease has traditionally been the most widely used lubricant for rotating machine components such as bearings. It is mainly composed of a lubricant and a thickener. The thickener acts as a carrier for the lubricating component, holding the lubricant between the lattice-like fibers.

During the operation of machines, temperatures gradually increase and as a result, oil leaks from the grease and lubricates the surfaces inside the bearings. Traditional petroleum-based and synthetic greases use thickeners made from metallic substances such as lithium or calcium. The main reason they are formulated with additives is to meet extreme pressures, extreme vibration or any other demanding requirements.

The difference between conventional synthetic grease and Corfin Pe 416 synthetic bearing grease can be found in the quality of the lubricants. Conventional greases use petroleum-based products such as mineral oil. Corfin brand grease is formulated using synthetic hydrocarbon base oil and polyurea thickeners. As a result, they can withstand extreme temperatures and maintain lubrication effectiveness better than conventional greases.

Synthetic Bearing Grease Frequently Asked Questions

Synthetic greases consist of a thickener dispersed in the lubricant, such as petroleum oil or a synthetic liquid. The thickener may be soap, an inorganic gel or an organic substance. Other additives inhibit corrosion and oxidation, prevent wear, and modify viscosity. For gaps between relatively large parts, the liquid component is the more important lubricant, but for small gaps, layers of molecular soap provide lubrication. Synthetic grease may consist of synthetic oils containing standard soaps, or it may be a blend of synthetic thickeners or bases in petroleum oils. Generally, both the base and the oil are synthetic greases. Synthetic greases are manufactured in water-soluble and water-resistant forms and can be used over a wide temperature range. Synthetic greases can be used in contact with natural or other rubbers as they will not soften these materials.

Traditionally, grease has been the most common lubricant for rotating machine components such as bearings. It consists mainly of a thickener and a lubricant. The thickener acts as a carrier for the lubricating component, holding the lubricant between its lattice-like fibers. As the temperature rises during operation, oil is released from the grease and lubricates the contact and sliding surfaces of the bearings. Conventional petroleum-based and synthetic greases use thickeners made from a metallic substance such as lithium or calcium. They can be specially formulated with additives to meet extreme vibration, extreme pressure or other demanding requirements. The difference between conventional and synthetic greases is in the lubricant. Conventional greases use a petroleum-based product such as mineral oil. Synthetic greases use a synthetic lubricant such as silicone. As a result, they have a high resistance to extreme temperatures and can maintain lubrication efficiency much better than conventional greases.

Recently, synthetic greases have found increased use in rotating equipment. Long considered the lubricant of choice for applications involving extreme heat, loads and speeds, synthetic greases are becoming a more viable option for bearings and other components that face moderate operating demands. There are two main reasons for the growing popularity of synthetics. The first is the availability of new products and formulations. Synthetic greases are now available in additional viscosities and consistencies, and there are even “green” or biodegradable varieties. The increased choice allows maintenance and lubrication professionals to evaluate synthetic greases for a wider range of applications. The second is affordability. The cost of synthetic greases has not risen as fast as that of conventional petroleum-based greases, narrowing the cost gap between the two grease categories. As a result, synthetics are now a more affordable option in some applications where their use was previously cost prohibitive.

While conventional, mineral oil-based greases can be formulated to provide effective performance for many applications, synthetics typically provide some significant advantages, including longer oil life. Synthetic fluids provide superior lubricity over a much wider range of application temperatures, all else being equal. This is as true for lubricating oils as it is for greases. In high temperature applications, synthetic oil thins less than comparable mineral oils and provides greater protection by forming a thicker oil film between surfaces. In addition, these oils are less prone to degradation at high temperatures. In this sense, synthetic-based greases can provide stronger protection than standard greases.
