Grease

The key distinction between lubricating oil and lubricating grease lies in the inclusion of soap (thickener) in grease. Grease possesses superior mechanical stability, high drop point, high load-carrying capacity, reduced wear, and excellent water resistance and corrosion protection properties.

Advantages of lubricating grease include:

• No need for complex sealing components and oil circulation systems, allowing for simplification of bearing size and overall equipment, enabling smaller and more streamlined designs.
• Grease exhibits a long-lasting effect, requiring less frequent replenishment, particularly beneficial for friction components that are difficult to maintain.
• Good adhesion and sealing properties enable grease to function in open and poorly sealed components, preventing the ingress of water and dust.
• Grease forms a thicker oil film than lubricating oil, providing enhanced protection to metal surfaces. Grease also has a broader temperature usage range compared to lubricating oil.

Potential disadvantages of lubricating grease are:

• Grease is a semi-fluid substance and can be less flowable at room temperature. This makes changing grease on components more challenging, and bearing cleaning can be cumbersome, often requiring partial or complete disassembly.
• Incorporated water, dust, and debris are difficult to remove from grease. In contrast, impurities in lubricating oil tend to rise or settle, making their removal through drain holes or skimming relatively easy.
• Greater resistance can lead to poorer heat dissipation and cooling capabilities.
• The suitability of grease or oil depends on the equipment’s condition and the specific lubrication points.

There is no absolute good or bad; it’s a matter of whether the lubricant is appropriate for the intended application. If you’re unsure about the situation, feel free to contact our technical service for assistance.
