Öljyrasvavoitelu

Öljyrasvavoitelu, also known as oil-grease lubrication, is a lubrication method that combines the properties of lubricating oils and greases. This technique is employed in applications where a single lubricant might not provide optimal performance. The principle involves using a grease as a carrier for oil, or sometimes using a mixture of oil and grease.

In some applications, a standard grease is used, but it is overpacked or designed to bleed oil over time, which then serves as the primary lubricant. This allows for the long-lasting nature of grease combined with the fluid lubrication of oil. Another approach involves creating a specific blend of oil and grease components to achieve a desired consistency and lubrication profile. This can be particularly useful in situations with varying temperatures or load conditions.

The benefits of öljyrasvavoitelu include improved wear protection, better sealing capabilities, and extended lubrication intervals compared to using oil or grease alone. It can be advantageous in machinery operating under heavy loads or in environments where maintaining a consistent oil film is challenging. However, it is important to select the correct oil-grease combination to avoid issues such as oil separation or incompatibility between components. The specific formulation and application method depend heavily on the machinery and its operating environment.
