Bearings are the most common part in any mechanic devices. However, they need to be maintained or lubricated to keep fast rotation speed and prevent bearing frictions.
How do we lubricate a bearing?
As we all know lubricant can be liquid or solid. Choosing proper lubricant is essential for keeping a proper running and long service life for a bearing. Lubricant has the following functions:
- facilitates movement
- avoids wear and premature fatigue
- reduces internal friction
- ensures that the bearings are sealed against external bodies
- reduces the operating noise
- protects the bearing against corrosion
You may have two choices to choose oil or grease as lubricant. What are differences between these two kinds of lubricant?
Generally speaking, grease lubrication is definitely the simplest and most efficient choice because it provides all the functions mentioned above and also allows for operation with low maintenance. However, if your bearing is integrated in an oil-lubricated machine, we recommend that you use the same lubricant system. In any case, the choice of lubricant will depend on three factors: the load, the type of operation (continuous or intermittent), and the speed of rotation.
If the bearing is subject to high loads, the operation is continuous and the rotational speed high, then oil lubricant is the ideal solution to ensure the proper functioning of your rolling system. On the other hand, if the loads are low and the speed limited then grease will be more than sufficient.
