Spherical Roller Bearings

Solid Oil lubricated SKF bearings are designed for use in applications where high humidity or contact with water and environmental contaminants pose challenges to bearing durability. These factors, along with inadequate lubrication, contribute significantly to premature bearing failures, which can be prevented through Solid Oil lubrication. The Solid Oil lubrication method is based on adding lubricating oil in solid form directly into the bearing. Bearings containing Solid Oil are lubricated for their entire lifespan, eliminating the need for re-lubrication during their operational life.

Solid Oil is a solid polymer matrix saturated with lubricating oil, fully filling the free space within the bearing and covering the cage and rolling elements. This design prevents moisture or contaminants from entering the bearing, and the lubricant cannot leak out of the bearing, even during washing. The polymer matrix serves as an oil reservoir, supplying oil to the rolling surfaces of the bearing in the required amounts during use, ensuring effective and optimal lubrication for the entirety of its lifespan.

The Solid Oil lubrication solution is available for the most common ball and roller bearings, as well as bearing units. Solid Oil can be identified by the W64 suffix in the bearing marking. Solid Oil is also available in food-grade versions.

Features and benefits:
- Maintenance-free bearing solution saves maintenance costs.
- Ensures a longer service life and replacement interval for the bearing.
- Helps avoid unplanned production downtimes.
- A significant amount of lubricating oil is retained within the bearing, extending the lubricant's lifespan.
- Wash-resistant, does not mix with water.
- Prevents lubricant leakage.
