This solid lubricant with an oil-filled porous structure fills the space between the rolling elements and races in a bearing, providing constant and consistent lubrication. There is no need for additional lubrication during the life of an ARMOR filled bearing. Because it is a solid, ARMOR Bearings Permanent Lubrication can help block debris and reduce foreign contamination of the bearing. Reducing the incursion of debris into the bearing can significantly extend the bearing’s life. The solid structure of ARMOR also improves equipment maintenance, as it will not drip out of the bearing and contaminate the environment. Filling bearings with ARMOR solid lubricants does not alter the dimensional tolerances of the bearing. ARMOR solid lubricant simply fills the spaces between the rolling elements and the cage.
