Lubtect® is a lubricant compound essentially comprising a polymer and a lubricant. The compound fills the cavities in the rolling bearing and, after filling, forms a rigid, porous matrix structure.

This structure stores a larger quantity of lubricant than in a bearing with conventional grease lubrication. During operation, the lubricant reaches precisely those areas where it is required, namely the contact zones of the rolling elements. Under particular application conditions, rolling bearings filled with Lubtect® can offer advantages in terms of operating life and  security against failure compared with grease-lubricated rolling bearings.
