Self-Lubricating Bearings

The NSK Molded-Oil™ series bearings are pre-lubricated with a special oil-impregnated resin, making them particularly suitable for environments where lubrication is challenging, such as those contaminated by water and dust. This eco-friendly technology gradually releases oil from the Molded-Oil™ resin, minimizing oil leakage and ensuring consistent lubrication. Stainless steel versions are available for use in corrosive environments, and there are also variants designed for high-speed applications. The Molded-Oil™ technology can be applied to various types of bearings, including deep groove ball bearings, spherical roller bearings, and tapered roller bearings.

The maintenance-free C-Lube series bearings feature IKO's innovative lubrication technology, which consists of a thermosetting solid lubricant that fully envelops the needle rollers. As the bearing rotates, oil from the polyolefin resin is released through capillary action in minimal but enough, maintaining lubrication performance over an extended period. Key advantages of the C-Lube technology include suitability for applications where maintenance is difficult, eliminating the need for manual lubrication or centralized lubrication equipment, and preventing oil dispersion. This technology is available for needle roller bearings, cam followers, and roller followers.

Timken also offers compelling solutions with its Solid Lube bearings, a maintenance-free and cost-effective alternative to grease lubrication, even in the most demanding applications. Beyond the general-purpose version, Timken has developed specific polymer-based solutions for food applications (H1 class approval according to NSF standards) and high-temperature environments (up to +176°C). Additionally, the graphite-based solution addresses issues in applications characterized by extremely high temperatures (up to +232°C), while still complying with NSF's H1 class. These solid lubrication solutions are available for deep groove ball bearings, insert bearings, and spherical roller bearings.

SKF offers the Solid Oil technology for nearly all types of ball and roller bearings, providing specific solutions for high loads, extremely low temperatures (down to -54°C), and food industry applications.
