SKF DryLube Bearings are filled with a dry lubricant based on graphite or molybdenum disulfide and a resin binder. The dry lubricant is injected into the free space of the bearing, bonded to the cage, and cured until it solidifies.
SKF DryLube Bearings eliminate any need for grease relubrication, according to the developers, and are designed to perform reliably and virtually maintenance-free over a wide temperature range. These high-temperature bearings are particularly suited to hostile and/or extreme temperature applications.
SKF develops and supplies bearings, seals, mechatronics, and lubrication systems, and supplies technical support, maintenance and reliability services, engineering consulting and training.
SKF DryLube Bearings are filled with a dry lubricant based on graphite or molybdenum disulfide and a resin binder. The dry lubricant is injected into the free space of the bearing, bonded to the cage, and cured until it solidifies. During the bearing’s operation, the dry lubricant maintains a thin film on the bearing’s raceways and rolling elements to protect against metal-to-metal contact and any potential damage caused by solid contaminants.
The bearings can provide effective lubrication for extreme temperature applications up to 350°C (660°F), achieve higher speed capabilities than standard graphite-cage counterparts, and exhibit minimal lubricant loss over time. In particular, they promote worker safety by reducing fire risks and eliminating slippery surfaces, and can additionally contribute to green operating objectives compared with many oils and greases.
SKF DryLube Bearings are available in four main variants to satisfy most operating conditions.
