SKF DryLube Bearings eliminates need for grease relubrication while performing reliably and almost maintenance-free over a wide temperature range. These next-generation high-temperature bearings especially suit hostile and extreme-temperature applications.
SKF DryLube Bearings are filled with a dry lubricant based on graphite or molybdenum disulfide with 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 bearing operation, the dry lubricant maintains a thin film on the bearing’s raceways and rolling elements to protect against metal-to-metal contact and potential damage caused by solid contaminants.
The bearings can lubricate applications up to 350ºC (660ºF), achieve higher speed capabilities than standard graphite-cage counterparts, and exhibit minimal lubricant loss over time. They also improve worker safety by reducing fire risks, eliminating slippery surfaces, and contributing to “green” operating objectives when compared with many oils and greases.
