According to SKF, its new DryLube Bearings eliminate the need for grease re-lubrication and perform virtually maintenance-free over a wide temperature range.
That includes hostile and extreme-temperature applications found in metal and steelmaking and food and beverage operations, among others. Based on graphite or molybdenum disulfide and a resin binder, the problem-solving 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.
DryLube Bearings provide effective lubrication for extreme temperature applications up to 660 F (350 C), achieve higher speed capabilities than standard graphite-cage counterparts and exhibit minimal lubricant loss over time. They enhance worker safety by reducing fire risks and eliminating slippery surfaces and help contribute to “green” operating objectives compared with the use of of many oils and greases.
