At the very heart of a dc fan—both literally and figuratively—is the bearing that enables the rotor to turn. A typical fan will need to make a significant number of rotations during its lifetime, so a lot gets asked of the bearing. It is, therefore, crucial that it is up to the task. Read this whitepaper to learn how CUI’s omniCOOL™ system bridges the cost-performance gap between traditional sleeve and ball fan bearings, thanks to the combination of its magnetic structure and enhanced sleeve bearing design.
