A sealed sleeve fan bearing consists of a stationary cylindrical body (sleeve) separated from a rotating shaft by a layer of lubricant. Sealed sleeve bearings are essentially standard sleeve bearings with an oil collection cup that catches the lubricant as it exits the bearing and recirculates it back into the fan thereby extending the fan life. This solution is slightly more expensive than a standard sleeve and yet, less expensive than a ball bearing and has a life expectancy somewhere between the two.
