A bearing is designed to reduce friction between moving parts. Ball bearings do this by letting the parts roll on balls between the two parts, like wheels on a car letting the car roll forward without dragging on the ground. Sleeve bearings achieve the same thing by using a liquid between the two parts instead of solid balls — usually some kind of oil. This is like putting soap and water on a plastic sheet in the summer so you and your kids can slide down a hill.
Neither of these two examples apply to the Enlobal bearing, which uses a magnetic field in place of balls or oil. The Enlobal bearing is like a maglev train, in which the train is suspended on a magnetic cushion above the track, with only air between the two. Thus, friction between the moving parts is greatly reduced, since most of the time they are only in contact with the air, not each other. (That said, it is worth pointing out that at least one SPCR user has found that oiling the Enlobal bearing improved both vibration and noise dramatically).
