FAG floating displacement bearing (FD) is the ideal floating bearing solution.The FD FAG bearing is composed of the outer ring of the ball bearing and the inner ring of the cylindrical roller bearing.This structure design ensures that the inner ring can float freely relative to the outer ring when the bearing is running, reaching the speed of the high-speed angular contact ball bearing, which is 2 times higher than the speed of the ordinary cylindrical roller bearing.

The steel ball of FAG's floating displacement bearing uses a ceramic ball as the standard rolling element, and the inner ring is manufactured from Cronidur30 high performance bearing steel, which has a higher permissible Hertz contact stress than ordinary bearing steel.The contact between the Cronidur30 steel and the ceramic ball ensures sufficient carrying capacity between the inner ring and the roller.FAG FD bearing with B70...Series angular contact ball bearings or N10...The cylindrical roller bearings of the series have the same external dimensions, their sufficient bearing capacity and high speed capability to provide designers with a new design of floating bearing configurations.FD bearings can be used in existing structures with lower rated load and can easily increase the allowable speed.

FAG provides floating displacement bearing spindle bearings with open and two side seals (2RSD) or direct lubrication type for oil/gas lubrication.Similar to FAG ultra-precision cylindrical roller bearings, FD bearings also have inner hole with taper (K) products.
