Abstract A BEARING FOR SUPPORTING A ROTATABLE SPINDLE IN A HOUSING INCLUDES A CONE ENCIRCLING THE SPINDLE, A CUP IN THE HOUSING, AND A PLURALITY OF TAPERED ROLLERS POSITIONED BETWEEN AND ENGAGED WITH THE CUP AND CONE. A FLOATING RIB RING BEARS AGAINST THE LARGE DIAMETER END FACES OF THE ROLLERS ADJACENT TO THE CUP, AND THIS RIB RING IS HOUSED IN A RIB RING CARRIER. CONNECTED WITH THE CARRIER IS RIB POSITIONING MEANS FOR MAINTAINING A SUBSTANTIALLY CONSTANT FORCE ON THE RIB RING SO THAT THE PRELOAD OF THE BEARING DOES NOT VARY FROM A SELECTED SET POINT AS THE BEARING AND THE SURROUNDING STRUCTURE EXPERIENCED DIFFERENTIAL THERMAL EXPANSION. THE POSITIONING MEANS MAY BE ADJUSTED TO ANOTHER SET POINT WHILE THE SPINDLE IS ROTATING IN WHICH CASE IT IMPARTS ANOTHER SUBSTANTIALLY CONSTANT FORCE TO THE RIB RING AND THAT FORCE CORRESPONDS TO THE NEW SET POINT.
