Abstract: The bearing includes a first ring, a second ring, at least one row of radial and axial rolling elements arranged between axial and radial raceways provided on the rings. The second ring has a protruding nose engaged into an annular groove of the first ring and provided with the axial raceway and with the radial raceway of the second ring. The bearing further provides at least one cage for maintaining the row of axial rolling elements and at least one flange for guiding and maintaining the cage in radial direction. The flange axially abuts against a flat surface of the second ring. The bearing further includes a plurality of fixing screws to secure the flange to the second ring, the fixing screws extending axially through the flange.

Abstract: A thrust bearing includes a first axial end washer defining thereon a first race, a second axial end washer defining thereon a second race, a one-piece, radially-inner washer having a first axial end engaged with the first axial end washer and having a second axial end defining thereon a third race, and a one-piece, radially-outer washer having a first axial end defining thereon a fourth race and having a second axial end engaged with the second axial end washer. A first set of tapered rolling elements is supported between the first race and the fourth race and a second set of tapered rolling elements is supported between the second race and the third race. The first and second sets of tapered rolling elements are both axially and radially offset from one another.

Abstract: An axial roller bearing includes a first bearing including a first cage and a first plurality of rollers and a second bearing including a second cage and a second plurality of rollers. The axial roller bearing further includes a first washer positioned on a side of the first bearing, a second washer positioned on a side of the second washer which is opposite from the side of the first bearing on which the first washer is positioned, and a connecting washer positioned between the first bearing and the second bearing. The first cage is attached at an inner side to the first washer and at an outer side to the connecting washer. The second cage is attached at an inner side to the connecting washer and at an outer side to the second washer.

Abstract: A transmission wheel arrangement includes a shaft and a transmission wheel having a hub and rotatably arranged on the shaft. An axial bearing and a radial bearing are arranged axially and radially respectively between the hub of the transmission wheel and the shaft.

Abstract: A fifth wheel coupling for connection of a semitrailer to a tractor unit is disclosed in which a pair of symmetrical, swivel-articulated closing jaws having semicircular recesses for grasping the king pin have a split bearing comprising an outer bearing half fixed in each closing jaw and inner bearing halves rotatable with respect to the outer bearing halves. The split bearing includes a mechanism for returning each inner bearing half to a position aligned with its respective outer bearing half for uncoupling. The split bearing eliminates friction between the king pin and the closing jaws and is substantially free from wear and maintenance.

Abstract: A composite cylindrical roller bearing assembly including an inner ring having an annular projection on its outer peripheral side, an outer ring having an annular recess to receive the annular projection on its inner peripheral side, upper and lower cylindrical thrust rollers held by upper and lower retainers and disposed in upper and lower spaces formed above and below the projection in the recess, cylindrical radial rollers held by a retainer and disposed in an annular space between peripheral surfaces of the recess and the projection, and an annular gear to be meshed with an external gear. The inner ring is divisibly composed of first, second and third annular inner ring sections each of which is divisibly composed of two generally semicircular parts. One of the above annular inner ring sections has projections defining teeth of the annular gear on its inner peripheral side.
