Abstract: A differential allowing relatively easy alignment and secure positioning of bearings is provided. The differential includes a differential carrier and a differential case disposed within the carrier. A bearing assembly is located between the differential carrier and the differential case and allows the differential case to rotate within the differential carrier.

Abstract: A needle roller bearing is proposed in which treating gas can infiltrate more easily into the bearing during carburizing/nitriding treatment to promote treatment inside the bearing. The needle rollers are prevented from coming out by an inward flange provided at one end of the outer shell and an outward flange provided at the other end of the inner shell, and an inwardly bent edge provided at the other end of the outer shell is superimposed on the outside of the outward flange of the inner shell to establish axial engagement between the outer shell and the inner shell. The diametric overlap amount between the outward flange of the inner shell and the bent edge of the outer shell is set to a minimum limit necessary to maintain engagement therebetween so that treating gas can infiltrate into the bearing through the gap at the overlap portion.

Abstract: An apparatus for retaining a bearing assembly on the neck of a roll in a rolling mill. The apparatus includes an adaptor element having outwardly projecting first lugs circumferentially separated by first flutes. Fasteners detachably secure the adaptor element to a distal end of the roll neck. A locking element, which comprises an integral component of the bearing assembly, has inwardly projecting second lugs circumferentially separated by second flutes. The locking element is rotatable between an unlocked position at which its second lugs are aligned with the first flutes of the adaptor element to accommodate axial shifting of the bearing assembly onto and off of the roll neck, and a locked position at which its second lugs are aligned with the first lugs of the adaptor element to axially retain the bearing assembly on the roll neck.

Abstract: A cylindrical roller bearing includes an outer bearing ring, an inner bearing ring and cylindrical rollers located between the outer and inner bearing rings. One of the rings has side rims forming an axial stop for the cylindrical rollers. The bearing ring on which the side rims are not provided is formed with at least one groove outside the axial extension of the cylindrical rollers. A ring of spring-elastic material is positioned in the groove to form an axial stop for the cylindrical rollers. The periphery of the ring has no interruptions. To improve the running behavior of the cylindrical roller bearing, the ring possesses a V-shaped cross-section with two legs.
