A roller bearing includes an inner ring and an outer ring and a cage between the inner ring and the outer ring in which a plurality of rollers are retained. The inner ring or the outer ring includes a guide flange for guiding the rollers, and a biasing member exerts a biasing force, directed toward the guide flange, on the rollers and/or on the cage.

Roller bearing

A preloaded bearing assembly includes two tapered roller bearings that each have an inner ring and an outer ring and rolling elements therebetween, wherein both bearings are preloadable with a predetermined preload force by relatively shifting the inner rings and/or the outer rings in an axial direction. Flanges are disposed on the inner rings and/or the outer rings and form an axial stop for the rolling elements, and at least one of the flanges is adjustable on or relative to the associated bearing ring in the axial direction. The axially adjustable flange is disposed with a predetermined press-fit on or relative to the bearing ring and is shiftable on or relative to the bearing ring against a frictional force provided by the predetermined press-fit, and the predetermined preload force is determined by a magnitude of the frictional force of the predetermined press-fit.

Bearing assembly with preload

A universal joint includes a bush, a bearing journal supported in the bush by a bearing and a seal assembly configured to form a seal between the bearing journal and the bush. The seal assembly includes an outer body formed from a first material having a first hardness, and a reinforcing body at least partially embedded in the outer body is formed from a second material having a hardness greater than the hardness of the first material. The reinforcing body contacts and forms a slip surface for a rolling element of the bearing. The reinforcing body and the outer body are configured such that the reinforcing body compresses a portion of the outer body against the journal when the seal assembly is mounted on the bearing journal.

Universal joint including a seal, seal, and method for installing a seal

A motor vehicle wheel bearing assembly includes a hub configured to be supported by at least one rolling-element bearing and to provide a seat for a wheel. The hub includes a first hollow-cone-shaped element manufactured from light metal and having a first axial end section having a first diameter and a second axial end section having a second, larger, diameter and at least one bearing raceway or raceway support at the first axial end section. The hub also includes a second element extending radially from an end of the first hollow-cone-shaped element, the second element having a radially inner section and a radially outer section.
