A seal arrangement () of an anti-friction bearing, which seal arrangement () is inserted between a first bearing part () and a second bearing part (). The seal arrangement includes a seal () which is positioned on the rotationally fixed first bearing part by a support element () which is enclosed at least on one side by an elastic seal material (), and which seal () includes at least one sealing lip (). A thrower ring (), forming a collection chamber (), of the seal arrangement is assigned to the second rotatable bearing part. To this end, a cylindrical portion () of the thrower ring is snapped in an end-side circumferential groove () by a flange () of the second rotatable bearing part. A radial leg () of the thrower ring extends such that it maintains a sealing gap () to the seat. Moreover, the seal of the seal arrangement includes elastic sealing lips which are supported on the second bearing part such that they are offset with respect to the thrower ring.

Seal arrangement having a thrower ring for an anti-friction bearing

A seal arrangement with a centrifugal ring for a sealing between a rotatable bearing part and a static bearing part. The centrifugal ring has a first end piece, which forms both an outer circumference of the centrifugal ring and a cutoff edge located on a disk-shaped outer face. The seal arrangement reduces the coefficient of friction without having to accept any loss of sealing effect, but in which the seal arrangement nevertheless remains cost-effective to manufacture. For this purpose, the centrifugal ring has a second end piece. The end pieces together form a first collecting channel in the vicinity of the cutoff edge and the end pieces each form an annular seal gap with a static bearing part.

Centrifugal ring with collecting channel

A steering knuckle, which is provided for receiving an outer ring of a wheel bearing, and a wheel bearing arrangement with such a steering knuckle. The sealing arrangements of the wheel bearing has a pre-seal, which is designed as a labyrinth seal to provide sealing for an appropriate gap geometry. To this end, the steering knuckle has a collecting channel, which captures liquids and dirt particles and discharges them at the periphery. The hearing seal can be changed by this measure, so that savings are possible with a minimum of sealing action of the conventional sealing arrangement and with greatly reduced friction torque. Overall, the sealing action, which is now achieved by the bearing seal and the pre-seal together, is increased or remains at least at the same level while manufacturing costs are reduced.

Steering knuckle with pre-sealing

The invention relates to a seal with non-contact adjacent deflector rings, arranged concentrically to each other, about a common rotation axis, whereby, on a first deflector ring of the deflector rings, at least two axially-adjacent radial lips are embodied an said radial lips are embodied such as not to come into contact with a second deflector ring of the deflector rings and an annular hollow cavity is embodied between two axially-adjacent radial lips and the second deflector ring.

Seal with non-contact adjacent deflector rings

A rolling bearing which has a sealing arrangement and a sensor component, particularly an encoder, which is fitted with a mounting flange. The rolling bearing further has an inner ring and an outer ring between which rolling members are arranged. The sealing arrangement is equipped with at least one sealing element between the inner ring and the outer ring. In order to provide a rolling bearing which can easily be retrofitted with a retrofit sensor, particularly a retrofit encoder, and is well protected against environmental influence, the sensor component that is fitted with the mounting flange is designed as a retrofit part, while at least one water discharge port is disposed in the region of the mounting flange.
