A sealing element seals a space between a first bearing ring and a second bearing ring. The sealing ring includes a sealing disk which has a plurality of sealing segments on at least one periphery. Alternate sealing segments are oriented at positive and negative angles with respect to a main plane of the sealing disk. The sealing element is installed into the bearing such that the sealing segments extend into and contact a recess in one of the bearing rings.

Sealing element and bearing arrangement therewith

A bearing (), more particularly a radial anti-friction bearing, including a bearing ring () with a lateral surface () formed by at least one undercut (), and at least one sealing element () having an elastomer portion () and an elastic retaining lip (), wherein the elastomer portion of the sealing element is received in the undercut at least in some portions, wherein the lateral surface of the undercut has a contour () with a contact portion () for axially securing the elastic retaining lip, as well as an axial contact surface (), on which an axial contact surface () of the elastomer portion of the sealing element lies flat, is provided.

Bearing

A two-part bearing cage for a ball bearing, including a first and a second annular body () having a plurality of retaining claws () on their opposing end faces. The two annular bodies () have an identical design and can be mounted opposite each other in such a way that cut-out sections () receive the retaining claws (), thereby forming pockets () for receiving and guiding rolling bodies (). The number of pockets () corresponds to the number of rolling bodies (). According to the invention, the individual pockets () are arranged at a distance from one another in the circumferential direction in such a way that a free area () for receiving lubricant is formed between two pockets (). At least two pairs of retaining claws (), at least two individual retaining claws (), and the base of a pocket combine to form one pocket (). The invention also relates to a ball bearing comprising a two-part bearing cage of this type.

Two-part bearing cage comprising multiple lugs which form retaining claws, project outwards from two annular bodies into the interior and form free areas for lubricant, and ball bearing comprising a bearing cage of this type
