A cage segment for a rolling-element bearing having a plurality of rolling elements includes at least one bridge and first and second plates extending from axial ends of the bridge, sides of the bridge being configured to guide rolling elements. Radially inner or outer edges of each of the bridges include at least one axial channel having channel walls projecting radially and circumferentially from the radial inner or outer edge.

Bearing cage segment configured for use with an installation tool

A method for assembling a tapered roller bearing includes providing a first rolled-on surface element having a raceway and an axial end surface and mounting a plurality of tapered rollers separated by a plurality of bearing cage segments or by a plurality of roller spacers on the raceway, where each of the plurality of tapered rollers has a frustoconical rolling surface and a circular end surface meeting at a junction. Also placing at least one assembly ring around the plurality of tapered rollers to hold the plurality of tapered rollers against the first rolled-on surface element, and moving a second rolled-on surface element coaxially toward the first rolled-on surface element such that a portion of the second rolled-on surface element contacts the at least one assembly ring and pushes the at least one assembly ring axially off the plurality of tapered rollers.

Method for assembling a tapered roller bearing, and assembly unit for this purpose

An assembly tool for a bearing ring having roller members, the tool including a ring configured to be arranged on a side face of the bearing ring and including sliding elements received in receiving members on the ring. The sliding elements are distributed peripherally in a uniform manner around the ring and are configured to be displaced from a starting position into an end position relative to the ring. When the tool is mounted on the ring, the sliding elements, positioned in their end positions, extend between adjacent roller members and limit a radial movability of the roller members relative to the bearing ring.

Assembly tool and method for mounting a bearing

An installation tool for a bearing ring including rolling elements includes a ring that is configured to be disposed on a lateral surface of the bearing ring and slider elements extending through receptacles in the ring. The slider elements are uniformly distributed circumferentially around the ring and are displaceable relative to the ring from an initial position into an end position and are configured to be disposed in the end position between two rolling elements and against a contact surface of a wall of a cage segment, which wall is disposed between two rolling elements, in order to limit axial and radial movement of the rolling elements relative to the bearing ring.

Installation tool

A bearing ring for a rolling-element bearing includes a rolling-element raceway that is axially delimited by a guide flange and a retaining flange. At least the retaining flange is configured as a separate element that is fixedly connectable to the bearing ring, and the bearing ring includes a substantially radially extending stop that is offset inward from an axial end of the bearing towards the raceway.

Bearing ring for rolling-element bearing

A roller bearing seal includes an insert part and a polymer part connected to the insert part, and the insert part includes an annular-disc-shaped middle section having a radially inner deflection and a radially outer deflection, and a first ratio (L/L) of an axial length (L) of the outer deflection to an axial length (L) of the inner deflection is less than 0.65.

Seal and roller bearing

A bearing ring for a roller bearing includes a raceway configured to support at least one rolling-element roller and a flange at an end of the raceway extending away from the raceway and having an abutment surface for guiding the at least one rolling-element roller on the raceway. The abutment surface has a curvature that decreases monotonically from a starting point on the abutment surface to an end of the abutment surface, and the abutment surface includes at least one strongly monotonically decreasing segment.

Roller bearing flange configuration

A tapered roller for a tapered roller bearing, the tapered roller bearing having a raceway and a flange, and the tapered roller having a rolling surface configured to roll on the raceway and an end surface at the end of the rolling surface configured to face the flange. The end surface includes an abutment surface having a curvature and a radially outer end and a radially inner end and is configured to contact the flange. The curvature increases monotonically from a starting point on the abutment surface to the radially inner end of the abutment surface.

Configuration for a roller of a roller bearing

A bearing ring for a roller bearing includes a raceway for at least one roller that includes an at least partially spherically formed roller end surface having a first curvature. A flange for transferring axial forces extends from an end of the raceway and has a flange surface that faces towards the roller end surface. A spherical flange surface section having a second curvature is defined on the flange surface. The first curvature differs from the second curvature such that a first gap (d) exists between the spherically formed roller end surface and the spherical flange surface section. The flange surface also includes an opening flange surface section having a third curvature, which is less than the second curvature, such that a second gap (d) exists between the roller end side and the opening flange surface section. The second gap is larger than the first gap.

Geometric concept for a roller-flange contact in roller bearings

A roller bearing assembly includes at least one roller bearing having an outer ring, an inner ring, and roller bodies disposed therebetween, as well as a radial shaft seal ring having a support ring and a seal lip. At least one end side of the outer ring includes a receptacle for retaining the support ring. The support ring extends axially in an outwardly projecting manner beyond the end side of the outer ring and up to an outer circumferential surface of the inner ring. The seal lip connected with the support ring sealingly abuts on the outer circumferential surface of the inner ring at a position that is axially internal of the end side of the outer ring.
