A rolling-element bearing includes a first bearing ring, a second bearing ring, and a seal unit formed in a multiple-piece manner, the seal unit including an at least part-ring shaped main element which is freely rotatable with respect to the first bearing ring and the second bearing ring and at least one seal lip. In addition, the main element and the seal lip are exchangeably connectable to each other.

Rolling-element bearing including seal unit

A seal unit for a rolling-element bearing having an inner bearing ring and an outer bearing ring. The seal unit includes an at least part-ring shaped element having a seal lip, the at least part-ring shaped element is configured for attachment to the inner bearing ring, and the outer bearing ring is tiltable through a limited angle with respect to the inner bearing ring. Also a rolling-element bearing having such a seal unit.

A bearing having grease lubrication includes a first ring and a second ring. A plurality of screw holes axially extend through the first ring. A first axial end of the first ring is affixed to a housing by a plurality of screws extending from the housing into the respective screw holes. A first bore is defined in the first ring adjacent to a second axial end of the first ring. The first bore intersects and fluidly communicates with one of the screw holes such that grease is dischargeable therethrough.

A bearing assembly comprises a bearing enabling a rotatable body to rotate about a rotational axis relative to a stationary body. The bearing includes a bearing inner ring and a bearing outer ring, each having at least first and second roller body tracks provided in or on non-parallel surfaces of the ring. The respective roller body tracks of the bearing outer ring are aligned with the respective roller body tracks of the bearing inner ring and a row of roller bodies is disposed between each of the respective sets of roller body tracks. At least one of the rows of roller bodies comprises one of tapered rollers and spherical rollers, at least one of the rows of roller bodies supports at least axial forces and at least one of the rows of the roller bodies supports at least radial forces.

Bearing assembly

A bearing assembly comprises at least one bearing for rotatably supporting a support roller having at least one hollow cylindrical portion. A support element is disposed directly or indirectly between a ring of the at least one bearing and the support roller. The support element comprises first and second hollow-cylindrical segments extending in the axial direction of the support roller. The first and second hollow-cylindrical segments are connected by a ring-shaped segment extending either in the radial direction of the support roller or at an angle to the radial direction.

A part-bearing-ring of a rolling-element bearing includes first and second assembly bores on its end surface, and the second assembly bore has a larger diameter than the first assembly bore so that it can accommodate a securing sleeve. The second assembly bore may include an internal thread for attaching the securing sleeve. Also a bearing ring formed of two part-bearing-rings and a securing sleeve and a method of installing a bearing ring.

Part-bearing-ring, securing sleeve, rolling-element bearing, and mounting method

A rolling-element bearing includes a first bearing ring () and a second bearing ring () opposing the first bearing () in a radial direction (). A sealing element () of the rolling-element bearing includes a radially-encircling seal support () extending in the radial direction () by a predetermined distance towards the second bearing ring (). The seal support () is interference-fit and removably attached to an axial end side () of the first bearing ring (). A sealing lip () is attached to the seal support () and extends from an end of the seal support () opposite the first bearing ring () in the radial direction () up to a mating surface (), which is part of the second bearing ring ().

A bearing arrangement () for a tension roller () designed as a hollow cylinder at least in segments, having at least one bearing () supporting the tension roller (), wherein a damping layer () made of elastomer or rubber material is disposed between a ring () of the bearing () and the tension roller (), directly or indirectly, and wherein at least one axial end of the tension roller () is closed by a cover (). In order to achieve a low-noise and self-centering seal for the axial end of the tension roller, according to the invention, the cover () is disposed in a mounting segment () and is held by the same, said segment being molded from the material of the damping layer in an axial end region of the damping layer ().

A support roller assembly comprises a support roller formed at least in part as a hollow cylinder. At least two bearings are spaced from each other in the axial direction of the support roller and rotatably support the support roller. At least one cushioning element is disposed within the support roller in the axial spacing between the two bearings. The cushioning element includes at least one ring made of cushioning material that extends adjacent the inner surface of the support roller.

Support roller assembly

A bearing assembly is configured to be axially mountable in a support roller as a single structural unit. The support roller includes an at least partially hollow-cylindrical support roller shell and a support roller shaft. The bearing assembly comprises a mounting element configured to axially slide on the support roller shaft for mounting the bearing assembly in the support roller, a roller bearing having an inner ring fixedly supported on the mounting element, a support body radially surrounding the roller bearing, a cushioning layer radially surrounding the support body, and a sleeve radially surrounding the cushioning layer. The sleeve is configured to slidably contact an inner cylindrical surface of the support roller shell.

Bearing arrangement for a load-bearing roller

A process for producing a bearing assembly includes positioning a first sleeve element in an injection mould, the injection mould having a cylindrical recess with a diameter for receiving the first sleeve element and the outside diameter of the first sleeve element being lesser than the diameter of the recess. A second sleeve element is positioned concentrically within the first sleeve element in the injection mould to define an annular chamber and elastomeric material in a molten state is injected under pressure into the annular chamber between the sleeve elements such that the outside diameter of the first sleeve element is expanded. The elastomeric material is allowed to solidify in the annular chamber between the two sleeve elements and the assembly of sleeves and elastomeric material are removed as a unit from the injection mould.

Bearing assembly with elastomeric sleeve element

A bearing assembly () includes at least one bearing () that rotatably supports a cylindrical roller tube (). A cushioning layer () is disposed, directly or indirectly, between a ring () of the bearing () and the cylindrical roller tube (). At least one contact surface () for the cushioning layer () extends over a defined axial distance (L) at an angle (&#x3b1;) to the rotational axis (A) of the bearing assembly ().
