Abstract

A sealed spherical roller bearing assembly, having an outer ring with a seal groove and an inner ring with a central bore. A plurality of rolling elements is arranged between the inner ring and the outer ring. A seal is provided that has a sealing element on an outer diameter of the seal, which sealing element engages in the seal groove in the outer ring.

Claims (11)

1. A sealed spherical roller bearing assembly, comprising:

an outer ring having a seal groove;

an inner ring having a central bore;

a plurality of rolling elements arranged between the inner ring and the outer ring, the inner ring and the outer ring having an internal arrangement of a spherical roller bearing;

a seal having a sealing element at an outer diameter of the seal, which sealing element engages in the seal groove in the outer ring;

an L-shaped inner component and an L-shaped outer component, the inner and outer components each having a short leg attached to an outer radial surface of the inner ring and a long leg extending perpendicularly from the short leg in a direction of the outer ring, the long legs being parallel to and spaced from one another, and an intermediate component extending from the outer ring centrally between the long legs of the inner and outer components; and

sealing elements provided in a radially inner region of the intermediate component and extending from the intermediate component toward the long legs of the inner and outer components so as to maintain positioning of the intermediate component between the inner and outer components.

2. The roller bearing assembly according to claim 1 , wherein the long leg of an outer component has a radially outer end region that is angled toward the outer ring.

3. The roller bearing assembly according to claim 1 , and further comprising an adapter sleeve, the inner ring being mounted on the adapter sleeve, the adapter sleeve having an axially inwardly directed shoulder that abuts an axially outer surface of the inner ring.

4. The roller bearing assembly according to claim 3 , wherein a passage for hydraulic fluid is provided in the adapter sleeve.

5. The roller bearing assembly according to claim 1 , wherein a seal is provided at both axial ends of the outer ring.
