Family specifications and selection conditions
| Product description | Spherical roller thrust bearings accommodate very heavy axial and considerable radial loads. They have the highest load rating of all thrust bearings, enabling compact, high power density bearing arrangements. By combining two or more spherical roller thrust bearings, it is possible to create a bearing arrangement that is either self-aligning, allowing misalignment of the shaft, or very stiff. |
|---|---|
| Manufacturer features | High load carrying capacity • Can accommodate combined loads • Allow misalignment or create very stiff bearing arrangements • Long service life and low friction • Separable design |
