Open toroidal roller bearings combine self-aligning capability with the ability to accommodate axial displacement within the bearing. They are used as non-locating bearings in systems affected by shaft deflection, thermal expansion and heavy radial loading.
Available models and complete dimensional data are listed in the following parameter table tabs.
