Details
Spherical roller bearings are robust, self-restraining construction assemblies with double-rows of symmetrical spherical roller bearings. The axis of the roller rows are inclined at an angle to the turning axis of the bearing. The raceway in the outer ring is spherically formed so that the double-row roller assembly can adjust itself easily in case of misalignments or shaft deflections.
The extremely high load capacity, angle-adjustable self-adjusting roller bearings are used where high impact radial dynamic forces have to be absorbed and misalignments or larger shaft deflections are to be expected. They exist in many designs – from standard bearings to industry-specific specialised bearings.
